Exotic invertebrates & others case method: 50 questions

7 a.m. A terrestrial tarantula (female, about 4 years old) you have kept for two years is lying on its back in the middle of the enclosure with its legs pointing up, not moving. It has ignored crickets for the past three weeks and its abdomen had turned dark. The day before, it laid down a thick mat of silk on the substrate. You have never seen this before, fear it has died, and are debating opening the lid and flipping it over with tongs.

What is the most appropriate response at this point?

1. Decide it has died and pick it up with tongs to check
2. Recognize the molting posture; close the lid, keep it dark and quiet, and do not touch
3. Spray water directly on its body with a mister to see if it reacts
4. Add two live crickets to perk it up and watch

AnswerB. Recognize the molting posture; close the lid, keep it dark and quiet, and do not touch

ExplanationFasting, a darkened abdomen, a thick silk mat and lying on its back are classic signs of a tarantula before and during a molt, not an abnormality. During a molt the exoskeleton is soft, and even slight stimulation can stall the molt or cause fluid loss, which is fatal, so the correct answer is to leave it completely alone, close the lid, and wait in the dark and quiet. Flipping it with tongs causes incomplete molts or abdominal damage. Misting the body directly puts heavy stress on a molting animal. Live crickets can chew on the defenseless molting animal and kill it. Only if the molt makes no progress for several hours or more should you consult a specialist shop or clinic. A dead tarantula lies with its legs limp and stretched out, which is distinguishable from the on-its-back posture.

IssuesDespite seeing the warning signs of fasting and a darkened abdomen, the owner did not know the molting posture and nearly mistook it for death. Without understanding the unique physiology of molting, exotic invertebrate keepers can mistake a normal state for an emergency and intervene fatally.

ImprovementLearn the signs of an approaching molt (fasting, darkened abdomen, silk mat, lying on its back) when you start keeping the animal, and note the last molt date and the start of fasting in a logbook. Agree as a family that when a molt is suspected, no prey goes in, humidity is maintained, and the animal is only observed for 24 hours.

1 a.m. You notice your arboreal tarantula molting. The cephalothorax and abdomen are free, but four legs are caught in the old skin and it has not moved for two hours. It is winter with the air-conditioner heating on, and the hygrometer in the enclosure reads 40%. The water dish has been empty for the past few days. You are thinking that grabbing the old skin with tongs and pulling it off would save it.

What is the most appropriate response?

1. Grab the old skin with tongs and pull it off in one go to free the legs
2. Soak the animal in the water dish to soften the old skin and peel it off by hand
3. Warm it with a hair dryer to speed up the molt
4. Raise the humidity in the enclosure, keep it dark, and watch for several hours without touching

AnswerD. Raise the humidity in the enclosure, keep it dark, and watch for several hours without touching

ExplanationThe main causes of an incomplete molt are low humidity and dehydration, so the first step is to mist the walls to raise humidity, keep it dark and avoid any stimulation. Legs right after a molt are extremely soft; forcing off the old skin tears legs off or causes fluid loss and death. Only if old skin remains after several hours, soften it with a damp cotton swab, and never force it off. Soaking in water risks drowning as water enters the book lungs, and hot air from a dryer worsens things through rapid drying and heat. If it cannot move at all for several hours or more, this is an emergency: contact a clinic that treats invertebrates or a specialist shop right away.

IssuesWinter heating dropped humidity to 40% and the water dish was left empty going into the molt. The owner noticed the pre-molt fasting but neglected humidity and water, raising the risk of an incomplete molt themselves.

ImprovementKeep a hygrometer in the enclosure and check daily during the heating season that humidity suits the species (around 70% for arboreal species). Never let the water dish run dry. When fasting starts, mist more often, and keep contacts (specialist shop, clinic) for incomplete molts noted in advance.

An August evening. Your arid-species tarantula (male, about 3 years old) is outside its shelter, curled up small with its legs folded under its body, not moving. The abdomen is clearly shrunken. You just got home from a week-long trip and the water dish was completely dry. Room temperature is 29°C. When you blow on it, the legs move slightly.

What is the most appropriate first action?

1. Move it to a container with damp paper towel and shallow water, and bring its mouth close to the water
2. Assume it is weak and immediately give it a live cricket for nutrition
3. Hold it in your palm to warm it while you watch it recover
4. Force water into its mouth with a dropper to rehydrate it all at once

AnswerA. Move it to a container with damp paper towel and shallow water, and bring its mouth close to the water

ExplanationLegs folded under the body, the "death curl," is a sign of a dying animal from severe dehydration, and the dry water dish and 29°C environment strongly suggest dehydration. The correct answer is to move it to an ICU container with damp paper towel and a shallow water dish, and bring its mouth (below the fangs) close to the water so it can drink on its own. If treated while it still responds, it may recover within hours to the next day. A weakened animal cannot eat a live cricket and may instead be chewed on. Holding it in your hand risks a fall and a ruptured abdomen. Forcing water with a dropper pushes water into the mouth and book lungs and can drown it. If there is no recovery by the next day, consult a specialist shop or an invertebrate clinic that same day.

IssuesThe owner did not anticipate the water dish drying out completely during a week away and had no backup for water. The assumption that an arid species needs no water led to summer dehydration.

ImprovementBefore leaving, fill the water dish and ask family or a friend to top it up. Even for arid species, keep a shallow water dish at all times and change it every 2–3 days in summer. Learn what a death curl looks like and how to set up an ICU container, and keep the materials on hand.

A night during the rainy season. You notice many tiny white specks moving around the mouth of your humid-species tarantula. The area around the mouth looks white and sticky, and it has not responded to food for about two weeks. The abdomen is not darkened. The substrate is very wet and smells moldy, and the carcass of a cricket left uneaten three days ago is still on the floor.

What is the most appropriate response?

1. Lightly spray a mite insecticide inside the enclosure
2. Move the animal to a separate container, replace all substrate, remove the carcass, and seek advice the same day
3. Assume pre-molt fasting and watch for another two weeks
4. Wipe the mouth with an alcohol swab to remove the mites

AnswerB. Move the animal to a separate container, replace all substrate, remove the carcass, and seek advice the same day

ExplanationWhite specks clustered around the mouth with refusal to eat is a classic mite infestation; left alone, the mouth gets blocked and the animal weakens. This needs same-day action: first move the animal to a clean separate container, replace all the overly wet substrate, and remove uneaten prey. At the same time, consult a specialist shop or an invertebrate clinic. Insecticide spray is the most dangerous chemical for these animals and causes convulsions and death. With no darkening of the abdomen, a pre-molt is unlikely, and waiting lets it weaken further. Alcohol is absorbed through the exoskeleton and is toxic, and wiping the mouth is itself a severe stressor. Mites explode in wet conditions with prey remains, so fixing the environment is the fundamental solution.

IssuesUneaten prey was left for three days and the substrate stayed wet and moldy. Over-wetting because it is a humid species, with poor ventilation and cleaning, let the mites multiply. Assuming the fasting was pre-molt delayed observation.

ImprovementMake it a habit to always remove uneaten prey the next day. Check substrate monthly and replace it all if mold or mites appear. Even for humid species, do not wet the substrate until it is soggy, and ensure ventilation. When the animal stops eating, always check the abdomen color and the mouth.

A November night. Your desert scorpion (adult), kept for one year, has been sluggish for several days, and the gaps between its abdominal segments look contracted and shrunken. It has not responded to food for 10 days. Because it is an arid species, you provided no water dish and never misted. A heat mat warms the entire floor of the enclosure, and the inside reads 33°C.

What is the most appropriate first action?

1. Add a shallow water dish and move the heater to the side to bring the temperature down to 22–28°C
2. It is a desert animal, so give no water and raise the heater temperature further
3. Assume malnutrition and feed it a pinky mouse
4. Press the abdomen with a finger to check for dehydration

AnswerA. Add a shallow water dish and move the heater to the side to bring the temperature down to 22–28°C

ExplanationA shrunken abdomen signals dehydration or malnutrition, and an environment with no water dish and the whole floor heated to 33°C drives dehydration fast. The correct answer is to add a shallow water dish, move the heat mat to the side of the enclosure to create a retreat, and return the temperature to the proper 22–28°C. Even arid species need a water dish, and above 30°C is the danger zone. Turning up the heater worsens dehydration. Vertebrate prey like pinky mice is too rich for these animals, burdens a weakened one, and live prey may bite. Pressing the abdomen with a finger invites stings and body damage. If there is no improvement by the next day, consult a specialist shop or clinic the same day.

IssuesThe misconception that desert animals need no water combined with full-floor heating that left no escape from the heat. There was a thermometer in the enclosure, but the owner did not know the danger thresholds.

ImprovementEven for arid species, keep a shallow water dish at all times and change it every 2–3 days. Attach the heater to the side of the enclosure to create a temperature gradient. Keep a thermometer and hygrometer inside and check daily, treating above 30°C and below 15°C as danger lines.

Saturday morning. Your juvenile tarantula, kept for six months, finished molting last night and looks beautiful and a size larger. It has not eaten for a month, so you figure it must be hungry; watching it move about at the front of the enclosure, you want to drop in a fairly large cricket right away. The molted skin is still in the enclosure.

What is the most appropriate response?

1. It must be hungry, so immediately add a large cricket more than half its body size
2. Add three live crickets at once for nutrition
3. Pick it up to inspect each leg after the molt
4. Remove the molted skin the next day, wait about a week before feeding, then give a smaller prey item

AnswerD. Remove the molted skin the next day, wait about a week before feeding, then give a smaller prey item

ExplanationRight after a molt, the exoskeleton and fangs are soft and take several days to a week to harden. Adding live crickets during this time can lead to the animal being chewed on and dying from fluid loss. Until the fangs harden it cannot catch prey, and forcing a meal damages the mouthparts. The correct answer is to hold off feeding for about a week after the molt, then offer one smaller prey item less than half its body size. Remove the molted skin the next day; it can be used for sexing and records. A prey item larger than half the body, or several at once, multiplies the risk of attack on the soft animal. Picking it up risks a fall and abdominal rupture, as well as damage to the still-soft legs.

IssuesThe mammal-style thinking that "it hasn't eaten for a long time, so it's hungry" ignored the post-molt hardening period unique to these animals. The owner did not recognize that feeder insects can turn into predators.

ImprovementRecord the molt date and set feeding to resume one week later. Offer 1–2 prey items under half the body size, and remove them within a few hours if uneaten. After a molt, just set up the water dish and observe through the enclosure.

A January morning. Your giant centipede, kept for two years, has been curled up at the bottom of the substrate barely moving for two days and ignores a cricket offered with tongs. The enclosure sits on a shelf near the front door, and the thermometer inside reads 13°C. There is no shrunken abdomen or fluid leak, and the body surface looks normal. No heating device was installed.

What is the most appropriate first action?

