Care guide
Red Fang Wandering Spider
Piloctenus haematostoma
A fast, defensive African wandering spider with a strikingly red face and fangs, reaching roughly 3-4 inches in legspan. Its venom has never been rigorously studied in the medical literature, and given its family (Ctenidae) includes some of the most medically significant spiders in the world, that uncertainty alone earns it top-tier caution. This is NOT a tarantula.

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.
Quick Snapshot
| Temperature | 72-78°F |
|---|---|
| Humidity | High (70-80%) with cross ventilation; damp substrate, dry climbing surfaces and den |
| Setup Type | Semi-arboreal, humid, height over depth |
| Substrate | Coco fiber, 1-2 in, with cork bark or branches for climbing |
| Feeding | Crickets/dubia up to 1 in |
| Care Difficulty | Spice 5: Extreme (Medical Significance, precautionary) |
| Handling | NEVER |
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
- Baby Buddy for slings
- Tall custom terrestrial with climbing surfaces for adults
Warnings First
- Venom is not well-characterized in the medical literature; treated as potentially medically significant out of caution given its family includes Phoneutria, among the most dangerous spiders known
- Fast and defensive, readily stands and displays rather than fleeing
- No urticating hairs: a threat display can escalate straight to a bite
- Real escape risk; agile climber as well as a runner
- Misting every other day only works because of the cross ventilation. Vent low on one wall and high on the opposite wall or the den stays permanently damp.
Simple Care
- Provide vertical climbing structure: not a strict ground-dweller.
- Vents low on one wall and high on the opposite wall so air rises past the cork and dries it between mistings.
- Keep humidity consistently high with light misting every other day.
- Shallow water dish with pebbles in it so spiderlings cannot drown, so you are not relying on misting alone.
- Tools only for all maintenance, no bare-hand contact.
Advanced Keeper Notes
Enclosure & Microclimate
- This species wants height and climbing surfaces more than substrate depth: cork bark rounds or leaned branches let it establish a den off the ground the way it would in a tree hollow or under forest-floor debris.
- Humidity needs to stay in the 70-80% range fairly consistently; light misting every other day with good cross-ventilation keeps it from drying out without fostering mold.
- Make that cross-ventilation diagonal to suit the enclosure: vents low on one wall and high on the opposite wall, so air enters across the damp substrate, rises past the cork, and exits above the den. A tall enclosure vented only at the top stratifies, leaving warm damp air sitting in the upper third which is exactly where this species builds its den. Misting every other day into a stratified enclosure gives you a permanently wet den rather than consistent humidity.
- Ventilation and ambient humidity trade against each other, and the misting schedule is only safe because the airflow carries the excess off. If the cork is still damp when you next mist, add airflow rather than misting less.
- Judge by touching the cork rather than by a gauge. Substrate damp with no free water, cork rounds and branches dry to the touch between mistings, no persistent condensation on the upper glass.
- Keep a shallow water dish with pebbles or coarse grit so the waterline sits below the rim. On a fast, defensive spider with poorly characterized venom, a permanent safe water source means fewer reasons to open the enclosure for extra misting runs, and spiderlings drown in open dishes.
- Mist the substrate and the base of the cork rather than the den itself. Moisture rises through moving air to reach the animal while the den and the climbing surfaces stay dry and grippy.
Feeding, Growth & Maintenance
- Feeding: crickets or roach nymphs no larger than 1 inch, juveniles every 5-7 days, adults every 10-14 days. It's an active pursuit hunter and readily takes moving prey.
- Maintenance: pull anything uneaten after 24 hours since stray feeders can trigger unnecessary stress. Watch closely for pre-molt signs (dulled coloration, reduced appetite) and suspend feeding at the first signs, given how little is documented about this species around molting.
Possible Origin / Range
- Likely native range: West/Central Africa, Guinea per current wholesale sourcing.
- Habitat translation: Humid tropical forest floor and understory: replicate with high humidity, moderate warmth, and vertical climbing structure rather than a dry desert-style setup.
Advanced Keeper Details
- Given the genuine gap in venom research for this species, keep it off any 'handleable' or 'beginner-friendly' messaging entirely: any customer inquiry about handling should get a direct no.
- Formerly sold under the informal name 'Ctenus sp. Red Fang' before reclassification; some specialist sellers still hedge with 'cf. haematostoma.'

Recommended Big Z's Setup
- Baby Buddy for slings
- Taller enclosure (min. ~10 in) with climbing surfaces for adults: this species is semi-arboreal and needs vertical height more than substrate depth, so Burrow Buddy's depth-oriented design doesn't suit it well
