Spider Control in Oregon and Washington
Take Back the Corners, the Eaves and the Crawlspace
Spider control starts with finding where spiders are living and what they are feeding on. A&A inspects inside and out, sweeps webs and egg sacs from the exterior, applies a residual product to the foundation, eaves, exterior lighting, window frames and entry points, and follows up with recurring service that helps cut the insects spiders eat.

How do I get rid of spiders?
Spiders go where the food is, and they get in through cracks or ride in on stored items. Washington State Department of Health notes that pesticides alone are not an effective solution for long-term spider management, so treating only the spiders you can see rarely settles it. The steps below are how an A&A technician works on the spiders, their webs and the insects feeding them:
Step 1 of 5 shown
-
Comprehensive inspection
Your technician looks for spider harborages inside and outside, checks high-activity areas such as corners, crawlspaces and outdoor lighting, and notes what may be drawing spiders in, including the insects they feed on.
-
Web removal
On the exterior, we sweep away webs, egg sacs and spider debris with an extendable brush. It clears the building and disturbs the spiders, which increases their exposure to the treatment that follows.
-
Exterior residual treatment
After the webs are cleared, we apply a residual insecticide to key areas: the foundation, eaves, exterior lighting, window frames and entry points. The aim is to reach both spiders and the insects they feed on.
-
Interior treatment as needed
If spiders are getting inside, the plan is built around what your technician finds, using chemical or non-chemical methods. Decluttering storage areas such as basements, attics and closets also takes away places for spiders to settle.
-
Ongoing prevention and monitoring
Spiders follow their food, so controlling insects around the property matters. Our recurring service helps reduce insect populations, and the Bug Bundle and Bug & Rodent Bundle both include sweeping of spider webs followed by an overhead application for spider control.
Are spiders dangerous?
Most spiders in Oregon and Washington are not a threat to people. They are useful predators that feed on pests such as flies, moths and mosquitoes. Indoors they are a nuisance, though, and a few species deserve care. Here is what is worth knowing:
-
Webs and egg sacs collect in corners, eaves and around doorways, and some spiders keep adding webbing until it piles up.
-
Black widows are the species to take seriously. They are shy and tend to bite only when threatened, and anyone who suspects a black widow bite should seek medical help.
-
Yellow sac spiders wander indoors at night. Their bites are sometimes reported as painful and may cause an allergic reaction.
-
Bites are uncommon, and Washington State Department of Health notes that many skin wounds, such as MRSA infections, get misdiagnosed as spider bites.
-
A steady supply of spiders can mean there are plenty of insects for them to eat.

Which spiders are common in Oregon and Washington?
Four kinds of spider are common around Northwest homes and businesses. How they live, how they look and what a bite means differ a great deal, so identification comes before any treatment decision.
Two other spiders come up often. Yellow sac spiders are small, pale yellow to yellow-green, and hide in white silken sacs where a wall meets the ceiling or along windowsills. Brown recluse spiders are not found in the Pacific Northwest, according to Washington State Department of Health.
-
Black widow spiders
The female is glossy black with a round abdomen, long slender legs and a red hourglass on the underside, about half an inch in body length. She builds messy webs near the ground in garages, crawl spaces and woodpiles. Oregon Department of Agriculture calls black widows likely the most harmful spiders in Oregon. Anyone bitten should seek medical attention.
-
Giant house and hobo spiders
Both came from Europe, live around homes, and look so alike that telling them apart can take a microscope. Males wander in late summer and fall, usually across floors. Oregon State Extension says the hobo spider is not dangerous despite its reputation, and WSU says the giant house spider's bite is not known to pose any threat to humans.
-
Wolf spiders
Hairy, brown to gray, and between half an inch and two inches long. They do not spin a web, roaming at night to hunt instead. They tend to come inside in fall, near doors, windows and garages, and run when disturbed. Oregon Department of Agriculture lists wolf spiders among the common Oregon spiders with no known harmful bites to people.
-
Cellar spiders
Pale, small-bodied spiders with extremely long, thin legs, hanging upside down in loose, untidy webs in corners, basements and crawl spaces. They are often confused with harvestmen, the daddy longlegs, which are not spiders. Oregon Department of Agriculture lists the cellar spider among Oregon spiders with no known harmful bites to people.
Spider prevention tips
Spiders settle where there is cover and something to eat. These five steps take both away:
-
Clear the perimeter
Move woodpiles, ladders, garbage cans, stacked building materials and leaf litter away from the building, and cut back vegetation touching it. Spiders build webs and find shelter in all of it.
-
Cut down on indoor hiding spots
Declutter basements, attics, closets and garages, and vacuum corners, ceilings and window frames regularly to remove webs.
-
Seal the ways in
Keep window screens tight, seal cracks and crevices, and fit brush-type door sweeps so spiders and the insects they eat have a harder time getting inside.
-
Check what you bring in
Look over firewood and items from sheds or garages for spiders and egg sacs, and keep shoes, clothing and toys off the floor, where spiders can get trapped in them.
-
Manage the lights
Insects gather near lights, and spiders follow. Turn off indoor lights at night, and ask your technician about yellow-spectrum lighting near doorways, which can reduce insects and spiders there.
FAQs
Why am I seeing more spiders in the fall?
Late summer through early fall is mating season for some common Northwest spiders. Males leave their shelters to look for females and are the ones most often found wandering indoors, usually on the floor. Cooler weather also sends spiders into sheds, garages and homes looking for warm shelter. Many of these spiders live in buildings year-round.
Are there brown recluse spiders in Oregon or Washington?
No. Washington State Department of Health says brown recluse spiders are not found in the Pacific Northwest, though other spiders are often mistaken for them. Oregon State Extension notes wolf spiders do not have the violin-shaped marking behind the head that brown recluses have. If you have a spider you cannot identify, send us a photo.
What should I do if I think a spider bit me?
Wash the bite with soap and water and call the poison center at 1-800-222-1222. If you can, trap the spider in a container so it can be identified. Washington State Department of Health says cold packs may help with early symptoms. If a black widow bite is suspected, seek medical help right away.
How much does spider control cost?
It depends on the size of the property and the extent of the problem, and pricing stays transparent with no hidden fees. For homes, our office team provides free estimates over the phone. We provide a complimentary site inspection for any multi-family or commercial property seeking a bid on recurring services.
How fast can a technician get here?
Next business day: contact us by noon, and we will schedule a technician to be onsite the next business day. Early treatment keeps the job smaller, so call as soon as you notice a problem.
Does A&A offer recurring pest control plans?
Yes, we offer recurring pest control programs designed to provide year-round protection against common Northwest pests. Service frequency is customized based on your property, pest pressures, and individual needs, with options ranging from monthly to quarterly visits. Recurring service helps prevent problems before they become infestations while providing ongoing peace of mind.
