Jumping Spider

A small enclosure is not just acceptable but preferred — something around 5x5x8 inches works well for one adult regal jumping spider (Phidippus regius), the most common pet species. Taller than wide is ideal since jumping spiders climb constantly. Ventilation is essential, via a mesh top or side vents, since stagnant air causes health problems. Furnish with climbing branches, cork bark, and artificial plants, which jumping spiders use both for exploring and for building silk hammock retreats where they sleep and molt. Light misting every day or two maintains humidity and gives them water droplets to drink. Room temperature of 70 to 80 degrees F is fine without any supplemental heating in most homes.

Jumping spiders eat live prey exclusively. Appropriately sized crickets, flightless fruit flies (ideal for juveniles), and small roaches work well, sized no larger than the spider's body. Offer prey 2 to 3 times a week and remove anything uneaten after a day. Unlike web-building spiders, jumping spiders are active visual hunters that stalk and pounce on prey rather than waiting passively — watching this hunting behavior is one of the most rewarding parts of keeping the species.

Jumping spiders are unusually curious and visually engaged with their surroundings for an invertebrate, often turning to track movement and appearing to observe their keeper. Climbing branches and varied décor support their naturally exploratory behavior. Some keepers offer brief, supervised free-roam time in a small, secure, escape-proof space. Handling should stay minimal — they're delicate and can jump or fall — though many individuals are calm enough to gently walk onto an open hand for a short supervised moment.

Molting is the most vulnerable period in a jumping spider's life, just as it is for tarantulas — never disturb a molting spider, and avoid offering live prey right before or after a molt. Dehydration is preventable with regular light misting and a small water source. A short natural lifespan of only 1 to 2 years is completely normal for this species and not a sign of poor care. Mite issues are uncommon but possible in an unclean enclosure, so remove uneaten prey and old webbing periodically.
