The Care and Maintenance of the Emperor Scorpion 

Pandinus imperator
Difficulty Level: Beginner

The Emperor Scorpion, scientifically known as Pandinus imperator, is one of the most popular scorpions in the world, and they are one of the first species many people imagine when they hear the word “scorpion.” These are large scorpions, but they are a lot more manageable than their intimidating appearance might suggest.
In the wild, Emperor Scorpions are found in the warm, humid forests of West and Central Africa. They spend much of their time hiding under fallen logs, rocks, or leaf litter, or in burrows they dig, where they can find a dark, damp, stable environment. They are nocturnal predators, so instead of sight, they rely on vibration and touch to locate and subdue prey.
Recreating those conditions in captivity means focusing on deep, moisture-retentive substrate, stable humidity, secure hides, and a setup that allows them to dig and retreat when they want to hide.


Natural History, Description, and Related Species

Pandinus imperator belongs to the family Scorpionidae and is one of the largest scorpions commonly kept as a pet. Adults can reach up to 8 inches in total length, with a heavy body and large, rounded claws.
Their usual coloration is dark brown or black, though some individuals may show brown, reddish-brown, or slightly greenish tones under certain lighting. The pedipalps are big, and that is why Emperor Scorpions are much more likely to pinch than sting when threatened.
Their venom is considered mild compared to the smaller, medically significant scorpions. A sting will still hurt, and individual reactions can vary. Anyone with allergies or sensitivity to venomous animals should be especially cautious.

CITES Status, Wild Collection, and Ethical Sourcing

Emperor Scorpions are listed under CITES Appendix II. CITES stands for the Convention on International Trade in Endangered Species of Wild Fauna and Flora. In simple terms, it is an international agreement that regulates wildlife trade so species are not collected from the wild in excess. This does not mean Emperor Scorpions are illegal to own or that they can never be imported. It means international trade must be legal, documented, and properly permitted.
This species ended up on CITES because of heavy demand from the pet trade. For years, many Emperor Scorpions were collected and exported from West Africa because they were impressive and easy to sell to beginners.
That is why sourcing matters when it comes to this species. Captive-bred Emperor Scorpions should always be the preferred option. They are already adapted to captive life and do not add unnecessary pressure to wild populations.
That said, not all wild-caught or field-collected animals are the same. A dealer importing legally with proper CITES permits is different from someone who poaches and smuggles. Legal trade can exist, but captive-bred is still the better choice whenever it is available.
If you are buying an Emperor Scorpion, ask the dealer where their scorpion came from. Captive-bred is ideal, but properly documented, legally imported animals are your next best option. If the dealer gives you vague answers, has suspiciously cheap animals, and/or can’t/won’t tell you where their scorpions are sourced, you should recognize the red flags and avoid purchasing any live animals from that source.

Emperor Scorpion vs. Asian Forest Scorpion

Emperor Scorpions are often confused with Asian Forest Scorpions. Both are large, dark scorpions with massive claws that are fairly common in the pet trade. But they are definitely not the same animal.
The Emperor Scorpion, Pandinus imperator, comes from West and Central Africa, while the Asian Forest Scorpions, Heterometrus spp., come from tropical parts of Asia. Emperor Scorpions have a heavier, broader build with larger, rounder claws. Asian Forest Scorpions are often a little more streamlined, though this can vary depending on the species.
Temperament is usually the biggest difference for keepers. Emperor Scorpions are generally calmer, slower, and more likely to pinch before they sting. Asian Forest Scorpions are often more defensive, quicker to posture, and more likely to strike or sting when disturbed.
Venom in both scorpions is generally not considered medically significant for healthy adults, but both can deliver painful stings.
Price and availability are also different and usually a dead giveaway. Asian Forest Scorpions are cheaper and easier to find. Emperor Scorpions are more expensive because they are CITES-regulated, imports require documentation, and true captive-bred animals take time and effort to produce.
Both can make interesting captive animals, but they should not be treated as interchangeable.

Recommended Supplies for an Emperor Scorpion

Because this species needs humidity and burrowing opportunities, the enclosure should focus on moisture retention, cover, and security.

Enclosure Size & Setup

Emperor Scorpions are terrestrial and burrowing, so floor space and substrate depth are more important than height.

