While most spiders are harmless, some species of spiders in New Jersey are dangerous. If you aren’t sure which is which, you may need to call in a professional for safe spider removal.

Spider Identification: The First Step to Spider Removal

You should stay clear of spiders until a spider removal specialist can help. But, to help you out, we have listed the identifying characteristics of several common spiders in New Jersey below.

House Spider

House spiders are not a threat, but they leave annoying spent webs all over the interior of structures. Adults are: 

  • ⅛- to 5/16-inch long
  • Yellowish-brown with chevron markings on their backs
  • Whitish on their abdomens

Wolf Spider

Wolf spiders are relatively large and intimidating, but they’re harmless. In appearance, adults: 

  • Are ¼- to 1⅜-inches long
  • Have spiny long legs
  • Are dark brown with tan or yellow stripes or other markings on their stout body

Wolf spiders don’t build webs. In homes, they nest in dark, hard-to-reach places.

Black Widow Spider

This species is poisonous but not aggressive. When identifying a black widow spider, you should look for the following characteristics:

  • Shiny black with a red hourglass shape seen on the underside of a round body
  • 1½- to 1⅜-inches long

Most bites happen accidentally when a person doesn’t notice a black widow in shoes, clothing, or out-of-the-way locations.

Brown Recluse Spider

Brown recluse spiders often rest in irregularly-shaped webs. Adults are:

  • Poisonous but not aggressive 
  • Reclusive
  • Dark brown with a violin-like marking on the back
  • ¼- to ½-inch long

Brown recluse bites cause tissue to ulcerate and become vulnerable to infection. 

Dangers Associated with Spiders

Although most spiders in New Jersey are harmless, there are poisonous species that can invade homes, garages, sheds, and other outbuildings. Other spiders are also a nuisance. Spider pest control services could be your best option.

Spider Pest Control and Prevention

Here are some ways to deter spiders from infesting a home: 

  • Seal cracks and crevices in the foundation.
  • Install door sweeps under all exterior doors.
  • Caulk any gaps found around windows and doors.
  • Repair or replace damaged screens in windows and doors.
  • Reduce clutter in storage areas.
  • Close up outbuildings when not in use.

It’s smart to shake out your clothes and shoes before putting them on. If spiders are hiding in them, you need a spider pest control service.
