Use This Guide Safely
- Confirm the exact animal. Match this guide to the species, locality, size, and life stage on your label. If the ID is uncertain, use the more conservative part of the range and ask before changing the setup.
- Change one thing at a time. Treat temperature and humidity as target zones, then watch posture, burrowing, drinking, feeding, and molt behavior before making another adjustment.
- Respect the handling boundary. If the guide says no handling, fast, defensive, or medically significant, plan transfers with catch cups, locked lids, and no bare hands. For serious bites, stings, or symptoms, seek emergency medical care.

Enclosure Format / Size Class
- secure sling setup
- juvenile burrow grow-out
- adult fossorial setup with 8+ in of moisture-holding substrate
Warnings First
- Fast and defensive when exposed
- Old World bite risk; no handling
- Needs humidity but also ventilation
- Do not cohabitate
- 'Humidity but also ventilation' resolves as cross ventilation at the substrate line: humid deep layers, moving air above them.
Simple Care
- Give depth, moisture, and a starter burrow.
- Cross ventilation low on two opposite walls, at the substrate line; this is how you get humid without stagnant.
- Water dish with pebbles in it so slings cannot drown.
- Keep the lid secure before opening any maintenance path.
- Feed at the burrow entrance and remove leftovers.
Advanced Keeper Notes
Enclosure & Microclimate
- Deep, moisture-holding substrate is the foundation. The animal should be able to disappear completely into a tunnel system.
- Keep the lower layers humid and the airflow good. Stagnant wet air grows mold. Dry substrate gives bad molts. You have to solve both.
- Anchor cork and decor before adding substrate so tunnel collapse is less likely.
- That balance between mold and bad molts is decided almost entirely by where the vents sit. Put them low on two opposite walls, right at the substrate line, so air crosses the top of the humid column and keeps the tunnel system connected to fresh air. Vent only through the lid and you get both failure modes at once: a drying surface that causes molt problems over a stagnant, saturated burrow that grows mold.
- Ventilation and ambient humidity are one system, with the substrate as the moisture source rather than the air. Hold 70 to 80% by keeping the lower layers humid and running a dish, under vents that flow freely. Never seal the enclosure to hold the number.
- Judge by the substrate rather than a gauge. Lower layers damp enough to hold a tunnel without weeping water, surface allowed to look drier. A sour smell or persistent condensation means more airflow, not less water.
- Keep the dish full and put pebbles or flat stones in it so the waterline sits below the rim. Slings drown in dishes, and on a fast, defensive burrower a dish that is safe by construction means fewer reasons to open the enclosure.
- Hydrate down one side or at the burrow entrance rather than misting the surface. That keeps the humid microclimate in the tunnel system where the spider lives and leaves the surface free to dry and re-air.
Feeding, Growth & Maintenance
- Use roaches or crickets sized safely to the spider. Feed near the burrow entrance, not by poking tools inside.
- Molting: sealed burrow, fasting, or webbed-over entrance means leave it alone. Remove any loose feeder and wait for the spider to reopen before feeding.
- Spot-clean what is visible. Do not tear apart the whole burrow for routine maintenance.
Possible Origin / Range
- Likely native range: West and Central African humid forest and forest-edge habitats, especially Cameroon region.
- Habitat translation: Warm humid fossorial build with deep stable substrate, cork structure, and strong containment.
Advanced Keeper Details
- Hysterocrates species are often mislabeled in trade. Treat care as a large humid West African fossorial group unless the breeder confirms species identity.
- Some keepers report water-associated behavior, but captive success still comes from humid substrate and a safe water dish, not an aquatic setup.
- Rehousing should be tub-in-tub, planned, and calm. Exposed baboons move fast and escalate quickly.