1. Assume illness and place the whole enclosure in front of a space heater to warm it fast
2. Attach a heat mat to the side, move it to a warm room, and gradually bring it back to 22–28°C
3. Worried about fasting, force the cricket against its mouth with tongs
4. Assume it has gone into hibernation and leave it untouched until spring

AnswerB. Attach a heat mat to the side, move it to a warm room, and gradually bring it back to 22–28°C

ExplanationBelow 15°C is the danger zone for these animals; at 13°C the metabolism drops so it cannot move or eat. With no abnormality on the body or abdomen, low temperature is the likely cause, so attach a heat mat to the side of the enclosure, move it to a warm room, and gradually return it to the proper 22–28°C. Rapid warming in front of a space heater can push it past 30°C or dry it out, which is fatal. Full-floor heating also leaves no escape, so avoid it. Forcing food on an animal immobilized by cold does not work and invites a bite. These animals do not hibernate like mammals; leaving them in the cold leads to death from weakness. If it still does not eat or move several days after returning to the proper temperature, consult a specialist shop or clinic.

IssuesThe enclosure was kept without heating in a cold spot near the front door in winter, and the owner looked at the thermometer without registering the danger threshold. False assumptions like "not moving means sick" and "bugs hibernate" clouded judgment.

ImprovementIn winter, attach a heat mat to the side of the enclosure and keep it in a warm room where people spend time. Check the thermometer every morning and treat below 15°C and above 30°C as warning lines. Prepare backup warming for power outages and absences in advance.

Sunday noon. Your terrestrial tarantula (female, about 8 years old) flipped onto its back and began molting around 6 a.m. Six hours have passed, but the carapace has only lifted slightly and nothing has progressed; the legs barely move. Humidity is 70% and the enclosure is at 25°C. Previous molts finished in 2–3 hours. There is no clinic nearby that sees invertebrates, but the specialist shop where you bought it is open.

What is the most appropriate response?

1. It is just taking longer than before, so wait another day before deciding
2. Raise the humidity further and phone the specialist shop or an invertebrate clinic right now
3. Gently lift and peel off the carapace with your fingers to help the molt
4. Lightly shake the enclosure to see if stimulation gets it moving

AnswerB. Raise the humidity further and phone the specialist shop or an invertebrate clinic right now

ExplanationBeing unable to move mid-molt for several hours or more is an emergency contact situation. Large, older females in particular take longer to molt and can run out of strength partway. The correct answer is to raise the humidity further while keeping it dark, phone the specialist shop or an invertebrate clinic right now, give the species, last molt date, temperature and humidity, and follow their instructions. Waiting another day loses the chance of recovery in a stalled molt. Peeling the carapace with your fingers tears the soft body and causes fluid loss. Shaking the enclosure can interrupt the molt or cause fall injuries. Even if the owner intervenes, keep it to softening with a damp cotton swab under instruction, and never force anything off.

IssuesKeeping records of normal molt times was good, but the owner did not know an abnormally long molt counts as an emergency and kept waiting. They had not checked, when starting out, that no nearby clinic sees invertebrates.

ImprovementBefore keeping the animal, look up contact details and hours for invertebrate clinics and specialist shops. Record every molt (start time, duration, humidity) and set a rule to seek advice once it takes more than twice the usual time. Manage humidity especially carefully for older animals during molting.

Friday night, the usual feeding day. Your juvenile tarantula, kept for a year, has been holed up deep in its burrow for about 10 days, and through the enclosure you can see its abdomen has darkened. The cricket added last week was not eaten; it ran around and is still walking on the substrate. Your husband says "it'll get weak if it doesn't eat" and is about to add more prey.

What is the most appropriate response?

1. Remove the remaining cricket right now, add no new prey, and wait for the molt
2. Add two more crickets for this week so it does not get weak
3. Push a cricket into the burrow entrance to stimulate its appetite
4. Pull the animal out of the burrow with tongs to check its condition

AnswerA. Remove the remaining cricket right now, add no new prey, and wait for the molt

ExplanationA darkened abdomen, hiding in the burrow and refusing food are normal pre-molt signs, and leaving a live cricket in the enclosure at this time lets it chew on the defenseless molting animal and inflict fatal wounds. The correct answer is to remove the remaining cricket, add no new prey, maintain humidity, and wait for the molt. Adding prey only increases the danger, and pre-molt fasting of several weeks to over a month is normal. Pushing prey into the burrow entrance severely stresses a pre-molt animal, and pulling it out with tongs leads to lost legs, falls and incomplete molts. Feeding can resume about a week after the molt.

IssuesA family member's belief that "it'll weaken if it doesn't eat" led to mistaking pre-molt fasting for illness. The uneaten cricket was left for a whole week, showing no awareness that feeder insects can become predators.

ImprovementShare the pre-molt signs (fasting, darkened abdomen, hiding in the burrow) with the whole family. Always remove uneaten prey within a few hours and keep a feeding log. Once a pre-molt is suspected, stop feeding and only maintain the water dish and humidity.

A June weekend. Opening the enclosure of your large Tanzanian millipede, you find white mold spread over the substrate surface and many tiny white bugs moving about. The millipede has stayed buried in the substrate and has barely been seen for days. You have been misting generously every day and taped over some of the ventilation holes to prevent mold.

What is the most appropriate response?

1. Spray rubbing alcohol inside the enclosure to prevent mold
2. Move the animal to a separate container, replace all substrate, uncover the vents, and mist more sparingly
3. The millipede is out of sight so it is fine; just remove the moldy parts with your fingers
4. Mold goes away on its own, so mist even more often and watch

AnswerB. Move the animal to a separate container, replace all substrate, uncover the vents, and mist more sparingly

ExplanationMillipedes like a damp leaf-litter environment, but heavy daily misting and blocked ventilation create excess moisture and stagnant air, causing mold and mites to explode. The correct answer is to move the animal to a separate container, replace all substrate, uncover the blocked vents, and keep the substrate only moderately damp. Millipedes are non-venomous but release a foul fluid when disturbed, so move them gently with a cup or tongs. Spraying alcohol or disinfectant is absorbed through the exoskeleton and causes poisoning. Removing only part of the mold leads to recurrence if the environment is unchanged, and you may miss a weakened millipede hiding below. More misting only makes things worse.

IssuesThe misconception that "a humid species does better the wetter it is" and the counterproductive step of blocking ventilation to prevent mold. The monthly substrate check was skipped, and the animal staying hidden was taken as reassurance.

ImprovementAim for substrate damp enough that no water seeps out when squeezed, and confirm 70–80% on the hygrometer. Never block ventilation holes. Dig through the substrate monthly to check its condition and replace it all if mold or mites appear. Remove leftover food and droppings promptly.

Tuesday morning. Your juvenile arboreal tarantula finished molting last night, but two hind legs are bent at the base and will not straighten, and it walks awkwardly. The old skin came off cleanly. There is no fluid leak, and it was seen approaching the water dish and drinking. You are thinking that straightening the bent legs would fix them.

What is the most appropriate response?

1. Carefully straighten the bent legs with tongs to correct them
2. Bent legs will likely improve at the next molt, so do not touch and place water and food nearby
3. Cut a small piece of a human medicated patch and stick it on the leg to treat the joint
4. Decide it cannot survive if it cannot walk and give up on keeping it

AnswerB. Bent legs will likely improve at the next molt, so do not touch and place water and food nearby

ExplanationThis is a form of incomplete molt where legs harden in a bent position. With no fluid leak and the animal drinking, the risk to life is low, and in a juvenile the legs are likely to regenerate and improve at the next molt. The correct answer is not to touch it and to place the water dish and food nearby so it can rest. Straightening hardened legs with tongs breaks the joints, causes fluid loss, and leads to autotomy or death. Human patches or medications are absorbed through the exoskeleton and can be fatally toxic. If it can walk but struggles to catch prey, place slow-moving prey nearby with tongs to get by. Keeping humidity right for the next molt is the best treatment.

IssuesHumidity during the molt was probably inadequate, so the legs did not extend normally while hardening. The owner thought "correct it and it heals" as with a mammal fracture, without understanding exoskeleton structure and regeneration at the next molt.

ImprovementJuveniles molt often, so when fasting begins, keep humidity on the high side for the species and never let the water dish run dry. Do not touch for a week after a molt, and place slow-moving prey nearby. Photograph leg abnormalities and compare after the next molt.

Sunday afternoon. You notice the center of the abdomen of your New World tarantula (adult female) is bald and shiny black. Lately you have lifted the enclosure to show visitors each time they come, and each time the animal rubbed its abdomen with its hind legs. Worried it is a skin disease, you are debating applying an over-the-counter animal skin medication.

What is the most appropriate response?

1. Assume a skin disease and apply dog/cat skin medication to the bald patch with a cotton swab
2. Feed it daily to boost nutrition until the hair grows back
3. Recognize it as the mark of flicking urticating hairs in defense; move the enclosure less often and do not touch it
4. Wipe the bald patch clean with a damp tissue

AnswerC. Recognize it as the mark of flicking urticating hairs in defense; move the enclosure less often and do not touch it

ExplanationNew World tarantulas defend themselves by flicking urticating hairs off the abdomen with their hind legs, so disturbances such as frequently moving the enclosure or showing it to visitors cause a bald abdomen. This is not a disease, and the hairs return at the next molt. The correct answer is to move the enclosure less often, not touch it, and remove the stress. Dog/cat skin medications are absorbed through the exoskeleton and are toxic, and applying them provokes more hair-flicking that can give the owner dermatitis. Daily feeding only raises the risk of obesity and abdominal rupture and does not restore hair. Wiping the bald patch damages the exoskeleton and risks getting hairs on your hands or in your eyes.

IssuesThe owner did not understand that lifting the enclosure to show visitors was a serious threat to the animal. They did not know about the hair-flicking defense or its risk of causing dermatitis.

ImprovementFix the enclosure on a stable, low stand and do not lift or move it. Observe quietly through the enclosure at night. Wear gloves and goggles for work inside, and treat a bald abdomen as a stress indicator signaling a review of the setup.

Saturday night. You placed your terrestrial tarantula (adult female) on your palm to show a friend; it suddenly moved and fell about 40 cm to the floor. It lies motionless with legs drawn in, and there is a crack in the abdomen with clear fluid seeping out. Your friend says "press it with a tissue and put on a bandage." It is 11 p.m. and the specialist shop is closed.

What is the most appropriate first action?

1. Press the wound firmly with a tissue and secure it with an adhesive bandage
2. Apply disinfectant to the wound, return it to its enclosure, and watch
3. Scoop it up gently with a cup, rest it in a small container lined with damp paper, and let the wound dry and clot
4. Decide it is dead because it is not moving and leave it on the floor until morning

AnswerC. Scoop it up gently with a cup, rest it in a small container lined with damp paper, and let the wound dry and clot

ExplanationThis is a serious accident: a tarantula can die from a ruptured abdomen after a fall of only about 30 cm. Hemolymph clots on contact with air, so the correct answer is to scoop it up gently with a cup, rest it in a small dark container lined with damp paper towel, apply nothing to the wound, and let it dry to stop the leak. If the fluid loss does not stop, emergency action is needed: contact an invertebrate clinic urgently. Pressing hard with a tissue tears the soft abdomen further, and an adhesive bandage damages the exoskeleton when removed. Disinfectant is absorbed through the exoskeleton and is fatally toxic. Lying motionless with legs drawn in is a sign of a dying animal, not death, and leaving it loses the chance to save it.

IssuesThe owner broke the cardinal rule that handling is unnecessary and dangerous, putting the animal on a hand as a show for a guest. They had no contact for nighttime emergencies and nearly followed a friend's wrong advice.

