Piloctenus haematostoma
Red Fang Wandering Spider: Advanced Care Guide
Keeper Snapshot: A fast, defensive wandering spider with a bold red face, closely related to some of the world's most dangerous spiders. Its own venom is unstudied, so it's treated as medically significant. No handling, display only.

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.

Humidity zones: Very Low under 30% - Low 30-60% - Low-Moderate 40-70% - Moderate 60-80% - Moderate-High 70-85% - High 80%+ - Very High 90%+
Enclosure Format / Size Class
- Slings: Baby Buddy with secure ventilation and climbing surfaces.
- Adults: tall enclosure, 10+ in, with cork or branches for climbing and a pebble-filled dish.
Warnings First
- Treated as medically significant: closely related to some of the world's most dangerous spiders, and its own venom has never been characterized.
- Treat any bite as a medical emergency and get care right away.
- Fast and defensive. It stands its ground and displays rather than fleeing, and a threat display can go straight to a bite.
- No urticating hairs on this species, so there's no lesser defense between a display and a bite.
- Real escape risk: an agile climber as well as a fast runner. Secure every gap.
- Tools only for every enclosure job. No bare-hand contact.
Simple Care
- Give it vertical climbing structure; it wants height, not just floor space.
- Vent low on one wall and high on the opposite so air rises past the cork and dries it between mistings.
- Keep humidity consistently high with a light mist every other day.
- Keep a shallow water dish with pebbles so spiderlings can't drown.
- Tools only for all maintenance. No bare-hand contact.
- No handling. Treat any bite as a medical emergency.
Advanced Keeper Notes
Enclosure & Microclimate
- Wants height and climbing surfaces more than substrate depth: cork rounds or leaned branches let it den off the ground.
- Hold humidity around 70-80% with a light mist every other day and strong cross ventilation so it doesn't stay wet or grow mold.
- Vent low on one wall and high on the opposite so air crosses the damp substrate, rises past the cork, and exits above the den.
- Judge by touching the cork, not a gauge: substrate damp with no free water, cork and branches dry between mistings.
- Mist the substrate and base of the cork, not the den itself, so the climbing and molting surfaces stay dry and grippy.
Feeding, Growth & Maintenance
- Crickets or roach nymphs no larger than 1 in. Juveniles every 5-7 days, adults every 10-14 days.
- It's an active pursuit hunter and readily takes moving prey.
- Remove uneaten prey after 24 hours. Watch for premolt signs (dulled color, reduced appetite) and stop feeding at the first sign.
Possible Origin / Range
- Likely native range: West and Central Africa, in the Guinea region.
- Habitat translation: Humid tropical forest floor and understory: high humidity, moderate warmth, and vertical climbing structure, not a dry desert-style setup.
Advanced Keeper Details
- Keep it off any handleable or beginner-friendly messaging. Any question about handling gets a direct no.
- Sometimes still labeled by an older informal name in the trade; always treat it as this species for care purposes.
