Jumping spiders can bite, but they rarely do, and their venom isn't dangerous to people. The fuzzy, big-eyed spiders you find on windowsills, deck railings and house walls in the Carolinas and Virginia would much rather leap away than bite. When a bite does happen, usually because someone pressed or squeezed the spider, it feels like a short sting and fades within minutes to a day or two. This guide covers what a bite feels and looks like, the common jumping spiders around homes here, whether they're safe around kids and pets, and what to do when one turns up inside.
Are jumping spiders poisonous? No. They're venomous, like almost all spiders, but their venom isn't medically significant to people or pets. Penn State Extension calls the common bold jumper a shy spider that retreats from humans and generally doesn't bite even when handled.
Do jumping spiders bite? Only when pinched, held tightly or trapped against skin. UF/IFAS describes the bite as "a sharp stinging sensation which subsides in a few minutes and requires no treatment."
What Does a Jumping Spider Bite Feel Like?
Extension entomologists describe it as minor:
- Penn State: when bold jumper bites occur, "minor pain, itching, swelling, and redness may persist for one to two days."
- UF/IFAS: a regal jumper bite is a sharp sting that fades in a few minutes and needs no treatment.
- Washington State University: symptoms are "similar to yellowjackets but less pronounced," and it's mostly the larger species that can bite people at all.
People who keep jumping spiders as pets say the same. On Reddit's r/jumpingspiders (via Google search excerpts), owners described a bite that "felt more like pressure than a stab," and one "like a light needle stick with minimal redness that was gone in less than 30 min." Another owner said theirs stung for a few days and then itched. In a thread asking keepers how many times they'd been bitten, the top answer was "Zero."
What a Bite Looks Like, and What to Do
Expect a small red bump, sometimes with two tiny puncture marks, and mild swelling or itching around it. To care for it:
- Wash it with soap and water.
- Use a cold pack for 10 to 15 minutes to ease pain and swelling.
- Don't scratch. An anti-itch cream or oral antihistamine can help with itching.
See a doctor if the redness keeps spreading after a day, the area becomes hot, painful or oozes, or you have trouble breathing, hives or facial swelling, which can mean an allergic reaction. Also keep in mind that many "spider bites" aren't spider bites at all. In a large Australian study of 750 bites where the spider was caught and identified by experts, most bites caused only minor effects, and the few significant ones were mainly from widow spiders.
Can a Jumping Spider Kill You?
No. There's no record in the extension sources we reviewed of a jumping spider causing serious harm to a person. Even the biggest local species, the regal jumper, is under an inch long. In South Carolina, North Carolina and Virginia, the spiders whose bites can need medical care are widows. See brown recluse vs. black widow and are black widows common in Charleston.
Common Jumping Spiders Around Homes
Jumping spiders are the largest spider family in the world, with 6,986 described species in the World Spider Catalog, and UC IPM counts about 300 in North America. You can recognize the family by the eyes: a row of four on the face, with two huge ones in the middle. These are the ones people in the Carolinas and Virginia ask about most:
| Species | How to recognize it | Size |
|---|---|---|
| Bold jumper (Phidippus audax) | Black and hairy with white, yellow or orange spots on the abdomen and shiny green mouthparts | Females 8 to 19 mm (under 3/4 inch) |
| Regal jumper (Phidippus regius) | Males black with white markings; females often gray, tan or orange; blue-green mouthparts | Up to 22 mm (about 7/8 inch), the largest in the East |
| Zebra jumper (Salticus scenicus) | Striped black and white; often on sunny house walls and windows | Small, well under the size of a bold jumper |
| Other Phidippus jumpers (often called red-backed) | Black and fuzzy with red or orange markings on the back | Similar to the bold jumper |
All of these are harmless to people. UC IPM says even the red-and-black Phidippus johnsoni of the West "may bite if it is disturbed, but the bites are usually not serious." For other spiders you might find, see where spiders like to hide.
Are Jumping Spiders Safe Around Kids and Pets?