ImprovementDecide never to hold tarantulas in your hand; move them with a cup and postcard close to the ground. Keep the enclosure on a low, stable stand. Keep ICU container materials on hand and note the after-hours contact for an invertebrate clinic. Share the first aid for fluid loss, "let it dry, apply nothing," with the family.

Thursday night. While moving your scorpion with tongs to clean its enclosure, you pinched a leg; the animal thrashed and one leg came off at the base. A small amount of fluid is coming from the stump. The scorpion itself has settled in a separate container and is moving about. You are anxious to stop the bleeding.

What is the most appropriate response?

1. Apply styptic powder or super glue to the wound to stop the fluid
2. Tape the detached leg back in its original position
3. Dissolve a human painkiller in water and have it drink it to ease the pain
4. Treat it as autotomy: do not touch, place the water dish and food nearby, and wait for regeneration at the next molt

AnswerD. Treat it as autotomy: do not touch, place the water dish and food nearby, and wait for regeneration at the next molt

ExplanationThese animals shed a grabbed leg to escape. A leg lost at the base stops bleeding naturally and regenerates at the next molt, so the correct answer is not to touch it, place the water dish and food nearby, and let it rest. Styptic powder and super glue are absorbed through the exoskeleton and are toxic, doing more harm than sealing the wound. A detached leg cannot be reattached, and tape damages the exoskeleton. Human painkillers have unknown dosage and safety for these animals and can cause convulsions or death. If the fluid does not stop, or several legs are lost and it cannot move, consult a specialist shop or clinic the same day. From now on, move it by covering with a cup rather than grabbing legs with tongs.

IssuesUsing tongs to move the animal and pinching a leg directly caused the accident. There was no set cleaning procedure of "first move the animal to a separate container with a cup," and the tools were used improperly.

ImprovementMove animals with a cup and postcard or guide them with a soft brush; never grab legs or body with tongs. Clean with long tools after moving the animal to a separate container. Record the date of the lost leg and confirm regeneration at the next molt.

Midnight. You find a cricket, added three days ago and never removed, chewing on the soft abdomen of your juvenile tarantula while it molts. There is a small wound on the abdomen with a little fluid seeping out. The molt is nearly complete, but the body is still pale and soft.

What is the most appropriate first action?

1. Remove the cricket with tongs right now, do not touch the animal, and keep it dark and quiet
2. Scoop the animal up by hand and move it to a separate container to protect it from the cricket
3. Apply disinfectant to the animal's wound so it does not worsen, then watch
4. Spray the mister hard to drive the cricket away

AnswerA. Remove the cricket with tongs right now, do not touch the animal, and keep it dark and quiet

ExplanationA soft, freshly molted animal is easy prey for feeder insects, and being chewed on causes fatal fluid loss. The top priority is immediate removal of the cricket: pick out only the cricket with tongs, do not touch the animal, and keep it dark and quiet while it hardens. A small wound clots as it dries. Scooping the animal by hand damages the soft body and legs and risks a fall. Disinfectant is absorbed through the exoskeleton and is toxic, especially dangerous right after a molt. A strong spray stresses the animal and lets water into the wound, preventing it from drying and clotting. If the fluid does not stop, contact an emergency clinic; once the wound closes, keep the substrate clean to prevent secondary infection.

IssuesAn uneaten cricket was left for three days, breaking the basic rule of stopping feeding before a molt. The danger of feeder insects turning into predators was underestimated.

ImprovementRemove crickets within a few hours if uneaten. Stop feeding once fasting or a darkened abdomen appears. Write the "time added" and "time removed" in the feeding log to prevent forgetting. Add no prey for a week after a molt.

Evening. After returning the water dish to your centipede's enclosure, you slid the lid shut and caught several of the centipede's legs and part of its body in the edge. The centipede is writhing violently. A panicking family member is holding the lid down and trying to pull the animal out, saying "get it out fast."

What is the most appropriate response?

1. Grab the animal with tongs and quickly pull it out of the lid
2. Gently open the lid to release what is pinching it, and wait for the animal to free itself
3. Keep holding the lid down until it stops thrashing, then release it
4. Cut off the pinched legs with scissors to free the animal

AnswerB. Gently open the lid to release what is pinching it, and wait for the animal to free itself

ExplanationPulling a pinched animal tears off legs and splits the body, causing fluid loss. The correct answer is to gently open the pinching lid to relieve the pressure and wait for the animal to free itself. A pinched centipede thrashes violently and bites, so keep bare hands away and use long tools. Pulling with tongs leads to lost legs and body damage. Holding the lid down prolongs the compression, worsening internal damage and fluid loss. Cutting legs with scissors is needless injury; legs can be handled through autotomy or the next molt. Afterward, rest it in a dark separate container; if fluid loss continues, contact an emergency clinic, and for lost legs wait for the next molt.

IssuesThe animal's position was not checked before closing the lid. Centipedes are fast and slip into gaps easily, yet there was no set procedure for opening and closing, and the family did not know how to respond in a panic.

ImprovementAlways visually confirm the animal's position before opening or closing. Sliding lids let animals get into the edge, so consider a hinged enclosure with a lock. Share the rule "don't pull, remove the object" with the family, and keep long tongs and a cup within reach.

Saturday morning. You notice a dark clotted mass at the mouth of your terrestrial tarantula (adult) and that one fang is broken off at the base. It seems to have struck its mouth on a sharp corner of the driftwood in the enclosure while catching a cricket last night. The animal moves but does not respond to food. The fluid has now clotted and stopped.

What is the most appropriate response?

1. Apply disinfectant to the broken fang area to prevent infection
2. It will not eat, so push a cricket into its mouth with tongs
3. Do nothing to the wound, remove the sharp driftwood, withhold food for now, keep the water dish, and seek advice
4. An animal with a broken fang cannot survive, so give up on keeping it

AnswerC. Do nothing to the wound, remove the sharp driftwood, withhold food for now, keep the water dish, and seek advice

ExplanationA broken fang regenerates at the next molt, but until then the animal often cannot catch prey. Since the fluid has clotted, the correct answer is to apply nothing to the wound, remove the sharp driftwood that caused it, withhold food for the time being, just maintain the water dish, and consult a specialist shop or an invertebrate clinic. Disinfectant is absorbed through the exoskeleton and is toxic, and reopens the wound. Pushing prey into the mouth causes renewed bleeding and secondary damage, with a risk of a bite. Fang regeneration happens at the molt, and the animal can usually survive until then as long as it has water. Adults tolerate months of fasting, so there is no need to give up.

IssuesDriftwood with sharp corners was placed in the enclosure without checking layout safety. The owner did not anticipate the animal hitting decor during the violent movement of catching prey.

ImprovementPlace no sharp decor; switch to rounded cork bark or shelters. Regularly check the enclosure for hazards within the animal's range of movement. For mouth injuries, follow the rule "don't apply, don't push in" and contact your advisor with a photo.

Night. To show a visiting child, you copied a method seen in a video and lifted your scorpion by pinching the tip of its tail with tongs. The scorpion thrashed and fell, and part of a tail segment cracked with fluid seeping out. The scorpion is on the floor with its stinger raised in threat, and the child is about to approach.

What is the most appropriate first action?

1. Move the child away, cover the animal with a cup and postcard to recover it, and rest it in a container lined with damp paper
2. While it is posturing, quickly pinch its back with bare fingers and return it to the enclosure
3. Wrap an adhesive bandage around the cracked tail to stop the fluid
4. Leave it on the floor until it calms down and let the child observe

AnswerA. Move the child away, cover the animal with a cup and postcard to recover it, and rest it in a container lined with damp paper

ExplanationAn agitated scorpion is highly likely to sting, so first move the child away to prevent a sting. Recover it not with bare hands but by covering it with a cup and sliding a postcard underneath, then rest it in a dark container lined with damp paper towel and let the cracked area dry and clot naturally. Pinching the back with bare fingers is the most common cause of stings. An adhesive bandage damages the exoskeleton when removed and, by sealing the wound, prevents it from drying. Leaving it on the floor leads to escape, being stepped on, or the child being stung. If fluid loss does not stop, contact an emergency clinic; even if it stops, withhold food for a few days and observe.

IssuesThe owner copied a handling method from a video, ignoring the rule that handling is unnecessary and dangerous. They handled a venomous animal with a child nearby, without anticipating how to recover it in an accident or the risk of a sting.

ImprovementNever pinch and lift a scorpion by the tail or body. Move it with a cup and postcard, kept beside the enclosure at all times. Do not open the enclosure when children are present. Lock the enclosure and show visitors only through the enclosure.

Sunday morning. You find a small wound about 3 mm across on the abdomen of your humid-species tarantula (adult), with a little clear fluid seeping out. It apparently scraped against a corner while trying to squeeze under its shelter the day before. The animal moves normally and is drinking water. Worried about infection, you are about to apply the household wound disinfectant with a cotton swab.

What is the most appropriate response?

1. Apply disinfectant to the wound with a cotton swab to prevent infection
2. Rinse the wound with water to clean it
3. Apply a thin layer of antibiotic ointment to protect the wound
4. Apply nothing, do not touch, let it rest, and let the wound dry and clot

AnswerD. Apply nothing, do not touch, let it rest, and let the wound dry and clot

ExplanationThe hemolymph of these animals clots on contact with air, and small wounds stop bleeding naturally when allowed to dry. Disinfectants, ointments, alcohol and other chemicals are absorbed through the exoskeleton and are toxic; far from helping healing, they can cause death, so the correct answer is to apply nothing, not touch, and let it rest. Rinsing with water washes away the clotting fluid and restarts the bleeding, and spraying water directly is stressful even for humid species. Antibiotic ointment is made for humans and mammals, with no guaranteed safety for these animals. If the fluid does not stop, the wound widens, or the animal stops moving, contact an emergency clinic. Once the wound has clotted, keep the substrate clean to prevent secondary infection.

IssuesThe owner applied mammal wound care directly to an exotic invertebrate, not knowing the basic rule that disinfectants are toxic to them. The shelter corner was sharp and the enclosure safety check was inadequate.

ImprovementLearn the rule for invertebrate wounds: "let it dry, apply nothing." Choose shelters and decor with rounded edges, and give burrowing animals enough substrate depth so they do not force their way under things. Record the amount and duration of any fluid loss and note whom to contact if it does not stop.

Late at night, as your giant centipede climbed the rim of its enclosure, you instinctively grabbed the middle of its body with metal tongs to prevent escape and put it back. Afterward, fluid is seeping from between the segments where you gripped it. The centipede is moving about violently and slamming its body against the enclosure walls. You wore gloves but are shaken.

What is the most appropriate response?

1. Cover the enclosure with a cloth to darken it, let the animal calm down and the wound dry and clot, and withhold food for a while
2. Grab the animal again with tongs to examine the wound
3. Mist the substrate heavily to make it very wet to heal the wound
4. It is moving about so it must be fine; feed it a cricket as scheduled

AnswerA. Cover the enclosure with a cloth to darken it, let the animal calm down and the wound dry and clot, and withhold food for a while

ExplanationGripping a centipede's body with metal tongs tears the membrane between segments and causes fluid loss. The basic treatment is "do not touch, let it dry and clot": the correct answer is to cover the enclosure with a cloth to darken it, calm the agitated animal to stop it slamming into the walls, and withhold food until the wound has clotted. Grabbing it again widens the wound, and an agitated centipede bites hard, causing a second accident. Excess moisture prevents the fluid from drying and clotting and encourages mites and bacteria entering the wound. Running about is agitation, not a sign of health, and a cricket added before the wound clots will chew on it. If the fluid does not stop, emergency contact is needed.

