Is a Desert Hairy Scorpion Right for You?

Desert Hairy Scorpions are a great choice for those interested in observing natural behaviours like burrowing, hunting, and thermoregulating. They are low-maintenance but do require a well-thought-out desert terrarium setup.

Pros

• Fascinating natural desert behaviours

• Hardy and long-lived

• Low-maintenance once enclosure is established

• Impressive appearance and size

Cons

• Defensive and easily stressed by handling

• Fast-moving and difficult to control during maintenance

• Requires a dry, heated habitat

• Not suitable for beginners with no experience in invertebrate care

Housing Requirements

A proper enclosure setup is key to mimicking their natural arid habitat.

Enclosure

• A 40–60 litre terrarium with a secure, ventilated lid is suitable for one adult

• Floor space is more important than height

• Use a locking lid to prevent escapes, as they are strong diggers and climbers

Substrate

• Use a deep layer (15–20 cm) of a sand/soil mix (play sand mixed with clay or excavator clay)

• The substrate should be dry but compact enough to allow burrowing

• Provide rocks or cork bark pieces to create secure hiding areas

Temperature and Humidity

• Temperature: Maintain 28–32°C (82–90°F) during the day, with a slight drop at night

• Use a heat mat or overhead heat source—always regulated with a thermostat

• Humidity: Keep low, around 30–40%

• Avoid misting; instead, provide a very shallow water dish

Lighting

• No special lighting is required

• Scorpions are nocturnal and prefer dim conditions

• A red or blue night-time viewing light can be used to observe activity

Feeding and Diet

Desert Hairy Scorpions are insectivores and active hunters.

Recommended Foods

• Crickets

• Dubia roaches

• Locusts

• Occasional waxworms or mealworms

Feeding Schedule

• Adults: once or twice per week

• Juveniles: every 2–3 days

• Do not overfeed; remove uneaten prey after 24 hours

Water

• Provide a small, shallow dish of fresh water at all times

• Clean and refill daily, even though they may rarely use it

Behaviour and Handling

Desert Hairy Scorpions are not docile and are best left undisturbed.

• They are defensive and may raise their pincers or strike with their tail if provoked

• Handling is not recommended; stress can lead to injury or defensive behaviour

• Use long soft-tipped tongs or a container for moving them during enclosure cleaning

Cleaning and Maintenance

• Spot clean regularly to remove uneaten prey and faeces

• Replace substrate every 4–6 months or as needed

• Avoid introducing excessive moisture during cleaning

• Wash and disinfect decor pieces occasionally with reptile-safe products

Health and Common Issues

Signs of a Healthy Scorpion

• Actively burrowing or hiding

• Eating regularly

• Glossy exoskeleton without injuries or deformities

Common Issues

• Dehydration: Even desert species need access to water; watch for shrivelled appearance or sluggish behaviour

• Mould or mites: Can occur if humidity is too high; maintain proper ventilation

• Improper moults: Rare, but can be fatal; avoid disturbance during moulting

Legal and Ethical Considerations

• Ensure your scorpion is captive-bred and sourced from a reputable breeder or exotic pet shop

• Wild collection is harmful to native ecosystems and may be illegal in some regions

• Check your local and national regulations regarding the keeping of exotic invertebrates

Desert Hairy Scorpion vs Other Species

If you're comparing the Desert Hairy Scorpion to other commonly kept species, here are a few distinctions:

• Compared to Emperor Scorpions: Desert Hairy Scorpions are more defensive, prefer dry conditions, and are less tolerant of handling

• Compared to Asian Forest Scorpions: Both are defensive, but Desert Hairy Scorpions are faster and live in arid rather than humid habitats

• Unique Traits: Sandy yellowish colouring, extremely hairy legs (for sensing vibrations), strong burrowing instinct

Final Thoughts

Desert Hairy Scorpions are incredible pets for the right type of keeper. Their size, behaviour, and hardiness make them a popular choice among more experienced invertebrate enthusiasts. However, they are not interactive pets and are best suited to those who enjoy watching natural behaviours in a secure, well-maintained habitat.

If you’re prepared to respect their space and recreate their natural desert environment, a Desert Hairy Scorpion can be a truly fascinating and rewarding addition to your exotic animal collection.