Yes. A jumping spider won't chase or attack a child or pet. Bites happen when a spider is grabbed or squeezed, so teach kids to look rather than pick them up. Baby jumping spiders are even less of a concern: their fangs are tiny. Jumping spiders aren't known to harm pets that catch or eat them. Call your vet only if a pet has a lot of swelling or seems unwell after any bite or sting.
Why Is There a Jumping Spider in My House?
Jumping spiders hunt in daylight and like sunny surfaces. Penn State lists windowsills, tree trunks and deck railings, and UF says regal jumpers are often found on the walls of buildings. They wander in through open doors, gaps around windows and screens, usually following insects. Seeing one now and then isn't a sign of an infestation.
The kind thing to do is put it outside. As people on Reddit's r/Entomology point out, jumping spiders "do not do well indoors" because houses are too dry and have few insects. Slide a cup over it, slip a piece of paper underneath, and release it on a plant or porch rail.
Can You Hold a Jumping Spider?
Many people do. UF/IFAS notes regal jumpers "are easily tamed and can be induced to jump back and forth from hand to hand," and they've become popular pets. Let the spider walk onto your hand rather than picking it up, and never squeeze it. Keepers describe a "threat pose," with the front legs raised, as a sign the spider wants to be left alone. Give it space or let it walk away. Wild spiders are best left outdoors where they can feed.
How Jumping Spiders Hunt
- Eyesight: Ohio State Extension says their vision is "unparalleled by other arthropods." They see prey clearly from a distance and stalk it.
- Jumping: they don't have big leg muscles. They jump by quickly raising the blood pressure in their legs, and they trail a silk safety line in case they miss.
- No web: they don't build webs to catch food, but they spin small silk shelters to rest at night, molt and lay eggs.
- Diet: aphids, flies, moths, grasshoppers, cockroaches and other spiders. When prey is scarce, they also feed on flower nectar and pollen.
That makes them useful garden predators. If you'd like to keep spiders in general away from the house, see plants that keep spiders away.
Keeping Jumping Spiders Out
- Repair screens and seal gaps around windows, doors and where pipes and wires enter.
- Add door sweeps to exterior doors.
- Reduce insects around the house: fewer bugs at the windows means fewer hunters following them.
- Remove ones you find with a cup and paper. Spraying indoors isn't needed for jumping spiders.
If you're seeing lots of spiders of different kinds inside, there's usually an insect problem feeding them. Our spider control service covers South Carolina, North Carolina and Virginia.
¿Las arañas saltarinas son venenosas o peligrosas?
No son peligrosas para las personas ni para las mascotas. Como casi todas las arañas, tienen veneno para cazar insectos, pero casi nunca pican. Solo muerden si alguien las aprieta o las agarra con fuerza. Según la Universidad de Florida, la picadura se siente como un pinchazo que desaparece en pocos minutos y no necesita tratamiento. Si encuentras una dentro de casa, lo mejor es sacarla afuera con un vaso y un papel, porque dentro de la casa hay poca humedad y pocos insectos para comer.
Key Takeaways
- Jumping spiders aren't poisonous and their venom isn't dangerous to people or pets.
- They bite only when squeezed or held tightly, and the bite feels like a short sting.
- Wash a bite and use a cold pack; see a doctor only for spreading redness or allergy signs.
- The common ones here are the bold, regal and zebra jumpers.
- Put indoor ones outside with a cup and paper; houses are too dry for them.

Generally, yes, if you let it walk onto your hand and never squeeze it. UF/IFAS notes regal jumping spiders are easily tamed and will jump from hand to hand. Wild spiders are best released outdoors.
Pet jumping spiders can become used to being handled, and UF/IFAS describes regal jumpers as easily tamed. That's familiarity rather than affection, but it's why they've become popular pets.
Jumping spiders are often called the friendliest because they're curious, active in daylight, rarely bite and can be handled gently. Regal and bold jumping spiders are the best known.
Keepers describe a threat pose: the spider raises its front legs and faces you. It's a warning to back off. Give it space and it will usually walk or jump away.
There's no need. Jumping spiders are harmless and eat other insects. Houses are too dry for them, so the kindest option is to trap it under a cup with a piece of paper and release it outside.