IssuesThere was no plan for tool use when the centipede tried to climb out. Gripping the body with metal tongs caused the injury; escape prevention should rely on a locking lid, not physical intervention on the animal.

ImprovementRecover centipedes with soft silicone-tipped tongs or a cup and postcard, never gripping the body hard. Keep the lid locked at all times and never look away while it is open. If the animal climbs up while the lid is open, close the lid for a moment or guide it down with a brush.

Saturday morning. Looking into the enclosure of your tarantula (adult male), you see three legs are missing, its body tilts, and it can barely walk. Last night you added two large crickets for feeding and went to bed. One cricket was eaten; the other is still moving in the enclosure. The stumps are dry.

What is the most appropriate response?

1. Remove the remaining cricket, place the water dish near its mouth, let it rest, and consult a specialist shop or clinic the same day
2. It needs nutrition to regrow legs, so add more crickets
3. Decide it cannot survive if it cannot walk and just watch without doing anything
4. Leave the remaining cricket in place and wait for it to heal naturally

AnswerA. Remove the remaining cricket, place the water dish near its mouth, let it rest, and consult a specialist shop or clinic the same day

ExplanationSeveral missing legs with inability to move calls for same-day advice. First remove the remaining cricket, the source of the attack, place the water dish near the mouth so the immobile animal can drink, keep it dark and resting, and consult a specialist shop or an invertebrate clinic. Lost legs regenerate at the next molt, and even adults recover through molting, so there is hope. Adding crickets raises the risk of further chewing on a defenseless animal with missing legs. Doing nothing lets it weaken from dehydration. Leaving the cricket means another attack overnight and fatal injury. From now on, feed one prey item at a time and remove it within a few hours if uneaten.

IssuesTwo large crickets were added at once before bed, underestimating the danger of feeder insects attacking the animal. Adult males have short lifespans and declining strength, and the owner lacked awareness of matching feeding amount and prey size to the individual.

ImprovementOffer one prey item at a time, less than half the body size, and watch it eat before leaving. Remove it within a few hours if uneaten. Know that adult males need feeding only about once every 10 days. Record lost legs with photos and dates, and confirm regeneration at the next molt.

A July morning. A mass of tiny ants has invaded the enclosure of your juvenile tarantula, placed near the balcony, and they are swarming over its legs and abdomen. The animal has drawn in its legs and small wounds are visible all over its body. A trail of ants continues around the enclosure, and a family member is getting ready, saying "let's spray insecticide."

What is the most appropriate first action?

1. Spray insecticide inside and around the enclosure to wipe out the ants
2. Move the animal with a cup to a clean separate container, brush off the ants with a soft brush, and replace the enclosure and all substrate
3. Wait for the ants to leave on their own and leave the animal as it is
4. Submerge the whole enclosure in water to drown the ants

AnswerB. Move the animal with a cup to a clean separate container, brush off the ants with a soft brush, and replace the enclosure and all substrate

ExplanationAnts attack these animals in groups and can kill a juvenile within a short time. The top priority is rescuing the animal: move it with a cup to a clean separate container, brush off the clinging ants with a soft brush, and replace the enclosure and all substrate. Insecticide is the most lethal chemical for these animals; just contact with residue in the enclosure or in the air causes convulsions and death. Waiting for the ants to leave means the animal dies. Submerging the enclosure drowns the animal. After rescue, rest it in a dark container lined with damp paper, let the wounds dry and apply nothing. If fluid loss continues, contact an emergency clinic. For ant control, use water-filled trays or ant barrier tape on the enclosure legs, and never use chemicals in the same room.

IssuesThe enclosure was placed by a window near the balcony without considering ant entry routes. A spot close to outdoors in summer also heats up easily, so the placement was inappropriate. The family also did not know that insecticides are fatal to these animals.

ImprovementPlace the enclosure on a stable stand indoors, away from windows and exterior walls, with water-filled trays or other ant barriers under its legs. Keep nearby leftover food and feeder insect containers clean. Agree as a family never to use insecticides or mosquito coils in the room where the animals are kept.

Monday, 7 a.m. The lid of your terrestrial tarantula's (adult) enclosure is slightly ajar and the animal is not inside. You apparently forgot to lock it after feeding last night. The room is a small bedroom (about 10 square meters); the door was closed but the closet is open. A school-age child and a cat live in the house, and you have to leave for work in 30 minutes.

What is the most appropriate first action?

1. It is time for work, so leave with the door open and search at leisure after getting home
2. Vacuum the whole room to collect the animal
3. Spray insecticide on the floor and catch it when it comes out
4. Shut the bedroom door, keep the cat and child out, and search dark corners, shoes, bedding and the closet

AnswerD. Shut the bedroom door, keep the cat and child out, and search dark corners, shoes, bedding and the closet

ExplanationAn escaped exotic invertebrate puts family and other pets at risk from venom and urticating hairs, so the top priority is containing its range. Shut the bedroom door, keep the cat and child out, and search dark, narrow places with a flashlight: dark corners, shoes, inside bedding, the closet. Tarantulas are nocturnal and hide by day, so if you cannot find it, go to work with the room sealed and search again at night. When found, do not touch bare-handed; recover it with a cup and postcard. Leaving with the door open expands its range to the whole house, and the cat may attack it, leading to hair or bite injuries. A vacuum will certainly kill the animal. Insecticide not only kills the animal but also harms the family's health.

IssuesA simple slip, forgetting the lock after feeding, caused this; escape prevention depended on the owner's memory. In a home with a cat and a school-age child, no family safety procedure for an escape had been set.

ImprovementUse a locking lid and make a habit of saying "lock checked" aloud after closing. Keep the enclosure in a lockable room or cabinet, placed where the cat cannot reach. Share the escape procedure, "close the room, keep family and pets out, search dark places, recover with a cup," with the family and keep a cup and postcard beside the enclosure.

11 p.m. You find your pet scorpion walking in a corner of the living room floor. The enclosure lid was closed, but part of the ventilation mesh was torn. Your wife is about to press it down with a slipper, and you think it would be quickest to pinch its back with a bare hand through a tissue and put it back. No children are around.

What is the most appropriate response?

1. Pinch its back with a bare hand through a tissue and return it to the enclosure
2. Press it down with a slipper, then pinch it up once it cannot move
3. Cover it with a clear cup, slide a postcard underneath, lift it, and return it to the enclosure
4. Hold out your palm so as not to startle it and wait for it to climb on by itself

AnswerC. Cover it with a clear cup, slide a postcard underneath, lift it, and return it to the enclosure

ExplanationWhen you find an escaped animal, do not touch it bare-handed; cover it with a clear cup, slide a postcard or card stock underneath, and lift it. A clear cup lets you see the animal's position and where the stinger points while carrying it safely. A bare hand through a tissue gets stung, because the stinger easily pierces thin paper. Pressing with a slipper cracks the exoskeleton and causes fatal fluid loss. Holding out your palm is likely to get you stung by an agitated animal and risks a fall. After recovery, patch the torn mesh and check the lid. If stung, rinse under running water and cool it; seek medical care if swelling or numbness develops.

IssuesThe torn ventilation mesh went unnoticed, leaving an escape route open. The recovery method had not been shared with the family, so options that kill the animal (pressing with a slipper) or are dangerous (bare-hand pinching) came up.

ImprovementInspect ventilation holes and lid gaps monthly. Use only fine ventilation holes the animal cannot pass through, and repair any tear immediately. Keep a clear cup and postcard beside the enclosure, and show the family the recovery procedure and practice it.

Sunday noon. While lowering your tarantula's (adult) enclosure with both hands from a 1.5 m high shelf for cleaning, it slipped and tilted, and the animal inside was slammed against the wall. The enclosure did not hit the floor, but the animal has drawn in its legs and is hiding in the shadow of its shelter. From the outside there is no visible fluid leak.

What is the most appropriate response?

1. Set the enclosure on a low, stable stand as is, darken it, do not touch for several hours, and watch for fluid leaks
2. Take the animal out and feel its whole body to check it is unharmed
3. Add its favorite cricket right away as an apology for the fright
4. Mist the animal generously with water to calm it, just in case

AnswerA. Set the enclosure on a low, stable stand as is, darken it, do not touch for several hours, and watch for fluid leaks

ExplanationAn impact inside the enclosure carries the same risk of abdominal rupture as a fall, but with no visible fluid leak and the animal hiding on its own, the correct answer is to first set the enclosure on a low, stable stand, darken it, not touch it for several hours, and watch through the enclosure for fluid from the abdomen or leg abnormalities. Taking it out and touching it widens any damage and risks another fall or hair-flicking. Adding a cricket risks it chewing on an animal possibly injured by the impact. Misting directly is stressful and, if there is a small wound, prevents it from drying and clotting. If fluid loss or a leg-curling posture appears after several hours, contact an emergency clinic.

IssuesThe enclosure was kept on a high 1.5 m shelf and lifted down every time it was cleaned. The owner did not recognize that moving the enclosure itself risks impact to the animal and fall accidents.

ImprovementFix the enclosure on a stable stand below waist height and set it up on the assumption it will not be moved. Clean in place after moving the animal to a separate container with a cup. If it must be carried, support the bottom with both hands, confirm the animal is inside its shelter, and carry it only a short distance.

Saturday afternoon. While you had the enclosure of your juvenile arboreal tarantula open to replace part of the substrate, the animal suddenly ran up the wall and out through the open lid onto the desk. The desk is 70 cm high and the animal is running toward the edge. You only have tongs in hand; the cup is on a shelf.

What is the most appropriate first action?

1. Pinch a leg with the tongs and quickly return it to the enclosure
2. Clamp down on it from above with a bare hand to catch it
3. Block the desk edge with a hand or notebook to prevent a fall, then get the cup and cover it from above
4. Leave the room so as not to startle it and wait for it to return to the enclosure by itself

AnswerC. Block the desk edge with a hand or notebook to prevent a fall, then get the cup and cover it from above

ExplanationArboreal tarantulas are fast, and a fall from a 70 cm desk can kill it through abdominal rupture. The correct answer is to first make a barrier at the desk edge with a notebook or a gloved hand to prevent a fall, then get the cup, cover it from above, slide a postcard underneath and recover it. Pinching a leg with tongs causes autotomy or leg damage, and the agitated animal thrashes further and falls. Clamping down bare-handed leads to bites, hair dermatitis and crush injury to the animal. Left alone, it falls off the desk or escapes into the room, endangering the family and the animal. In future, move the animal to a separate container with a cup before cleaning.

IssuesSubstrate was replaced with the animal still in the enclosure, without anticipating the speed of an arboreal species. The recovery cup was out of reach, and work began with inadequate tool preparation.

ImprovementBefore cleaning, move the animal with a cup to a separate container with a lid. Always keep a cup and postcard beside the enclosure. Work on the floor at a low position, not on a desk, leaving no room for a fall. Keep the room door closed while working.

