Jumping Spider as a Pet: Care Guide for Phidippus regius & Other Jumpers

TL;DR: Jumping spiders — especially Phidippus regius (females 12–22mm, males 9–13mm) — are increasingly popular exotic pets prized for their intelligence, curiosity, and willingness to be handled. They need vertical enclosures with good ventilation, moderate humidity (50–65%), and temperatures of 72–80°F, and are fed appropriately sized live insects 2–3 times per week. P. regius is protected in Florida — always purchase captive-bred animals from reputable vendors.

If you've spent any time on exotic pet forums or invertebrate hobbyist communities in the last few years, you already know jumping spiders are having a moment. Videos of tiny, fluffy spiders tilting their oversized heads at cameras rack up millions of views. Their massive forward-facing eyes — round, dark, and oddly expressive — give them the kind of face you'd expect on a puppy, not an arachnid. They track your movements, investigate new objects with genuine curiosity, and often walk calmly onto a keeper's hand without any drama.

At Krawlo, we primarily cover reptiles and amphibians, but our mission has always been broader than that: exotic pets of all kinds that deserve proper care information. Jumping spiders are one of the most exciting entries in that category right now — and they're wildly underrated as first-time invertebrate pets. This guide covers everything you need to set one up, feed it, handle it, and understand what you're getting into.

The Species You Can Actually Keep

Not all jumping spiders are equal as pets. Here are the four species most commonly kept in the hobby:

Phidippus regius — Regal Jumping Spider

The crown jewel of the hobby. P. regius is the largest North American jumping spider — females reach 12–22mm, males 9–13mm — and is native to the eastern United States and the Caribbean. They're strikingly marked, often with bold black-and-white patterns, and females can display dramatic color variation. Their iridescent blue-green chelicerae (the "jaw" region) are a signature feature.

P. regius is the most widely captive-bred species in the US, making it the easiest to source ethically. They're generally calm and handleable from a young age. Note: P. regius is protected in Florida — collecting wild individuals there is illegal. Purchase captive-bred animals from reputable vendors.

Phidippus audax — Bold Jumping Spider

Smaller than regius but equally personality-rich. P. audax is one of the most common jumping spiders across North America and is legal to wild-catch in most US states (always check local regulations). Their bold white spots on a black background make them instantly recognizable. Many keepers get their start with a wild-caught audax before moving to captive-bred animals.

Hyllus diardi — Asian Jumping Spider

A Southeast Asian species growing in popularity in the US hobby. Slightly larger-bodied than P. audax, Hyllus diardi females have a distinctive banded pattern and are known for being particularly tolerant of handling. Because they're imported rather than locally collected, captive-bred specimens are the only ethical sourcing option.

Portia Species — The Intelligent Hunter

Portia jumping spiders are the geniuses of the spider world — capable of solving novel hunting problems and planning multi-step strategies to catch prey. They're fascinating to observe but not recommended for beginners. They're slower, more cryptic, and significantly harder to source and maintain.

What Makes Jumping Spiders Special

Eight Eyes, Two That Matter Most

Jumping spiders have eight eyes arranged in a distinctive pattern, but the two enormous forward-facing principal eyes are what make them so striking. These eyes provide exceptional binocular vision with precise depth perception — critical for a predator that hunts by stalking and leaping. Unlike most spiders, which rely on vibration and proximity to detect prey, jumping spiders can spot and track movement from many body-lengths away.

Those big front eyes also have a narrow field of view and are moved internally by muscles (rather than the whole eye rotating), giving the impression of shifting attention. It's that constant visual engagement with the world — including with you — that makes them feel so alert and "aware" compared to other invertebrates.

Active Hunters, Not Web Builders

Jumping spiders do not build prey-catching webs. They are active hunters: they stalk, assess, and then leap — sometimes many times their own body length — to capture prey. They do build silk sacs (small, closed retreats) for sleeping, molting, and laying eggs, and you'll see silk anchor lines trailing behind them wherever they roam. But the classic orb-web is not part of their biology.

Color Displays and Courtship

Male jumping spiders perform elaborate visual courtship dances, waving their legs and displaying iridescent markings to impress females. Even in a captive setting with no female present, males will sometimes display at reflective surfaces. It's one of the most entertaining behaviors in the hobby.

Are They Safe? The Venom Reality

Yes — with an honest caveat. All spiders produce venom; jumping spiders are no exception. However, Phidippus venom is medically insignificant for the vast majority of people. A bite from a jumping spider is roughly comparable to a mild bee sting: brief sharp pain, possible localized redness or swelling, resolving within hours.

Bite risk is extremely low. Jumping spiders are not defensive biters. They very rarely bite humans even when mishandled, and most bites reported by hobbyists happen when a spider is accidentally pinched or startled. An unprovoked bite from a calm, handleable jumper like P. regius is unusual.