Scorplings

  • Enclosure: Small secure acrylic enclosure or deli cup style setup
  • Substrate Depth: 2 to 3 inches of moist Terra Aranea
  • Humidity: Keep substrate slightly damp, not swampy
  • Decor: Small cork bark hide, leaf litter, light sphagnum moss

Scorplings should not be kept in overly large enclosures. They need security, stable moisture, and easy access to prey.

Juveniles

Juveniles may dig, hide, or spend long periods underground. This is normal, so don’t worry.

Adults

Avoid tall, arboreal enclosures. They don’t need climbing height and the vertical space only adds risk of your scorpion getting hurt from falling.

Substrate & Humidity

Emperor Scorpions need a humid setup with substrate that holds moisture and burrows without being saturated.

  • Keep substrate consistently damp
  • Do not allow the entire enclosure to dry out, provide a gradient
  • Provide a full water dish at all times
  • Add leaf litter and sphagnum moss to help hold pockets of humidity
  • Avoid swampy, stagnant conditions

Terra Aranea works well because it holds moisture and supports burrowing. Leaf litter and sphagnum moss help create a more stable surface layer and give the scorpion more cover.

The goal is damp, not flooded or swampy.

Temperature & Lighting

  • Maintain temperatures between 74 and 82°F
  • Avoid overheating
  • No direct heat lamps are necessary
  • If supplemental heat like a heat pad is used, place it on the side of the enclosure and always use a thermostat
  • Lighting is only needed for plants or display
If you use live plants, low-output LED or fluorescent lighting can be used on a timer. Make sure the scorpion has hides, plant cover, and shaded areas so they can avoid the light when they want to.
Emperor Scorpions are also UV reactive, which means they glow a bright blue-green under blacklight. This is one of the coolest things about scorpions, but it is not magic, and it is not a reason to keep a UV light over the enclosure. The glow is fluorescence, caused by compounds in the outer cuticle that absorb ultraviolet light and re-emit it as visible blue-green light.
A handheld blacklight can be useful if you are trying to find the scorpion during maintenance or if you want to observe them briefly at night. Blacklights should be used sparingly because scorpions are nocturnal, and studies have shown that they react strongly to UV light. Prolonged UV exposure has also been shown to reduce the scorpion's fluorescence over time, which tells us that constant exposure is affecting the cuticle in some adverse way. So while it is cool to see them glow, don’t use a blacklight as their daily enclosure lighting, and don’t leave one running over the enclosure at night. Use it briefly and in moderation, then let the scorpion get back to the dark, humid environment they actually need. 

Feeding Schedule

Feeding should be based on body condition and appetite.

Scorplings

  • Frequency: Once or twice weekly
  • Prey: Pinhead crickets, small roach nymphs, or pre-killed prey pieces
  • Post Molt: Wait several days before feeding so exoskeleton hardens

Juveniles

  • Frequency: Every 5 to 7 days
  • Prey: Small crickets or roaches
  • Guidelines: Prey should be no larger than the scorpion’s body

Adults

  • Frequency: Every 7 to 14 days
  • Prey: Large crickets, roaches, or other appropriate feeder insects
  • Guidelines: Adjust based on body condition. If the sides look swollen, feed less often 

Remove uneaten prey within 24 hours, especially if the scorpion is in premolt or has recently molted.

Supplements

Scorpions do not require vitamin or calcium supplements. Feeder insects should be gutloaded with fresh fruits, vegetables, or a pre-made gutloading supplement for at least 24 hours before feeding.

Behavior & Handling

Emperor Scorpions are usually calm, but their temperament can vary between individuals. Some specimens are relaxed while others might be a little more defensive than most. Even a typically calm scorpion may change their temperament after a molt and suddenly be more defensive, or vice versa. You should always safely check your scorpion’s temperament with a small paintbrush or tongs before putting your hands in their enclosure or attempting to handle them.
As with all arachnids, handling is usually more dangerous for the animal than the handler. A fall from even a few inches could be enough to rupture your scorpion's exoskeleton, and this could be fatal. So, if you handle your Emperor Scorpion, sit down on the ground and hold them just off the floor, so if they were to bolt, they would not have far to fall. Always keep a catch cup handy anytime you are opening their enclosure, because they can surprise you with how fast they can climb up and bolt out of a terrarium.    
These scorpions are strong animals with powerful claws. If they feel threatened, they may posture, pinch, or even sting (rarely). While their venom is mild, their stinger is pretty big and shaped like the barb on a big fish hook. The damage to the skin most likely hurts more than any venom they inject.

