A hobo spider found in Northern Utah - RentokilThe little brown spiders you’ve been seeing around the outside of your house lately are most likely hobo spiders. Hobo spiders are an invasive species that are now common in the Pacific Northwest; they have been spotted in Idaho as early as the 1960s and in Utah starting in the 1990s. More recently, they’ve been spotted in the backyards of a lot of our customers.

Having a fear of spiders is natural, but it is important to learn about how to deal with spiders properly so that you don’t accidentally wipe out any beneficial species on your property. The spider experts at Rentokil are here to teach you how to identify hobo spiders and what their bites are like. Read on to learn!

Identifying Hobo Spiders in Northern Utah

Hobo spiders are often confused for similarly-colored spiders, like the brown recluse. There are some distinct features that you can use to identify them with, though. Here are a few:

  1. Size: Hobo spiders with their legs extended are about the size of a nickel. Brown recluses, for comparison, are about the size of a quarter.
  2. Markings: Hobo spiders have lots of intricate markings across their backs in different shades of brown. Brown recluses have no markings, just differently colored segments.
  3. Webs: The web of a hobo spider will be close to the ground and look like a funnel with a dense structure and a distinct opening.

Are Hobo Spiders a Health Risk?

Hobo spiders are able to bite, but their venom has been classified as non-toxic by the CDC. Their bites were formerly believed to induce tissue damage and necrosis, or skin death, which contributed to their being confused with brown recluses.

Hobo spiders rarely bite—like many kinds of spiders, they would much rather flee than resort to attacking. If you are bitten by one, here is what you can expect:

  • Redness and swelling at the bite
  • Moderate pain for about 12 hours
  • Leg twitches

If your symptoms extend beyond these, you might have been bitten by something else. Talk to your doctor about prolonged spider bite symptoms.
