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
- bark-style micro setup for larger juveniles/adults
Warnings First
- Tiny spiderlings escape easily
- Over-misting can be dangerous
- Needs good light cycle
- Over-misting is dangerous mainly because most jumper enclosures are under-ventilated. Vent low on one wall and high on the opposite wall and the same misting becomes safe.
Simple Care
- Vertical space and anchor points matter.
- Vents low on one wall and high on the opposite wall so air rises past the hammock and dries the enclosure between mistings.
- Mist side wall lightly, not the spider.
- If you use a water dish, pack it with grit: a jumping spiderling drowns in almost nothing.
- Feed size-appropriate prey.
Advanced Keeper Notes
Enclosure & Microclimate
- Jumpers benefit from good room lighting or indirect natural light. Avoid overheating in direct sun.
- Provide upper anchor points where the spider can build a hammock. Do not destroy the hammock unless necessary.
- The over-misting warning is really a ventilation warning. A tall jumper enclosure with vents only in the lid stratifies: damp air rises and sits in the upper third, which is exactly where the hammock and the spider are. Put vents low on one wall and high on the opposite wall so air enters at substrate level, crosses the full height, and exits above the hammock. With that airflow, light wall misting dries back within a couple of hours and stops being risky.
- Ventilation and ambient humidity are one setting, and on a jumper you push it toward air. There is no humidity number to hold. Keep the substrate dry, mist one wall for drinking droplets, and let it dry fully between times.
- Judge by whether the enclosure dries rather than by a gauge. Walls clear within a couple of hours of misting, substrate dry, no persistent condensation. Condensation in a jumper enclosure is the warning sign.
- If you keep a water dish rather than relying on wall droplets, use a cap packed with grit so the waterline sits below the rim. Spiderlings drown in a few millimetres, which is why wall misting is the more common approach at small sizes.
- Mist the wall opposite the hammock rather than the hammock itself. The spider comes down to drink and its retreat stays dry, which is the microclimate arrangement that suits an animal that sleeps in a silk sac up top.
Feeding, Growth & Maintenance
- Hydration is best through tiny droplets on walls/decor. Avoid soaking the enclosure or trapping the spider in water.
- A compact, secure enclosure is excellent for small jumpers because it makes feeding and molt checks easier.
- Molting: a jumper seals itself into a thick silk hammock to molt and stops eating beforehand. Don't disturb the hammock, remove any feeders, and wait a few days after it emerges (until the new exoskeleton hardens) before offering prey.
Possible Origin / Range
- Likely native range: Southeastern United States and Caribbean subtropical habitats.
- Habitat translation: Bright ventilated arboreal microhabitat with perches, hides, and hydration droplets.
Advanced Keeper Details
- Hydration is critical; use tiny droplets or misting without soaking the enclosure.
- Track feeding by abdomen size and activity. Overfeeding females can shorten healthy display life.
