Common Types of Spiders in Washington

A quick Google search will reveal that there are thousands of species of spiders in existence—some are venomous while others are harmless. Here in Washington state, there are a handful of spiders to be aware of: wolf spiders, black widow spiders, hobo spiders, giant house spiders, and cellar spiders.

  • Black Widow Spiders

    Shiny black in color, black widows have a unique identifying red mark on the underside of their abdomens. This marking resembles an hourglass. The black widow spins disorderly appearing webs typically close to the ground. While they appear chaotic, black widow webs are carefully constructed to effectively capture prey. Learn more about black widow spiders.

  • Cellar Spiders

    Commonly pale yellow, light brown, or grayish in color, cellar spiders have eight long and skinny legs. They are often referred to as daddy longlegs because of the length of their legs. They spin large loose webs that have dimension (they are not flat like the webs of giant house spiders). Learn more about cellar spiders.

  • Giant House Spiders

    Giant house spiders, as their name suggests, are large arachnids that have up to a four-inch leg span. They appear in a variety of colors including dark orange, brown, and beige. These spiders have a tendency to build flat, messy webs often in corners and in areas that are not typically disturbed by humans.

  • Hobo Spiders

    Similar in appearance to giant house spiders, hobo spiders are light to dark brown in color and have a single dark stripe running down the center of their bodies. Their long, thin legs are lighter in color and do not have any banding. Hobo spiders create funnel-shaped webs.

  • Wolf Spiders

    A large species of spider, wolf spiders have stout, sturdy bodies covered in hair and eight long, spiny legs. They are black or dark brown in color and may have cream, gray, or yellow markings. These spiders do not build webs. Instead, they hide out in burrows and move quickly to hunt down and capture their prey.

Why do I have a problem with spiders?

Simply put, where there are insects, you will find spiders. They enter homes and structures through openings and are often found in corners of ceilings, in basements, attics, and other dark and/or quiet places.

Are spiders dangerous?

Of the spiders we’ve discussed, the black widow is the only one of medical significance. Black widow spider bites can negatively affect health and though not usually life-threatening, may require medical attention. If you’ve been bitten by a black widow, it is wise to consult medical experts on the next steps.

With the exception above, most spiders in Central Washington are considered nuisance pests that do not harm people or property.

How do I prevent problems with spiders?

To prevent spider infestations, you must correct the conditions around your home that attract other insects—after all, that is their food source. We recommend these helpful spider prevention tips for residents of Ellensburg and Central Washington.

  • Seal cracks and crevices found in your home’s foundation, exterior walls, and spaces found around utilities (pipes, wire, and ducts) and air conditioners.
  • Install door sweeps underneath all exterior doors, especially basement doors.
  • Caulk any gaps found around windows and doors.
  • Remove excess piles of debris from your property that could attract spiders such as woodpiles, rock piles, leaf piles, and grass piles.