2 a.m. A loud noise wakes you; the scorpion's enclosure has fallen from the living room shelf, the lid is off and the substrate is scattered. The cat is prowling around the enclosure, pawing at the substrate. The scorpion is nowhere to be seen. Only you and the cat are home, and the cat's face and legs show no abnormality.

What is the most appropriate first action?

1. Put the cat's safety first: pick it up, take it to another room, then come back
2. Sift through the scattered substrate with bare hands to find the scorpion
3. Vacuum up the substrate and wait for the scorpion to come out
4. Isolate the cat in another room and shut the door, then search outward from the enclosure with gloves and a flashlight and recover it with a cup

AnswerD. Isolate the cat in another room and shut the door, then search outward from the enclosure with gloves and a flashlight and recover it with a cup

ExplanationWith a venomous scorpion and a cat in the same space, either the cat gets stung or the cat kills the scorpion. The correct answer is to isolate the cat in another room and shut the door, get gloves and a flashlight, search the substrate and furniture gaps outward from the enclosure, and recover it with a clear cup and postcard when found. Carrying the cat out is right in itself, but returning without sealing the search area lets the escape range widen, so isolate the cat and seal the room at the same time. Sifting substrate bare-handed is a classic way to get stung. A vacuum will certainly kill the animal. Rest the recovered animal in a container lined with damp paper and check for fall injuries (fluid loss, legs curled under). If the cat shows lethargy, drooling or a swollen leg, take it to a veterinary hospital.

IssuesIn a home with a cat, the enclosure was on a shelf the cat could reach, neither locked nor secured. The risk of keeping a cat and an exotic invertebrate in the same room was underestimated, and no procedure for a nighttime accident had been planned.

ImprovementKeep the enclosure in a room the cat cannot enter or in a lockable cabinet with doors, secured against tipping. Use a locking lid. For nighttime accidents, keep gloves, a flashlight, a clear cup and a postcard together in one place. Also note the contact for an emergency (after-hours) animal hospital in case the cat is stung.

Sunday morning. You discover your 3-year-old, who was playing in the living room, has opened the tarantula's lid and has a hand inside. The animal is a New World species and is rubbing its abdomen with its hind legs. The child has not been bitten yet, but the hand is right in front of the animal. The mother screams and is about to yank the child's hand out.

What is the most appropriate first action?

1. Yank the child's hand out fast and close the enclosure
2. Leave the child's hand where it is so as not to startle the animal, and wait for it to move away
3. Calmly tell the child not to move, have them slowly withdraw the hand, then rinse the child's hand and eyes under running water
4. Pin the animal down with tongs, then pull out the child's hand

AnswerC. Calmly tell the child not to move, have them slowly withdraw the hand, then rinse the child's hand and eyes under running water

ExplanationRubbing the abdomen with the hind legs is the defensive behavior just before flicking urticating hairs, and sudden movement triggers a bite or a mass release of hairs. The correct answer is to calm the child with a quiet voice, have them withdraw the hand slowly, close the lid, rinse the hand and face that may carry hairs under running water, and not let them rub their eyes. Yanking the hand out makes the animal bite reflexively, or the child's hand hits the animal or wall, causing abdominal rupture or a fall. Leaving the hand in place prolongs the time it can be bitten. Pinning the animal with tongs injures it and provokes a bite. Afterward, if there is skin redness, intense itching, eye pain or redness, see a dermatologist or eye doctor. If bitten, rinse under running water, and seek emergency care for swelling, numbness or breathing difficulty.

IssuesThe enclosure was in a living room with a toddler, unlocked and within the child's reach. The rule for these animals is "a place children and other pets cannot open, with a lock," and the danger was left unaddressed at the setup stage.

ImprovementKeep the enclosure in a room children cannot enter or in a locked cabinet, and add a padlock or door lock on top of the locking lid. Repeatedly teach children not to touch the enclosure. Share first aid for urticating hairs and bites (rinse under running water, don't rub the eyes, when to seek care) with the whole family.

Night. In your centipede's enclosure, the heavy ceramic water dish tilted and tipped over because of burrowing, and part of the animal's body is trapped underneath. The centipede is thrashing its front half violently, but the rear half will not come free. The substrate under the dish has been dug out into a hollow. You have gloves, long tongs and a cup at hand.

What is the most appropriate response?

1. Grab the front half with tongs and pull it out from under the dish
2. Press the dish down from above to flatten the substrate so the animal can free itself
3. Leave it until morning without moving anything, then decide
4. Put on gloves, lift the dish away gently, wait for the animal to free itself, and rest it in a separate container

AnswerD. Put on gloves, lift the dish away gently, wait for the animal to free itself, and rest it in a separate container

ExplanationThe rule for trapping accidents is "don't pull the animal, remove the object." The correct answer is to put on gloves, lift the dish straight up gently to relieve the pressure, not touch the agitated centipede but wait for it to free itself, then move it with a cup to a separate dark container to rest, and check for fluid loss or lost legs. Pulling with tongs splits the body and tears off legs. Pressing the dish down increases the pressure and causes internal injury. Leaving it until morning prolongs the compression, fluid loss progresses, and it dies. If fluid loss continues after release, contact an emergency clinic; for lost legs, wait for the next molt. An agitated centipede bites, so keep bare hands away.

IssuesDespite knowing centipedes burrow deeply, a heavy ceramic dish was placed on top of the substrate. The basic rule of no heavy objects in the enclosure was ignored, and the risk of a hollow forming and the dish tipping was not anticipated.

ImprovementChoose a light, shallow water dish and set it directly on the enclosure floor or stabilize it with a flat stone. Place no heavy decor or ceramics. For deep-burrowing species, use 10 cm or more of substrate and arrange things so burrowing cannot tip them. Make a weekly layout check a habit.

Evening. Your giant centipede escaped through a gap in the enclosure, ran across the bathroom floor, and slipped under the cabinet near the drain. Family members suggest "pour boiling water to flush it out" and "spray insecticide into the gap." The bathroom door can be closed. The animal is a valuable species and you want to recover it alive if possible.

What is the most appropriate response?

1. Close the bathroom door and seal the gaps, darken the room and wait quietly, then recover it with long tongs or a cup when it comes out
2. Pour boiling water to flush it out and catch it bare-handed when it bolts, taking care not to step on it
3. Spray insecticide into the cabinet gap to weaken it before recovering it
4. Assume it will escape down the drain and leave it

AnswerA. Close the bathroom door and seal the gaps, darken the room and wait quietly, then recover it with long tongs or a cup when it comes out

ExplanationCentipedes are fast and slip into small gaps, so first close the bathroom door and block the gap under it with a towel to contain its range. In the dark and quiet, the nocturnal centipede becomes active, so check with a flashlight and recover it with long (soft-tipped) tongs or a clear cup when it comes out. Boiling water kills it, and catching it bare-handed is a classic way to get bitten. Insecticide not only kills it but, even if it survives recovery, chemical exposure causes convulsions and death. Leaving it means it escapes down the drain or elsewhere in the house, and the family remains at risk of bites. Put a mesh or plug over the drain to block that escape route.

IssuesAllowing an escape through a gap shows inadequate measures against the centipede's habit of squeezing through even tiny openings. Every family suggestion would have killed the animal, and no recovery procedure had been shared.

ImprovementFor centipedes and scorpions, use a gap-free enclosure with a lock and only fine ventilation holes. Share the escape procedure, "close the door, block gaps, darken and wait, recover with tools," with the family and keep long tongs and a clear cup on hand. Keep a mesh over the drain at all times.

An August night. About an hour after lighting a mosquito coil in the bedroom, your tarantula (adult) in the same room is flailing its legs erratically, flipped over and convulsing. The windows were shut and the air-conditioner was on. The coil smoke was getting in through the enclosure's ventilation holes too. A family member says "let's film it and show the specialist shop."

What is the most appropriate first action?

1. Film the convulsions and wait until the specialist shop opens
2. Flip the animal back upright and feed it to restore its strength
3. Put out the coil, move the animal to a clean separate container, replace all substrate, and ventilate the room
4. Immerse the animal in cold water to stop the convulsions

AnswerC. Put out the coil, move the animal to a clean separate container, replace all substrate, and ventilate the room

ExplanationThe active ingredient in mosquito coils is an insecticide for insects and arthropods, and it is lethal to these animals. The top priority is stopping the exposure: put out the coil, move the animal with a cup to a clean separate container, replace all the substrate that holds the residue, and open the windows to ventilate. Then keep it dark and quiet and watch over it with damp paper and a shallow water dish. Filming and waiting prolongs the exposure and loses the chance of recovery. Flipping it over damages a convulsing animal, and it cannot eat; prey would instead chew on it. Immersion in cold water drowns it. If convulsions continue, recovery is difficult, but moving it early to a clean environment can allow recovery from mild exposure. Contact the specialist shop or clinic after moving it.

IssuesThe owner did not grasp the basic fact that these animals are arthropods and die from insecticides and mosquito coils. With the enclosure in the bedroom, they did not consider the effect of their own mosquito control and used it in a sealed room.

ImprovementAgree as a family never to use mosquito coils, insecticides, plug-in repellents or flea/tick products in the room where the animals are kept, and post a notice at the door. Switch mosquito control to screens and physical barriers. Keep clean substrate and a spare container on hand in case of exposure.

Saturday morning. Yesterday you applied a spot-on flea/tick treatment to your dog in the living room, and the dog slept as usual on the sofa next to the scorpion's enclosure in the same room. This morning the scorpion is flipped over with its legs twitching finely. The enclosure's ventilation holes are fairly large, and the dog had been rubbing its body near the enclosure. You can think of no other cause.

What is the most appropriate response?

1. The dog's medication is for dogs so it is unrelated; change the scorpion's food and watch
2. Flip the scorpion over and wash its body in lukewarm water to remove the chemical
3. Move the enclosure as is to a sunny windowsill to warm it
4. Move the scorpion to a clean separate container, replace the substrate, move the dog to another room, and ventilate

AnswerD. Move the scorpion to a clean separate container, replace the substrate, move the dog to another room, and ventilate

ExplanationFlea/tick treatments for dogs and cats are arthropod-killing chemicals; volatile components or residue on the dog's body entering the enclosure through the air or contact cause convulsions and death in these animals. The correct answer is to move the scorpion with a cup to a clean separate container, replace the substrate, move the treated dog to another room, and ventilate. Then keep it dark and quiet and watch with damp paper and a shallow water dish. Deciding it is unrelated because it is for dogs ignores how the chemical works, and changing the food is pointless. Washing in lukewarm water lets water into the book lungs and drowns it, and flipping it causes further damage. A windowsill worsens things with heat and dryness. If convulsions continue, recovery is difficult; contact a specialist shop or clinic for advice.

IssuesThe dog and the scorpion were kept in the same room, and the owner did not know that dog medications are lethal to these animals. The enclosure's large ventilation holes also let airborne chemicals in easily. The other pet's medication schedule was never linked to the invertebrate's environment.

ImprovementKeep the invertebrate enclosure in a different room from dogs and cats, and keep the dog out of that room for several days after a flea/tick treatment. Keep spot-on treated animals away from the invertebrate room until dry. Use fine ventilation holes. Track the family's pet medication records and invertebrate care records on the same calendar.

