Signs of a spider problem in a Portland home
Seeing a spider now and then is normal in the Pacific Northwest. These signs mean it’s time for treatment.
Webs that return
Webs on eaves, windows and porch lights that come back within days of clearing them.
Spiders indoors in late summer
Large spiders crossing floors and walls in late summer and early fall.
Egg sacs
Silk egg sacs in corners, garages, sheds and window frames.
Lots of insects
A steady supply of flies and other insects near lights draws spiders in.
Why Portland sees so many spiders
The Oregon Department of Agriculture says most hobo spider and giant house spider sightings happen in late summer and early fall, when males leave their shelters to look for mates. Over the last 5 years, September brought Interstate Pest Management more new spider calls than any other month.
Most Portland spiders are harmless, but one on the pillow still makes you jump. Spiders follow their food, so treating the spots where they hide and the insects that draw them in works better than spraying one spider at a time.

Spiders are covered by the All Seasons Pest Service at $39/mo with a $260 one-time setup fee. If you also need rats and mice covered, the All Seasons Pest & Rodent Service is $47/mo with a $280 setup fee.
Why are there so many spiders in my house in the fall?
Over the last 5 years, new spider calls to Interstate Pest Management peaked in September. Late summer and early fall is when male house spiders leave their shelters to look for mates, so they show up on floors and walls.
Are Portland spiders dangerous?
Most spiders in Portland homes are harmless to people. The Oregon Department of Agriculture says western black widows are less common in northwestern Oregon than in southwestern and eastern Oregon, and that they occasionally turn up in Willamette Valley homes. Females are shiny black with a red hourglass under the abdomen. If you see one, keep your distance and call us.
Do you remove webs?
Yes. Our technicians sweep the webs and egg sacs they can reach on the outside of your home during exterior visits.
What if spiders come back between visits?
Call us. Re-service between scheduled visits is free on every All Seasons plan.
