How To Care For Jumping Spiders: The Complete Husbandry Guide
Providing proper care for jumping spiders requires maintaining specific temperature and humidity gradients, offering appropriately sized live prey, and utilizing a vertical enclosure that accommodates their arboreal hunting behaviors. By replicating their natural microclimates and adhering to precise feeding schedules, keepers can successfully maintain these intelligent arachnids for their full lifespan.
Essential Preparation and Enclosure Requirements
Setting up a thriving habitat for a jumping spider, most commonly the bold jumping spider (Phidippus audax) or regal jumping spider (Phidippus regius), demands precise preparation of vertical space and environmental controls. Unlike ground-dwelling tarantulas, jumping spiders are arboreal hunters with exceptional eyesight, meaning their housing must focus on height rather than floor area, alongside ample visual barriers to reduce stress.
- Essential Equipment and Materials:
- Enclosure: Front-opening acrylic or glass terrarium with cross-ventilation, minimum dimensions of 8x8x12 inches (or a vertical conversion kit).
- Substrate: Coconut fiber, topsoil, or bioactive soil mix (1 to 2 inches) to help retain ambient humidity.
- Enrichment: Artificial foliage, cork bark rounds, twigs, and a magnetic or suction-cup hide placed near the top third of the enclosure.
- Climate Tools: Digital thermometer/hygrometer, ultra-low wattage heat mat (if ambient room temperature drops below 70°F), and a fine mist spray bottle.
- Prerequisite Knowledge:
- Understanding molting behavior (ecdysis), during which spiders spin a thick silken hammock and must not be disturbed or fed.
- Recognizing the signs of dehydration, such as a shriveled abdomen, versus correct hydration.
- Benchmarks:
- Estimated setup budget: Fifty to one hundred dollars.
- Setup duration: One to two hours for assembly and environmental stabilization.
Step-by-Step Husbandry and Maintenance Workflow
Step 1: Enclosure Assembly and Ventilation Optimization
Configure your vertical terrarium by securing cross-ventilation. Jumping spiders are susceptible to respiratory infections if air stagnates in high-humidity environments; ensure there is adequate airflow via perforated top or side panels. Layer the bottom with coconut fiber, plant fake vines or real terrarium-safe plants like pothos, and anchor vertical climbing structures spanning from the substrate to the ceiling.
Warning: Never use screen meshes made of hard metal or wide gaps that allow a small spiderling to escape or catch its delicate tarsal claws. Use fine nylon mesh if modifying lids.
Step 2: Environmental Monitoring and Climate Control
Maintain ambient temperatures between 72°F and 80°F during the day, allowing a slight drop of 5 degrees at night. Relative humidity should hover between 60% and 80%, depending on the specific species' geographic origin. Mist one side of the enclosure and the decor lightly once every day or two using distilled or reverse-osmosis water, allowing the droplets to form for the spider to drink directly.
Pro-Tip: Avoid heavy, soaking sprays that drench the substrate and cause mold blooms; jumping spiders prefer licking water droplets off surfaces rather than drinking from standing water dishes, which present drowning hazards.
Step 3: Feeding and Nutritional Management
Feed your jumping spider live prey scaled to its size. As a rule of thumb, the prey item should never exceed the length of the spider's body from the chelicerae to the spinnerets. For spiderlings, offer flightless fruit flies (Drosophila melanogaster or Drosophila hydei); for sub-adults and adults, switch to pinhead crickets, small mealworms, house flies, or small roaches.
- Introduce one live prey item into the enclosure using feeding tongs.
- Observe for 5 to 10 minutes to ensure the spider engages the prey.
- Remove any uneaten live insects after 15 minutes to prevent them from chewing on a molting spider.
- Adjust feeding frequency based on age: spiderlings eat every 2 to 3 days, sub-adults every 4 to 5 days, and mature adults every 7 to 10 days.
Step 4: Molting Management and Observation
Monitor your spider for behavioral changes indicating an upcoming molt, such as refusing food for several days, lethargy, and spinning a dense, opaque silken sac (hammock) near the top of the enclosure. During this period, cease feeding immediately. Mist the enclosure walls gently away from the hammock to maintain humidity without trapping excess moisture inside the web.
Warning: Never attempt to force-feed, handle, or tear open a molting web. A spider undergoing ecdysis has extremely soft, vulnerable new exoskeletons that harden over several days.

Common Husbandry Failures and Field Fixes
- Root Cause: Enclosure lacks vertical height and climbing complexity, leading to lethargy and unresponsiveness.
- Actionable Fix: Rearrange the terrarium layout immediately, adding magnetic hides, cork bark, and hanging foliage in the upper third of the enclosure where jumping spiders naturally spend 90% of their time.
- Root Cause: Mold and bacterial blooms forming on the substrate due to over-misting and poor airflow.
- Actionable Fix: Remove the moldy substrate patches, reduce misting volume, and introduce additional cross-ventilation holes drilled into the acrylic or glass frame.
- Root Cause: Premature handling or disturbing a spider during its vulnerable molting phase.
- Actionable Fix: Leave the enclosure completely undisturbed in a quiet, low-traffic area until the spider emerges on its own and its new exoskeleton darkens and hardens.
Frequently Asked Questions
How often should I mist my jumping spider's enclosure?
Mist one side of the enclosure once daily or every other day using distilled water. This allows the spider to drink the droplets while ensuring the air does not become permanently stagnant or waterlog the substrate.
Can jumping spiders live together in a communal enclosure?
No, jumping spiders are strictly solitary and cannibalistic. Housing multiple jumping spiders together will inevitably result in predation and the death of one or both specimens.
Why is my jumping spider refusing to eat?
Refusal to eat usually indicates that the spider is preparing to molt, is satiated from a previous large meal, or is stressed by incorrect temperature or humidity levels. Check your environmental parameters and look for a newly spun upper web hammock.
How do I distinguish between a male and female jumping spider?
Sexual dimorphism becomes apparent in sub-adult and adult stages. Females are typically larger with more muted, tan or gray coloration (in species like P. regius), whereas males are smaller, sleeker, and feature high-contrast black-and-white patterns with metallic green or blue chelicerae.
How long do jumping spiders live in captivity?
Most captive jumping spider species have a modest lifespan of 1 to 2 years, with females generally living slightly longer than males, especially if the females do not produce unfertilized egg sacs.