A September evening. Out of crickets, you fed your juvenile tarantula a grasshopper caught in the nearby park. Thirty minutes later the animal is flailing its legs erratically, flipped over, and has dropped the remains of the grasshopper from its mouth. At the park there was a sign saying herbicide had been sprayed the day before. You have clean substrate and a spare container at hand.

What is the most appropriate first action?

1. Remove the grasshopper remains from its mouth with tongs, move it to a clean separate container, and watch in the dark and quiet
2. Spray a lot of water at its mouth to make it vomit the poison
3. Hold the body down with your hand to stop the convulsions
4. It needs nutrition to settle down, so add a fresh cricket

AnswerA. Remove the grasshopper remains from its mouth with tongs, move it to a clean separate container, and watch in the dark and quiet

ExplanationWild-caught insects risk carrying pesticides, herbicides and parasites, and must never be fed to these animals. The correct answer is to remove the grasshopper remains, the source of exposure, with tongs, move the animal to a clean separate container with damp paper and a shallow water dish, and watch in the dark and quiet. There is no way to make these animals vomit, and spraying lots of water gets into the book lungs and drowns it, adding stress. Holding it down damages the soft, convulsing body and risks a bite. Added prey cannot be eaten, and a cricket will chew on the immobile animal. If convulsions continue, recovery is difficult, but early removal can allow recovery from mild exposure. Consult a specialist shop or an invertebrate clinic.

IssuesA wild-caught insect was used as a substitute when crickets ran out, without recognizing the risk of pesticides and parasites. Despite seeing the herbicide sign, the owner did not consider that the insect might be contaminated.

ImprovementUse only purchased or home-bred feeder insects and always keep a week's supply in reserve. Adults tolerate weeks of fasting, so do not force feeding when prey runs out. Set a rule never to feed wild-caught insects and inform the family.

Night. You caught a cockroach in the kitchen and, thinking it the perfect size, fed it to your scorpion. The next morning the scorpion is trembling with its legs stretched out and moving unsteadily. You set out cockroach bait stations in the kitchen a few days ago, so the roach may have eaten the bait. The animal is still responsive.

What is the most appropriate response?

1. It has eaten a roach, so it is just digesting; watch for a few days
2. Force water into its mouth with a dropper to dilute the poison
3. Remove the roach remains, move it to a clean separate container, keep it dark and quiet while watching, and consult a specialist shop or clinic
4. Dissolve human activated charcoal in water and give it as an antidote

AnswerC. Remove the roach remains, move it to a clean separate container, keep it dark and quiet while watching, and consult a specialist shop or clinic

ExplanationHousehold cockroaches are very likely exposed to insecticides or bait, and an animal that eats one suffers secondary poisoning. The correct answer is to remove the roach remains, move it to a clean separate container, keep it dark and quiet, watch it with damp paper and a shallow water dish, and consult a specialist shop or an invertebrate clinic. There is no established antidote treatment for these animals; all an owner can do is remove the source of exposure and let it rest. Watching for days lets the poisoning progress. Forcing water with a dropper drowns it. Giving human medicines like activated charcoal is dangerous, with unknown dosage and safety. Never use kitchen pests as food again.

IssuesA bug in the house was seen as "free food" without considering possible exposure to household insecticides or bait. Food safety is basic husbandry, yet the owner did not connect it with the bait stations they had set out in the kitchen.

ImprovementLimit feeder insects to purchased or home-bred ones. Never feed household pests. In homes using roach bait or insecticides, keep the invertebrate room and feeder storage away from the chemicals. Record where feeders come from and make it a habit never to feed insects of unknown origin.

Sunday afternoon. You put an artificial plant from a dollar store and a cork shelter you had just glued together into your tarantula's (adult) enclosure. A few hours later, opening the enclosure, a sharp glue smell hangs inside, and the animal is moving its legs erratically around the decor and rubbing its mouth on the substrate.

What is the most appropriate response?

1. The smell will fade with time, so leave it overnight and watch
2. Leave the animal in the enclosure, remove only the decor, and ventilate
3. Mist a lot of water inside the enclosure to dilute the smell until the animal gets used to the decor
4. Move the animal to a clean separate container, remove the decor, replace the substrate, and wash and dry the enclosure

AnswerD. Move the animal to a clean separate container, remove the decor, replace the substrate, and wash and dry the enclosure

ExplanationVolatile compounds from glue and paint build up in a nearly sealed enclosure and cause poisoning symptoms in these animals (erratic movement, rubbing the mouth). The correct answer is to move the animal with a cup to a clean separate container, remove the decor, replace the substrate, wash the enclosure and dry it completely before returning the animal. Leaving it overnight continues the exposure and progresses to convulsions. Removing only the decor with the animal still inside leaves residue in the substrate and enclosure, so exposure continues. Misting does not dilute the smell and causes stress from excess moisture and mite outbreaks. In future, use unpainted, unglued supplies; if glue is needed, let items dry completely outdoors for several days before adding them. If there is no recovery, consult a specialist shop or clinic.

IssuesA freshly glued decoration and an artificial plant of unknown material were put in the enclosure without checking for chemicals or off-gassing. The owner lacked awareness that these animals are extremely sensitive to chemicals.

ImprovementChoose unpainted, unglued items like cork bark and flower pots for the enclosure. If using artificial plants or glue, dry them outdoors for several days and add them only after the smell is completely gone. Add new items a little at a time and observe the animal's behavior for a few hours.

3 p.m. in July. Returning home, the room is at 34°C and the thermometer inside your tarantula's (adult) enclosure, placed by a south-facing window, reads 33°C. The animal has left its shelter and is pressed against the wall with its legs stretched out, not moving. You had turned the air-conditioner off when you went out. About half the water dish remains.

What is the most appropriate first action?

1. Put the enclosure in the refrigerator to cool it fast
2. Spray a lot of cold water directly on the animal to lower its body temperature
3. Move the enclosure out of direct sunlight and use the air-conditioner to gradually bring the room back to 22–28°C
4. The animal is moving so it is fine; open the window to let in outside air

AnswerC. Move the enclosure out of direct sunlight and use the air-conditioner to gradually bring the room back to 22–28°C

ExplanationAbove 30°C is the danger zone for these animals, and pressing against the wall without moving is a sign of trying to escape the heat. The correct answer is to move the enclosure out of direct sunlight, use the air-conditioner to gradually bring the room back to 22–28°C, and refresh the water dish to prevent dehydration. A refrigerator causes a sudden temperature drop that disrupts the metabolism and kills it. A lot of cold water on the animal causes abrupt temperature change and stress, and water can enter the book lungs. On a 34°C day, opening the window does not lower the room temperature and raises the risk of escape. Afterward, if a death curl or shrunken abdomen appears, move it to an ICU container, and if it does not recover, seek advice the same day.

IssuesThe enclosure was placed by a south-facing window in direct sunlight, and the air-conditioner was turned off when going out. Summer temperature control was handled only when someone was home, without anticipating the rise in temperature during absences.

ImprovementKeep the enclosure on the interior side of a room, out of direct sunlight. In summer, run the air-conditioner at 28°C or below even when out, and check the temperature during absences with a max/min thermometer. Practice applying towel-wrapped ice packs to the outside of the enclosure in case of a power outage.

Late one January night, heavy snow causes a power outage and the heat mat stops. Two hours later the room is at 12°C and the enclosure of your humid-species tarantula has dropped to 14°C. The animal is motionless deep in its shelter. There is no word on when power will be restored. In the house you have disposable hand warmers, a styrofoam box, blankets and a portable gas stove.

What is the most appropriate response?

1. Put a disposable hand warmer directly inside the enclosure to warm it
2. Place the enclosure next to the flame of the gas stove to warm it
3. Hold the animal in your palm and keep warming it with body heat
4. Put the enclosure in the styrofoam box, place towel-wrapped hand warmers against the box's sides, and hold it around 20°C

AnswerD. Put the enclosure in the styrofoam box, place towel-wrapped hand warmers against the box's sides, and hold it around 20°C

ExplanationBelow 15°C is the danger zone for these animals, and prolonged cold leads to death from weakness. The correct answer is to put the enclosure in a styrofoam box for insulation, place towel-wrapped disposable hand warmers against the sides of the box (not touching the enclosure directly), and hold it around 20°C while watching the thermometer. A hand warmer inside the enclosure creates a local hot spot and consumes oxygen, suffocating or burning the animal. Near a gas stove there is a risk of high heat and carbon monoxide. Holding it in your hand risks a fall and abdominal rupture, and warming it that way for hours is not realistic. Avoiding full heating and leaving a retreat is the same as with normal heater management. After power returns, put the heater back on the side and gradually return to the proper temperature.

IssuesNo warming backup had been prepared for a winter outage, leaving the owner scrambling with whatever was on hand in the middle of the night. They relied on a single heat mat and had little awareness of how fast the temperature falls or of the danger zone.

ImprovementKeep a styrofoam box, disposable hand warmers and a thermometer as an "outage kit" near the enclosure. Write up and post the warming procedure for outages. In winter, keep the enclosure in the room with the most stable temperature in the house, with the heater on the side to leave a retreat.

9 p.m. A major earthquake strikes and an evacuation order is issued for your area. You keep one tarantula and one scorpion; their enclosures fell over but did not break, and the animals look unharmed. You must go to the evacuation shelter, but your family objects to bringing venomous animals. You have small plastic containers with lids and paper towels at hand.

What is the most appropriate response?

1. Put each animal in its own sealed container lined with damp paper, keep them dark and warm, and at the shelter report them to the staff and keep them away from people
2. They are venomous, so leave them at home in their enclosures, moved to a safe spot, and evacuate
3. Put both animals together in one container to keep things compact
4. Release the animals outdoors so they do not trouble anyone at the shelter, then evacuate

AnswerA. Put each animal in its own sealed container lined with damp paper, keep them dark and warm, and at the shelter report them to the staff and keep them away from people

ExplanationEvacuating with your pets applies to exotic invertebrates too: put each animal in its own sealed container lined with damp paper towel, keep it dark, avoid temperature changes, and carry it without shaking. At the shelter, report the species and whether it is venomous to the staff, and keep it in a lockable spot away from people and children. Left at home, aftershocks can topple the enclosure and let it escape, and it can die of dehydration or cold while you cannot return. These animals are solitary and cannibalistic, so two in one container will kill each other. Releasing non-native invertebrates outdoors harms the ecosystem, creates legal problems, and risks people being stung. After evacuating, do not open the container and give only the minimum water needed.

IssuesNo plan had been made for evacuating the invertebrates in a disaster, and there was no family agreement. No sealed containers or transport method were prepared, and as a keeper of venomous species the owner had not considered how to manage them at a shelter.

ImprovementPrepare an "evacuation kit": a sealed container with lid for each animal, paper towels, a thermometer and hand warmers. Stick a card on each container with the species, venom status and care temperature/humidity. Share the evacuation procedure with the family and decide what to report at the shelter. Also check disaster guides for keepers.

A December night. After turning up the air-conditioner's heating, the hygrometer in the enclosure of your juvenile humid-species tarantula reads 30%. The animal sits motionless by the water dish and its abdomen looks a bit small. For the past week it has been off its food with a darkened abdomen, so you expected a molt soon. You had been misting about once a week.

What is the most appropriate response?

