Giant House Spider: Big and Harmless

This is one of the most common spiders found inside homes in Bothell, especially during late summer and fall. Giant house spiders can look alarming due to their large size, but they are generally harmless to people.



You’ll usually find them hanging out in dark corners, garages, basements, and crawl spaces. These spiders have long legs and are typically brown with subtle markings on their bodies. They’re actually helpful because they prey on other bugs like flies and roaches.

Black Widow: Know the Warning Signs

While not common indoors, the Western black widow can still be found around Bothell, especially in dark outdoor spaces like sheds, under decks, or in woodpiles. These spiders are shiny black with a bright red or orange hourglass mark on the underside of their abdomen.

Black widow bites are rare but potentially serious. Their venom is highly potent, posing greater risks to small children and pets. If you think you’ve spotted one on your property, it’s best to let our Bothell spider control experts handle the situation safely and effectively.

Yellow Sac Spider: Small But Aggressive

Yellow sac spiders might not look like much, but they’re known for their painful bites and unexpected hiding spots. Often pale yellow or beige, they build small silk sacs where they rest during the day. At night, they come out to hunt.

They often make their way inside homes during cooler months and can be found in corners, behind furniture, or even in laundry piles. While their bites are not life-threatening, they are unpleasant and sometimes get mistaken for more dangerous spiders.

Hobo Spider: The Funnel Web Builder

Hobo spiders are another species that frequently enter Bothell homes. These medium-sized brown spiders create funnel-shaped webs in dark, quiet places like basements, crawl spaces, and garages.



Hobo spiders are often mistaken for more dangerous species, but they are not considered medically significant. Still, their presence inside your home can be unsettling. Regular inspections around baseboards and foundation cracks can help spot them early.

Jumping Spider: Tiny Acrobatics Indoors

These small spiders are easy to identify by their compact size, chunky legs, and signature jumping behavior. Often black or dark gray with shiny markings, jumping spiders have excellent vision and are curious by nature.

You’ll usually find them along windowsills or on indoor plants. Despite their active behavior, they are completely harmless to humans and are actually helpful at keeping insect populations under control.

Wolf Spider: Ground-Level Hunter

Wolf spiders are large, fast-moving spiders that don’t spin webs to catch prey. Instead, they hunt insects on foot. These spiders are usually brown with bold stripes or patterns and noticeable large eyes.

They prefer to stay outdoors but may wander into homes during cooler months or in search of prey. While their size can be intimidating, wolf spiders are not aggressive and won’t bite unless provoked.

How to Prevent Spiders in Your Bothell Home

Even if most spiders are harmless, no one enjoys finding them inside the house. Here are a few simple ways to make your home less inviting to these eight-legged visitors:

• Seal up cracks around windows, doors, and foundations
• Keep storage areas clean and clutter-free
• Reduce outdoor lighting that attracts insects (spiders follow the food)
• Regularly vacuum corners, behind furniture, and along baseboards
• Trim back shrubs and remove debris close to your home

If you’re seeing a lot of spiders indoors or you’re concerned about a potentially dangerous species, it may be time to call in the Bamboo experts for reputable pest control services you can trust.