The exception: Anyone with spider venom allergies or known sensitivity to insect venom should exercise caution. An allergic reaction to jumping spider venom is rare but theoretically possible. If you've had anaphylactic reactions to bee or wasp stings, consult a physician before handling spiders.

Enclosure Setup

Height Matters More Than Width

Jumping spiders are arboreal — they live and hunt above ground level, preferring to be elevated. This means their enclosure should be taller than it is wide, the opposite of most reptile setups. A good rule of thumb: at least 5×5×8 inches for an adult, with height being the priority dimension.

Popular enclosure formats include:

• Deli cups with mesh lids: Cheap, functional, and easy to clean. Many experienced keepers use these long-term without issue.
• Small mesh arboreal enclosures: Acrylic or screen enclosures with front-opening doors are easier to work with and allow better ventilation. Look for enclosures marketed for dart frogs or small arboreal invertebrates — they share the same footprint logic.
• Repurposed food containers with modified ventilation: The DIY approach; effective but requires drilling or cutting mesh windows.

Ventilation Is Non-Negotiable

Jumping spiders need cross-ventilation — fresh air movement prevents mold, which can kill a spider during molting. Mesh panels on at least two sides (top and one wall, or two opposite walls) are ideal. Sealed glass enclosures without airflow are not suitable.

Inside the Enclosure

• Anchor points: Fake plants, cork bark pieces, or small sticks give the spider surfaces to build its silk sac and to rest on. A jumping spider without elevated structure will be stressed.
• Silk sac space: Leave one upper corner relatively clear so the spider can construct its sleeping sac undisturbed.
• Substrate: A thin layer of coconut fiber, peat, or paper towel on the floor works. Substrate primarily matters for humidity retention and cleanup.

Keep decor simple. These spiders don't need elaborate terrascaping — they need anchor points and a safe space to hide.

Temperature and Humidity

Temperature

Here is where jumping spiders are dramatically simpler than most reptiles: no heat lamp needed for most US-kept species. Room temperature — 72–82°F (22–28°C) — is the ideal range. P. regius and P. audax are adapted to North American climates and thrive at normal indoor temperatures.

Avoid placing the enclosure in direct sunlight (overheating risk) or near cold drafts. As long as your house is comfortable for you, it's comfortable for your jumping spider.

Humidity

Jumping spiders need moderate humidity — approximately 50–70% — but it should not be uniformly wet. The preferred method is spot misting: lightly mist one side of the enclosure (or the substrate) every 2–3 days. This creates a humidity gradient and provides drinking water (see below) without making the entire enclosure damp.

For Hyllus diardi and other Southeast Asian species, slightly higher humidity is appropriate. For P. audax, slightly drier conditions are fine.

Lighting

Provide a 12-hour light/dark cycle using a simple timer. Jumping spiders are diurnal — they're active during the day and sleep at night. Natural light from a window works well if direct sun doesn't overheat the enclosure. A full-spectrum LED terrarium light improves activity levels and enhances the spider's natural color displays. UVB lighting is beneficial (spider activity and behavior noticeably improve in some observations) but is not essential for basic husbandry.

Feeding Your Jumping Spider

Live Prey Only

Jumping spiders are visual hunters triggered by movement. They will not eat dead, freeze-dried, or powdered prey. Everything must be alive and moving. This is the primary thing to understand before committing to a jumping spider — you will need a steady supply of live feeder insects.

Prey Size Guide

A safe rule: prey should be no larger than the spider's abdomen. Offering prey that's too large stresses the spider and risks injury.

Fruit fly cultures (Drosophila hydei — the larger species) are the cornerstone feeder for juvenile jumping spiders and remain useful for smaller adult P. audax. They're cheap, easy to culture, and provide appropriate prey size for most young spiders.

For adult P. regius, blue bottle flies are a popular staple: nutritious, appropriately sized, and visually stimulating for the spider to hunt. Small crickets and Dubia roaches also work well.

The mealworm debate: Mealworms are accepted by jumping spiders and are convenient, but their high chitin content and fat-to-protein ratio makes them a poor exclusive diet. Use them occasionally as variety, not as a staple.

Feeding Frequency

• Juveniles: Every 1–2 days
• Adults: Every 2–3 days
• Pre-molt / just after molt: Do not feed — see Molting section below

Remove uneaten prey within 1–2 hours. A cricket left in the enclosure overnight can injure or kill a spider, particularly during the vulnerable post-molt period.

A Note on Fasting

Jumping spiders often refuse food before molting and can fast for 1–2 weeks without issue. A healthy, well-fed adult can go 2–3 weeks without eating. Don't panic over short refusals — check for signs of pre-molt instead.

Water

Never use a water bowl. Jumping spiders drink from water droplets, and a standing water dish is a drowning hazard for a small spider.