1. Drier is better in preparation for a molt, so keep the heating on as is
2. Mist the animal directly to wet its body
3. Mist the substrate and walls, fill the water dish, and bring humidity back to around 70% while keeping ventilation
4. Seal the enclosure completely in plastic to trap the humidity

AnswerC. Mist the substrate and walls, fill the water dish, and bring humidity back to around 70% while keeping ventilation

ExplanationFor a humid-species juvenile about to molt, 30% humidity is a dangerous state that invites an incomplete molt and dehydration. The correct answer is to mist the substrate and walls, fill the water dish, and bring humidity back to around 70% while keeping ventilation. A humidifier in the room is also effective. The idea of drying things out before a molt is wrong; molting requires high humidity. Misting the animal directly is stressful and irritates it in its sensitive pre-molt state. Sealing completely in plastic causes oxygen shortage and excess moisture, leading to mold and mites. After restoring humidity, wait several days for the molt; if the abdomen keeps shrinking or the legs curl under, move it to an ICU container.

IssuesThe owner was unaware that winter heating greatly lowers humidity and managed a humid-species juvenile with weekly misting. They noticed the pre-molt signs but did not connect them with the humidity essential for molting.

ImprovementKeep a hygrometer in the enclosure and check it daily during the heating season. For humid species, keep the substrate damp and mist every few days according to how dry it is. When fasting or a darkened abdomen appears, keep humidity on the high side. A humidifier in the room to raise overall humidity is also effective.

A June weekend. Looking at the enclosure of your humid-species scorpion, whose ventilation holes you taped over to hold humidity, the walls are covered in droplets and white mold has spread across the substrate surface. The hygrometer reads over 95%. The scorpion has climbed the wall and clings near the top, refusing to come down. The inside smells stuffy.

What is the most appropriate response?

1. Higher humidity is better, so mist more and watch
2. Remove only the mold, leave the tape on, and let the substrate dry slightly
3. Worried about mold, spray disinfectant inside the enclosure
4. Move the animal to a separate container, replace all substrate, uncover the vents, lower humidity to 70–80%, and ensure airflow

AnswerD. Move the animal to a separate container, replace all substrate, uncover the vents, lower humidity to 70–80%, and ensure airflow

ExplanationWith ventilation blocked and humidity over 95%, this is excess moisture even for a humid species, causing mold, mites and oxygen shortage. The animal clinging near the top and refusing to come down is a sign it is fleeing the floor conditions. The correct answer is to move it with a cup to a separate container, replace all substrate, uncover the vents, lower humidity to 70–80%, and create airflow. More misting makes it worse, and removing only the mold while still sealed leads to recurrence. Disinfectant spray is highly toxic to these animals and lethal in a sealed space. Humidity for humid species is managed not by sealing but by "damp substrate and moderate ventilation." Check the substrate monthly before mold spreads, and remove uneaten food and droppings.

IssuesThe misconception that "holding humidity means sealing" led to blocking the vents, which combined with the rainy season's high humidity to cause excess moisture. The owner failed to read the sign of the animal fleeing to the top of the wall and could not judge the hygrometer reading as dangerous.

ImprovementNever block ventilation holes; adjust humidity through substrate dampness and misting frequency. Treat 70–80% on the hygrometer as the upper guideline and increase ventilation if it stays above 90%. Use a dehumidifier or the air-conditioner's dry mode in the rainy season. If the animal keeps clinging near the top, review the floor conditions.

Saturday noon. Together with your school-age child, you replaced the tarantula's substrate and cleaned the feeder cricket container. Having finished, the child is about to eat a rice ball without washing hands. Gloves were worn, but the cricket container was handled bare-handed and the substrate was touched. The mother says "bugs are clean, it's fine."

What is the most appropriate response?

1. Bugs are clean, so no handwashing is needed; let the child eat
2. Wiping hands with alcohol is enough; let the child eat without washing
3. Have the child wash hands thoroughly with soap and running water before eating, and make handwashing after care work a habit
4. Gloves were worn so the hands are not dirty; just discard the gloves and let the child eat

AnswerC. Have the child wash hands thoroughly with soap and running water before eating, and make handwashing after care work a habit

ExplanationThe enclosure, substrate and feeder insect container may carry bacteria such as Salmonella, which cause gastroenteritis when they reach the mouth via hands. Children are prone to severe illness. The correct answer is to have the child wash hands thoroughly with soap and running water before eating, and from then on make handwashing after care work a habit. The idea that "bugs are clean" is wrong; the issue is the hygiene of the substrate and feeder containers. Alcohol is less effective on organic soiling, so washing under running water comes first. Even with gloves, hands get contaminated when removing them, and the feeder container handled bare-handed is also a source. Keep feeder insect containers clean too, and wash care equipment separately from dishes.

IssuesThe zoonotic risk of keeping these animals was underestimated, and the child was allowed to help under the mistaken belief that "bugs are clean." The household had no hygiene rules for handwashing after care work or for separating care equipment from food.

ImprovementMake it a family rule to always wash hands with soap and running water after care work, and post a reminder by the sink. When a child helps, an adult supervises through to handwashing. Wash enclosures and feeder containers somewhere other than the kitchen sink, and store care equipment separately from dishes.

You keep three tarantulas and two scorpions in the same room. You found mites clustered around the mouth of one tarantula, but you have been using the same tongs and water dishes across all enclosures for feeding and cleaning, working through them in turn on the same day. The other animals show no abnormality yet.

What is the most appropriate response?

1. The other animals are fine, so keep working with the same tools as before
2. Dispose of only the mite-infested animal to protect the others
3. Lightly spray a mite insecticide in every enclosure as prevention
4. Isolate the affected animal in another room, assign tools and water dishes to each animal, do the affected enclosure last, and replace all its substrate

AnswerD. Isolate the affected animal in another room, assign tools and water dishes to each animal, do the affected enclosure last, and replace all its substrate

ExplanationMites spread to other enclosures via tools, hands and water dishes. The correct answer is to isolate the affected animal in a clean separate container, assign tongs and water dishes to each animal, start work with the healthy animals and do the affected enclosure last, and replace all its substrate. Wash and dry tools after use. Even with no abnormality in the others, continued tool sharing spreads mites to every enclosure within days. There is no need to dispose of the affected animal; it can recover with environmental improvement and substrate replacement. Spraying insecticide is the most dangerous act, killing the animals, and is no mite control. Watch the affected animal's mouth, and if it keeps refusing food, consult a specialist shop or clinic the same day.

IssuesIn a multi-animal setup, tools and water dishes were shared without understanding how infections and parasites spread. Even after finding the affected animal, there was no thought of basic hygiene measures like work order or isolation.

ImprovementProvide tongs, water dishes and misters for each animal and color-code them. Work from healthy animals to affected ones, doing any abnormal animal last. Quarantine new arrivals in a separate room for several weeks. Check all enclosures' substrate and the animals' mouths monthly, and set an isolation procedure for outbreaks.

Night. When you opened the lid to change the water dish of your New World tarantula, the animal rubbed its abdomen hard with its hind legs and hairs flew up inside the enclosure. A few minutes later your right eye has intense pain and itching with nonstop tearing, and a red rash has spread on the back of your hand. You wore neither goggles nor gloves. A family member says "rub your eye to get it out."

What is the most appropriate response?

1. Do not rub the eye; flush it thoroughly with running water, wash the hands with soap, and see an eye doctor if pain or redness persists
2. Rub the eye well to scrape out the hairs, use over-the-counter eye drops, and watch
3. Apply human steroid ointment to the rash on the hand and wait for the eye to heal on its own
4. Close the eye and sleep until the pain fades, and reconsider if it has not improved by morning

AnswerA. Do not rub the eye; flush it thoroughly with running water, wash the hands with soap, and see an eye doctor if pain or redness persists

ExplanationThe urticating hairs of New World tarantulas are fine and barbed; in the eye they lodge in the cornea, cause severe inflammation, and can affect vision if neglected. The correct answer is not to rub the eye, flush it thoroughly with running water, wash the hands with soap to remove the hairs, and if pain or redness persists see an eye doctor and tell them urticating hairs may be in the eye. Rubbing pushes the hairs deeper into the cornea and makes it worse. Over-the-counter eye drops do not remove the hairs. Rather than self-applying human ointment, see a dermatologist if the dermatitis spreads. Leaving it until morning lets keratitis progress. In future, always wear gloves and goggles for work inside the enclosure, and stop work as soon as the animal starts rubbing its abdomen.

IssuesDespite knowing the danger of New World tarantula hairs, the owner worked inside the enclosure without goggles or gloves. They did not stop even when the animal gave its warning by rubbing its abdomen. The family did not know what to do when hairs get in the eye.

ImprovementWear gloves, goggles and long sleeves for work inside the enclosure, and do it only after confirming the animal is inside its shelter. If it starts rubbing its abdomen, close the lid and stop. Share the response to urticating hairs, "don't rub, flush with running water, see an eye doctor," with the family, and set up a place to rinse the eyes near the work area.

Sunday morning. The plastic container of crickets you stocked up on as feeders gives off a strong smell; dead crickets and droppings have piled up on the bottom and tiny white bugs are moving about. You were planning to take crickets from it to feed your scorpion. The scorpion itself is fine, but the feeder container sits next to the kitchen sink and has not been cleaned for over two weeks.

What is the most appropriate response?

1. The scorpion is healthy, so just take the live crickets and feed them as they are
2. Remove only the dead ones and keep using the live crickets as they are
3. Remove the dead crickets and soiled bottom, wash the container, move only healthy crickets to a separate container, and keep the feeder container away from the kitchen
4. Spray deodorizer in the container to kill the smell, then feed from it

AnswerC. Remove the dead crickets and soiled bottom, wash the container, move only healthy crickets to a separate container, and keep the feeder container away from the kitchen

ExplanationAn unsanitary feeder container breeds nematodes, mites and bacteria, and crickets taken from it spread parasites and disease to the animal. Kept next to the kitchen sink, it also becomes a source of infection for people. The correct answer is to remove the dead crickets and soiled bottom, wash the container, move only healthy crickets to a clean separate container, and keep the feeder container away from the kitchen. Even if the scorpion is fine, contaminated prey causes mouth mites and refusal to eat. Removing only the dead ones leaves the container contaminated. Deodorizer residue sticks to the crickets, transfers to the scorpion, and causes poisoning. Clean the feeder container every few days, remove dead ones daily, and give the crickets food and water to keep them healthy.

IssuesThe feeder container went uncleaned for over two weeks and sat next to the kitchen sink, close to food. The owner did not understand that the health and hygiene of feeder insects directly affect the animal's health and the family's safety.

ImprovementClean feeder containers every few days and remove dead insects daily. Keep them in a well-ventilated spot away from the kitchen and food. Stock no more than 1–2 weeks' supply, and give the crickets vegetables and water to keep them healthy. Wash hands thoroughly after handling the feeder container too.

Night. While changing the water dish, the scorpion's stinger got through a gap in your glove and into your fingertip. The sting site hurts intensely, and within minutes the finger began to go numb. The species is considered moderately venomous. Family members suggest "suck the venom out with your mouth" and "tie the finger off tightly." The animal is back in its enclosure.

What is the most appropriate response?

