So, what are the most common spiders in the Pacific Northwest? The experts from Summit Pest Management are here to shed light on these creatures so you don’t have to worry .

In this blog, we’ll discuss all of the spiders you’re likely to find in Pacific Northwest homes, and what you should know about them.

What Are the Most Common Spiders in Pacific Northwest Homes?

As a leading spider exterminator in the Portland OR – Vancouver WA Metro area, we encounter a variety of spider species on our service calls. Each of these spiders presents unique challenges when it comes to removal. Whether it’s the potential health risks of black widows or the persistence of cellar spiders in damp areas, understanding their habits is key to effective pest control.

Here are the ones we encounter most frequently:

  • Black Widows: Known for their distinctive red hourglass marking, black widows can pose a serious health risk with their venomous bite.
  • Cellar Spiders: Often found in damp, dark areas like basements and crawl spaces, cellar spiders are harmless to humans and help control other pests.
  • Giant House Spiders: True to their name, these spiders are large but generally harmless, preferring dark corners and secluded areas.
  • Hobo Spiders: Often mistaken for more dangerous species, hobo spiders are not aggressive and their bites are rarely serious.
  • Jumping Spiders: These active hunters are known for their impressive agility and often startle homeowners with their sudden movements.
  • Orb Weaver Spiders: With their beautiful, intricate webs, orb weavers are beneficial garden dwellers, feeding on flying insects.
  • Sac Spiders: These spiders are known for their sac-like silk structures where they retreat during the day, and they are primarily nocturnal hunters.
  • Wolf Spiders: Large and solitary, wolf spiders are ground hunters that rarely enter homes but can be startling due to their size.

Which Common Washington and Oregon Spiders Should You Worry About?

It’s important to remember that while spiders can seem frightening, they are rarely dangerous. Most spider encounters are harmless and can even be beneficial, as spiders help control the population of other pests. The primary exception is the black widow, which can be a genuine health risk, especially to children and those with allergies.

For most people, spiders are a matter of comfort rather than safety. Seeing a few spiders around is normal and indicates that your home is part of a healthy ecosystem. However, if you’re uncomfortable with them or notice an abundance, it might be time to call in the professionals.
