Jumping Spiders

Jumping Spider Control: Protect Your Home or Business


  • Jumping spiders are ambush predators that pounce on their prey.
  • Males perform a mating dance to attract partners.
  • These pests are most active in the daytime and warmer months.


Jumping spiders vary in size, but most are less than an inch long. The pests are usually black or brown with fuzzy bodies and gray, white, or orange markings. Some have iridescent scales that shift colors due to the lighting or a change in your point of view. Like most arachnids, they have eight eyes, but the jumping spider’s large, forward-facing pair allows it to detect movement at a distance.

How Do Jumping Spiders Get Inside Buildings?

Tiny jumping spiders often enter homes and businesses undetected. These arachnids hunt during the day, and they look for prey in gardens and potted plants as well as on trellises or deck railings. You may also find them traveling across home exteriors, where they crawl indoors through foundation crevices or torn window screens.

Jumping spiders take shelter in tree trunks, logs, and piles of rocks in forests across the Mid-Atlantic region. When they hide inside timber, the pests can end up in home improvement stores within piles of lumber or get inside homes when customers purchase bundles of firewood.

Signs of Jumping Spider Infestation

  • The easiest way to tell if you have an infestation is by sight. The pests often lurk around windowsills, doorways, and interior walls to hunt for insects attracted by sunlight or lamps.
  • If you suddenly notice a large number of jumping spiders in your home or business, they may have moved in to take advantage of a fly, ant, or other insect infestation in the building.
  • Jumping spiders use their silk as safety lines when they leap, but they don’t create webs to catch prey. However, they do make tent-like retreats as protection from rain or cold weather. They’ll also use shelters to molt and hide their egg cases. Spotting these webbed hideouts could indicate an issue.
  • After hatching from their eggs, the arachnids go through a series of molts. Be on the lookout for cast-off skins from jumping spiders, which may indicate that multiple pests are present.

Problems Caused by Jumping Spiders

Jumping spiders may attack when they feel threatened. Though their bites are not dangerous to humans, they can cause sharp pain as well as itching, swelling, and redness. The symptoms usually do not last long.

Prevention Tips

The simplest way to prevent a jumping spider infestation is to repair cracks in foundations, seal gaps around doors and utility wires, and replace torn screens. Keeping residential and commercial spaces clean is also important, as these arachnids eat insects that forage on crumbs in kitchens or dining areas.
