Jumping Spider
Invertebrates
The tiny, curious-eyed hunter that watches you back and needs barely any space at all!
🤓 Did you know? Jumping spiders have some of the best vision of any arthropod, with four pairs of eyes giving them nearly 360-degree awareness and sharp enough focus to visually track and judge the distance of prey before pouncing - hence the name. Many keepers report their jumping spider appearing to watch and turn to follow movement outside the enclosure, genuinely interactive behavior that's unusual for an invertebrate.
🏠 Housing & Setup
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.
🥗 Diet & Feeding
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.
🎮 Enrichment & Handling
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.
💊 Health & Common Issues
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.

❓ Frequently Asked Questions
Are jumping spiders dangerous?
No. Jumping spiders have very mild venom meant for tiny insect prey, are extremely reluctant to bite, and are essentially harmless to humans. A bite, in the rare event one happens, is typically compared to a mosquito bite at most.
How long do jumping spiders live?
1 to 2 years is typical for most pet species, sometimes slightly longer for well-cared-for females. This short natural lifespan is completely normal for the species and isn't a sign that something went wrong.
Can you handle a jumping spider?
Gently and briefly. They aren't a cuddly pet and can jump or fall unexpectedly, but many individuals are calm enough to walk onto an open hand for a short, supervised moment. Regular or prolonged handling isn't recommended.
What do jumping spiders eat?
Live prey only - appropriately sized crickets, flightless fruit flies, and small roaches, offered 2 to 3 times a week and sized no larger than the spider's body.
Do jumping spiders need a big enclosure?
No - quite the opposite. Jumping spiders generally do better in smaller enclosures, where locating prey is easier and the space feels less overwhelming. Height matters more than footprint, since they spend most of their time climbing.
