Spiders
Have a spider problem? We can help!
Spiders, like most pests, come inside when the weather becomes cool and damp. While there are hundreds of types of spiders in Washington state, the main kind that cause concern around here are the yellow sac, hobo, and black widow spiders. All three of these have venom.
The yellow sac spider is the kind that typically makes its home in ceiling corners of rooms. They look yellow and slightly transparent. A bite from one of these can cause a skin lesion that takes a while to heal. Unless you are pressing a hobo spider to your skin they probably won’t bite, but their venom can cause skin irritation. So no hugging a hobo spider! And no, they won’t chase you.
The black widow, on the other hand, can deliver a nasty bite. Untreated, the venom can reach the person’s heart and cause some real damage. Spiders bite for hunting (you are too big a prey for them), and self-protection. Most people are bitten when they accidentally brush against one of them, or while they are trying to rid their house of the interloper – so call a professional!

How can I tell I have a spider problem?
There are many different species of spiders in this area. You won’t ever see most of them, but you will most likely see the Yellow Sac, Hobo, and Black Widow spiders. These three are the ones to watch out for as their bites are poisonous and painful. There are a couple of others that you might see – the big Crab spider, and what people call the “Jumping” spider because it moves so fast. When you have spiders you will start to notice their webs being built up in your house and outbuildings.
Spiders are attracted to the warmth and light from inside our houses shining outside. They will mostly hide in cool dark places. They prey on other insects, and those other insects are attracted to the light. The spiders will go to where the light is to get their next meal, and that means coming inside your house.
You can find spider webs in the corners of your ceiling, under cupboards, behind big pieces of rarely moved furniture. They will nest in the folds of your curtains, tucked up under the books on your shelf, and behind your TV. In your outbuildings you can find the webs in the ceiling rafters, behind your tools and behind the boxes you store things in.


What steps can I take to keep my home or business spider-free?
You can change your lightbulbs to lower the light in your house so it doesn’t project as much to the outside. Close your window shades tightly, and keep your covers off the floor in your bedroom because the spiders can easily crawl up into your sheets.
Outside your house switch from fluorescent to yellow light bulbs (“bug lights”) to tone down the amount of light.