1. Suck hard on the wound with your mouth to draw the venom out
2. Tie a cord tightly around the base of the finger to stop the venom spreading
3. Cut the wound open and squeeze the venom out with the blood
4. Wash with running water and soap, cool it, contact a medical facility and give the species name, and watch the spread of numbness and swelling and any change in breathing

AnswerD. Wash with running water and soap, cool it, contact a medical facility and give the species name, and watch the spread of numbness and swelling and any change in breathing

ExplanationFor a scorpion sting, wash the wound with running water and soap and cool it; once numbness or swelling appears, contact a medical facility, give the species name and venom information, and get seen. Keep the stung hand still and not below heart level, and call an ambulance for breathing difficulty, widespread hives or dizziness. Sucking with the mouth absorbs venom through the oral mucosa and contaminates the wound with no benefit. A tight tourniquet cuts off blood flow, causing tissue death, and releasing it sends venom spreading suddenly. Cutting the wound invites infection and bleeding. The animal is safely in its enclosure, so deal with the person first. When seen, give the species, the time of the sting and the course of symptoms.

IssuesDespite keeping a venomous species, the owner worked in a position where the stinger could get through a gap in the glove while changing the water dish. The family did not know the correct response to a sting and proposed wrong measures: sucking, tying off and cutting.

ImprovementDo enclosure work only after moving the animal to a separate container with a cup, using thick gloves and long tools. Write the response to stings and bites, "wash, cool, medical care, ambulance for breathing difficulty," on paper and post it by the enclosure. Prepare a card with the species name and venom status to bring when seeking care.

Late at night, while feeding your giant centipede, it bit the back of your hand through the glove, sinking in its forcipules, and will not let go. The pain is intense and you badly want to shake it off. The animal is outside the enclosure, on the table. A family member is reaching out, saying "grab it and pull it off."

What is the most appropriate first action?

1. Shake the hand hard to fling the animal off
2. Have the family member grab the animal and pull it off
3. Stay still and wait for it to let go on its own; if it does not, blow on it or lower the hand onto the table so it releases
4. Put the hand under the tap as it is and wash the animal off with water

AnswerC. Stay still and wait for it to let go on its own; if it does not, blow on it or lower the hand onto the table so it releases

ExplanationShaking off or pulling off a biting animal drives the forcipules deeper, injects more venom, and damages the animal's forcipules and body. The correct answer is to stay still and wait for it to let go on its own; if it does not, blow on it or lower the hand onto the table to prompt it to walk off. Once it releases, cover it with a cup, return it to the enclosure, and wash the wound with running water and soap and cool it. Shaking the hand makes the animal fall and get injured, and it may flee the table and escape. A family member pulling it off invites a second bite to them. Washing it off under the tap can drop the animal into the drain and lose it, and if it stays attached the wound deepens. Seek medical care for swelling or numbness, and call an ambulance for breathing difficulty.

IssuesFeeding was done with the animal outside the enclosure, a high-risk way of handling it. The family did not know the rule for bites, "don't shake it off, don't pull it off," and nearly caused a second accident in a panic.

ImprovementFeed inside the enclosure with long tongs and never take the animal out. Share the bite response, "stay still and wait, blow on it, lower onto a surface, recover with a cup, wash and cool," with the family. Use thick gloves, and always have two people for centipede work, one responsible for recovery.

9 p.m. Your husband, helping clean the enclosure, was bitten by the tarantula. About 15 minutes after washing the wound under running water, hives have spread over his whole body and he says his throat feels tight and he is short of breath. His face is swelling too. He has previously had a bad swelling reaction to a bee sting. The animal is back in its enclosure.

What is the most appropriate first action?

1. Call 119 (ambulance) immediately, lay him down with his legs raised, and watch his breathing while waiting for the paramedics
2. Give him an over-the-counter antihistamine and watch for 30 minutes
3. Have him drive himself to the hospital in the family car
4. Keep cooling the wound; it will settle, so rest indoors until symptoms subside

AnswerA. Call 119 (ambulance) immediately, lay him down with his legs raised, and watch his breathing while waiting for the paramedics

ExplanationWhole-body hives, facial swelling, throat tightness and breathing difficulty after a bite is anaphylaxis, which can close the airway and cause cardiac arrest within minutes. The correct answer is to call 119 (ambulance) immediately, lay him down with his legs raised, and watch his breathing and consciousness while waiting for the paramedics. If breathing is hard, a sitting-up position is also acceptable. If he has been prescribed an epinephrine auto-injector (EpiPen), use it. Watching for 30 minutes on over-the-counter medicine lets the airway obstruction progress. Driving himself risks losing consciousness on the way, and transport by car delays paramedic treatment. Cooling the wound does not stop a systemic reaction. People with a history of bee sting reactions are at higher risk of allergy to arthropod venom, so check before letting them help with care work.

IssuesA family member with a history of bee sting swelling was allowed to help clean a venomous animal's enclosure. The owner did not know that signs of anaphylaxis (whole-body hives, breathing difficulty) are the trigger for calling an ambulance, and the initial response was nearly delayed.

ImprovementDo enclosure work only after moving the animal to a separate container, and do not let family members with allergy history take part. Post the things to watch after a bite and "hives or breathing difficulty means call 119 without hesitation" by the enclosure. Know the family's allergy history and, if needed, consult a doctor about prescribing an epinephrine auto-injector.

Morning. Your tarantula (adult) is outside its shelter, curled up small with its legs folded under its body, not moving. When you blow on it, the legs seem to move slightly. The abdomen is somewhat shrunken. The water dish has been empty for three days. Your wife says "if it's dead, let's bury it," and you, unable to tell, are thinking of shaking it to check.

What is the most appropriate response?

1. Curled legs are a sign of death, so bury it as it is
2. Shake the enclosure hard to check for a response, and declare it dead if it does not move
3. It responds so it is fine; feed it as usual and watch
4. It responds, so treat it as dying: move it to an ICU container with damp paper and shallow water, bring its mouth to the water, and observe for 24 hours without touching

AnswerD. It responds, so treat it as dying: move it to an ICU container with damp paper and shallow water, bring its mouth to the water, and observe for 24 hours without touching

ExplanationThe death curl, legs folded under the body, is a sign of a dying animal, not death, and if the legs move when you blow on it, it is alive. A dead animal lies with its legs limp and stretched out, motionless. The empty water dish and shrunken abdomen point to dehydration, so the correct answer is to move it to an ICU container (damp paper towel + shallow water dish), bring its mouth to the water so it can drink, keep it dark and quiet, and observe for 24 hours without touching. Burying it in this state kills a living animal. Shaking the enclosure further exhausts a weakened animal and damages the exoskeleton. It cannot eat, and live prey would attack it. If there is no recovery by the next day, consult a specialist shop or an invertebrate clinic that same day.

IssuesThe water dish was left empty for three days, causing dehydration, and the owner did not know the difference between a death curl and death. They had not prepared how to check for life (blow on it and watch for a response, look at the leg posture) or the ICU container as a lifesaving measure.

ImprovementCheck and change the water dish every 2–3 days without fail. Share with the family how to tell life from death (death curl means dying; legs stretched out and motionless means dead). Keep ICU container materials (small container, paper towel, shallow dish) beside the enclosure and practice setting it up.

Evening. You need to drive your tarantula (adult), which has a cracked abdomen, to an invertebrate clinic 40 minutes away by car. It is midsummer and the car is hot. You have a large enclosure, a small plastic container with lid, paper towels, ice packs and towels. Your wife says "let's put the big enclosure on the passenger seat and hold it on my lap."

What is the most appropriate transport method?

1. Carry it in the large enclosure, substrate and all, on the passenger seat
2. Scoop it by hand into a small sealed container and place it by the window in direct sunlight
3. Move it with a cup into a small sealed container lined with damp paper, wrap it in a towel to darken it, and drive with the air-conditioning on without shaking it
4. Carry it in a lidless container on a lap so you can watch the wound on the way

AnswerC. Move it with a cup into a small sealed container lined with damp paper, wrap it in a towel to darken it, and drive with the air-conditioning on without shaking it

ExplanationThe rules for transport are "small sealed container lined with damp paper, dark, avoid temperature changes, no shaking, keep it short, no bare hands." The correct answer is to move the animal with a cup into a small container, wrap it in a towel to keep it dark, and secure it on a seat in a car with the air-conditioning on. Do not put ice packs directly against the container; use them to manage the car's temperature. In a large enclosure the animal moves and hits the walls, and substrate sticks to the wound and worsens it. Scooping by hand widens the damage, and a midsummer window seat exceeds the danger zone in minutes. A lidless container risks escape, and on a lap vibration transmits directly. Phoning ahead with the species, venom status, temperature and humidity, last molt date and feeding records speeds up the exam.

IssuesThe owner did not know in advance how to transport an animal leaking fluid and nearly chose to carry it in its enclosure, a method with heavy vibration and temperature change. They also did not anticipate how hot a car gets in midsummer.

ImprovementKeep a "transport kit" ready: a small sealed container, paper towels, a towel and ice packs. Look up invertebrate clinics in advance and know the route and travel time. Keep the information to give on transport (species, venom status, temperature and humidity, last molt date, feeding records) together in a logbook.

Saturday, 11 p.m. Your tarantula (adult female) began molting four hours ago and has stopped moving with half its legs still in the old skin. You searched for a nearby clinic that sees invertebrates but found none open at night, and the specialist shop you bought it from is closed. You posted photos on social media and are waiting for answers, but there are no replies. Humidity is 60% and the enclosure is at 24°C.

What is the most appropriate response?

1. Leave the animal as it is and sleep until morning while waiting for replies on social media
2. Take it to an emergency (after-hours) animal hospital for dogs and cats and have them peel off the old skin
3. With no replies coming, follow a video and peel off the old skin yourself in one go
4. Raise the humidity and keep it dark, limit yourself to softening the old skin with a damp cotton swab, and contact the specialist shop or an invertebrate clinic first thing in the morning

AnswerD. Raise the humidity and keep it dark, limit yourself to softening the old skin with a damp cotton swab, and contact the specialist shop or an invertebrate clinic first thing in the morning

ExplanationWhen no specialist is reachable at night, the safe measures available to an owner are to raise the humidity, keep it dark and not touch, and, if old skin remains after several hours, limit yourself to softening it with a damp cotton swab. Do not force it off; contact the specialist shop or an invertebrate clinic first thing in the morning for instructions. Waiting for social media replies and doing nothing means neither raising the humidity nor treating it. A dog-and-cat after-hours hospital has no experience with invertebrate molt problems, may worsen things with inappropriate treatment, and the vibration and temperature change of transport are an added burden. Peeling the skin off yourself in one go after a video is the most dangerous option, leading to lost legs, fluid loss and death. If it still cannot move by the next morning, treat it as an emergency and contact them as the top priority.

IssuesThe owner had not checked, when starting out, for invertebrate clinics and specialist shops, their contacts, or whether any offered nighttime help, leaving social media as the only resort in an emergency. Pre-molt humidity of 60% was on the low side and raised the risk of an incomplete molt.

ImprovementBefore keeping the animal, find several invertebrate clinics and specialist shops and record their hours and whether they take nighttime calls. When molt signs appear, keep humidity on the high side for the species and be ready to watch before the molt starts. Write the safe measures for a molt problem (humidity, darkness, softening with a cotton swab only) on paper and post it by the enclosure.