The correct method: lightly mist one glass wall of the enclosure every 2–3 days. The spider will drink from the droplets. This doubles as your humidity management strategy. Avoid soaking the entire enclosure — wet substrate breeds mold, and mold is fatal.

Molting: The Do-Not-Disturb Phase

Molting (ecdysis) is how spiders grow. A jumping spider will shed its exoskeleton periodically, emerging larger and fresh. This is the single most dangerous period in a spider's life.

Signs of Pre-Molt

• Spider goes into its silk sac and seals the entrance
• Refuses food for several days or longer
• Abdomen may appear darker and duller
• Reduced activity

What to Do During Molt

1. Remove all prey immediately — a cricket can kill a molting spider
2. Do not mist heavily — maintain normal light misting schedule but don't soak the enclosure
3. Do not disturb the silk sac — do not open, poke, or move it
4. Wait — the process takes anywhere from a few hours to multiple days; the spider may stay in its sac for days afterward while its new exoskeleton hardens
5. Wait 5–7 days post-molt before feeding — the new exoskeleton needs time to fully harden

Molting problems are rare in proper husbandry but almost always trace back to disturbance, dehydration, or a prey animal left in the enclosure.

Handling: Earning the Jump

One of the great pleasures of keeping jumping spiders is that many individuals genuinely tolerate — and seem to enjoy — handling. They're curious animals. A jumping spider placed on your hand will often turn to face you, tilt its head, and assess the situation before exploring.

Getting Started

• Start slowly. Place your hand flat near the spider and let it walk on at its own pace. Don't grab or cup — open hand only.
• Keep sessions short at first. Five minutes, then return the spider to its enclosure.
• Expect jumps. Jumping spiders jump — it's what they do. They may leap from your hand to your shoulder, or directly toward your face to get a closer look (their vision is acute at close range). This is curiosity, not aggression. Work over a soft surface initially.
• Don't force it. Some individual spiders remain flighty and never become fully handleable. Respect that. Captive breeding over many generations tends to produce calmer animals, but individuals vary.

The Face Approach

First-time handlers are often startled when a jumping spider turns to face them and then walks or jumps toward their eyes. This is normal behavior — the spider is using its principal eyes to investigate the large moving object (you) at close range. It's one of the most endearing behaviors in the hobby. Just hold still and let it look.

Lifespan: The Emotional Honest Truth

Jumping spiders live 1–3 years, with females generally outliving males. Males of most Phidippus species live under a year once mature. This is the hardest part of keeping jumping spiders for many people who become attached to their personalities.

Go in with clear expectations: you are likely to have your spider for 1–2 years. Some keepers find this liberating — it's a lower long-term commitment than a reptile with a 10–20 year lifespan. Others find the brevity genuinely painful. Both reactions are understandable. The depth of personality packed into a 1–3 year lifespan is remarkable.

Where to Buy a Jumping Spider

Captive-Bred vs. Wild-Caught

Captive-bred (CBB) jumping spiders are the preferred option. They're parasite-free, accustomed to enclosure conditions, and often calmer than wild-caught animals. Captive-bred P. regius and Hyllus diardi are widely available from specialty invertebrate vendors in the US.

Wild-caught P. audax is legal in most US states and is how many hobbyists get their start. They typically adapt well to captivity within a few weeks. Always check your local regulations before collecting.

Never buy P. regius collected from Florida — the species is protected there and collection is illegal.

Pricing

• Spiderlings (slings): $20–$40
• Juveniles: $30–$60
• Adults: $40–$150+ (adult females command a premium)

Where to Find Reputable Vendors

• Specialty invertebrate shops online (search for USPS overnight-shipped invertebrate vendors)
• Reptile and invertebrate expos — often the best prices and you can assess the animal in person
• Invertebrate hobbyist Facebook groups and Discord servers — experienced keepers sell culls and extras at reasonable prices

Avoid large generalist pet stores for jumping spiders — they rarely carry them, and when they do, husbandry and sourcing are often poor.

Is a Jumping Spider the Right Pet for You?

Jumping spiders are a remarkable entry point into invertebrate keeping. They're affordable, low-maintenance compared to most reptiles, engaging to observe, and genuinely interactive in a way that most invertebrates simply aren't. They require no expensive heating equipment, no UV lighting at the reptile level, no complex water chemistry, and no large enclosures.

The trade-offs: live feeders are non-negotiable, their lifespan is short, and veterinary care for invertebrates is limited (there are very few vets who treat spiders). They are also genuinely fragile during molting.

If you're curious about keeping an unusual pet, want something low-cost with outsized personality, and are comfortable with live insects — a jumping spider may be the most interesting small pet you've never considered.

For those who want to graduate to larger invertebrates or reptiles after their jumping spider experience, Krawlo's care guides for leopard geckos, blue-tongued skinks, and other exotic pets are a natural next step. We cover the full spectrum of unusual animals — from spiders to snakes — because the exotic pet world is bigger and more diverse than any single species.
