Jumping Spider Enclosure Setup: Small, Simple, and All About Humidity

Jumping Spider Enclosure Setup: Small, Simple, and All About Humidity

Jumping spider setups are small, inexpensive, and genuinely simple once you understand the one factor that matters most: keeping humidity consistent. For what all of it costs, see our cost guide.

Enclosure Size

A minimum of about 4 by 4 by 7 inches, vertically oriented, works for an adult, and something closer to 8 to 10 inches tall gives more genuine climbing room. This is an arboreal species, up and down space matters more than floor area. Use a front-opening design with cross-ventilation, and house one spider per enclosure, they're cannibalistic toward each other.

A tall, vertical enclosure like the Exo Terra Nano fits these proportions well.

Temperature

72 to 82F suits this species well, and normal room temperature is usually fine without any supplemental heat at all. If your space runs consistently below about 70F, a thermostat-controlled heat mat on the side wall works, but never place heat under the substrate, and never run one without a thermostat.

Humidity: The Factor That Matters Most

Target 50 to 60% for Phidippus species like the regal jumping spider, tropical genera need more. Mist one corner of the enclosure every 2 to 3 days with dechlorinated water, using a fine mist spray bottle, and aim to leave drinkable droplets rather than soaking everything. Track it with a digital hygrometer rather than guessing. Good ventilation matters here too, humidity without airflow invites mold.

Substrate

Coconut fiber, or a coconut fiber and sphagnum moss blend, about an inch or two deep, helps buffer humidity swings between mistings. Avoid sand or vermiculite, and skip using bare paper towel as a long-term substrate, it doesn't hold moisture well enough.

Lighting

This species is diurnal and genuinely relies on vision to hunt, so provide bright ambient light on a normal 12-hour day and night cycle. UVB is not required for this species.

The Non-Obvious Requirement: Leave Room Near the Top

Jumping spiders build their silk retreat near the top of the enclosure, so it's worth positioning your access opening lower or to the side. One more useful habit: check your spider's abdomen regularly, its condition, plump versus shrunken, is genuinely the best quick daily indicator of overall health, our health issues guide covers what a shrunken abdomen and other warning signs actually mean.

This setup runs noticeably smaller and simpler than what other invertebrates on this site need, compare it against our tarantula tank setup guide, emperor scorpion tank setup guide, or Madagascar hissing cockroach tank setup guide to see how the requirements differ.

Once this setup is dialed in, see our feeding guide for what to feed and how often, our handling guide for what day to day interaction looks like, our cost guide for what all of it costs, our health issues guide for what can go wrong and why, or browse the rest of our Invertebrates care guide category.