A Note on Communal Keeping

Emperor Scorpions are sometimes described as being communal, and there are reports of multiple individuals sharing burrows in the wild. That does not mean I would recommend communal keeping as the standard setup for beginners. There is a big difference between several scorpions sharing space in a complex natural burrow system in the wild and several scorpions being placed together in a glass box in someone’s spare room. In captivity, space is limited, escape routes are limited, and stress can build quickly if one animal wants distance and cannot get it easily.
I have not personally kept this species communally, so I am not going to tell you it is something everyone should try. If an experienced keeper does attempt it, the enclosure should be much larger than a normal single-scorpion setup, with deep substrate, multiple hides and burrow starts, plenty of plants and visual barriers, and enough feeding opportunities that one scorpion is not constantly competing with another. Even then, there is always a risk of fighting, injury, cannibalism, or one animal slowly being outcompeted. That does not even mention the breeding and babies that can come from keeping them communally. For most keepers, especially beginners, keeping Emperor Scorpions individually is the safer and more responsible option.

Maintenance & Bioactive Considerations

A humid bioactive setup works very well for this species.

  • Keep water dish clean and full
  • Spot clean uneaten prey and waste if needed
  • Maintain damp substrate
  • Monitor for mold or stagnant air
  • Keep leaf litter topped off
  • Use springtails to help process waste. 

Because Emperor Scorpions need moisture, they are a much better candidate for bioactive setups than most desert scorpions. The key is to use tropical plants that do not require intense lights and provide hides so your scorpion doesn’t feel exposed and vulnerable. 

Common Issues

  • Dry Substrate: Can lead to dehydration, collapsed burrows and stress
  • Poor Ventilation: Can create stagnant conditions and mold
  • Overly Wet Substrate: Can cause unhealthy conditions, bacteria growth, mites, etc.
  • Misidentification: Asian Forest Scorpions are often sold or mistaken for Emperor Scorpions
  • Wild-Caught Stress: Field-collected animals may carry parasites or struggle to adjust

Final Thoughts

The Emperor Scorpion is one of the best beginner scorpions out there because of their temperament, hardiness, and looks. They have an awesome feeding response, and it is mesmerizing watching them move around their enclosure.
That is also one of the most frustrating aspects of keeping this species, because they can disappear for weeks or even months at a time. They might be in premolt. It might be a seasonal slowdown when temperatures drop. They may just not be hungry. Or, if it is a mature male, he may have only one thing on his mind, and that isn’t eating. It is also possible they are only coming out in the quiet of the night, and you’re asleep and just aren’t seeing them be active. But they may also shut the entrance to their burrow and not emerge for weeks for absolutely no discernible reason at all. If this happens, avoid the temptation to dig them up and check on them. This will not only needlessly destroy their burrow and stress them out, but you could also unknowingly be disturbing them while they are molting, which can be fatal. So be patient and only dig up the enclosure as a last resort. 
When these scorpions are out of their burrow, they do like to explore and move around a lot. They will dig up plants, flip water dishes, push rocks, and move dirt around like an excavator. This is something you will want to keep in mind when choosing their enclosure.
While the typical husbandry guidelines state that a 10-gallon aquarium is an appropriately sized enclosure for this species, I think that should be considered the bare minimum at best. Even though they probably will not use all the space every night, giving them a larger enclosure with a lot of floor space will give them the ability to express more of their natural behaviors, which will ultimately give them a better quality of life. You may see them less in a larger setup where they can have deeper and longer burrows, but when you do see them, it will most likely be a more amazing experience.
And while these scorpions are calm and generally slow-moving compared to other scorpion species, they can still move fairly quickly and can cover more ground than you would probably expect. They do not have the ability to climb the sides of glass or acrylic enclosures, but they can get enough of a grip on the silicone in the corners of glass enclosures to reach the lid. They are strong enough to pop off poor-fitting lids, so make sure your enclosure lid locks well and fits tightly, because they will wedge themselves out if given the chance.
Always keep a catch cup handy anytime you are opening their enclosure, because they can surprise you with how fast they can climb decor, use silicone corners, or hoist themselves over the edge if given the chance.
Overall, this is a fascinating animal, and they make for unique and interesting pets. Their care is easy, and these hardy scorpions are pretty forgiving of husbandry mistakes as long as you learn from them and avoid repeating them. If you are new to keeping scorpions, there probably isn’t a better species to introduce you to the hobby than the Emperor Scorpion.
