Why Am I Seeing More Spiders in Snohomish County?
Understanding the Seasonal Spider Increase—and What You Can Do About It

If you've noticed more spiders around your home lately, you're not imagining it. Homeowners throughout Snohomish County often notice an increase in spider activity during late summer and early fall.
From large webs around porches and windows to spiders appearing in garages, basements, and even inside the house, this seasonal increase can be surprising. The good news is that seeing more spiders doesn't necessarily mean your home is infested. In many cases, it's simply part of the spider life cycle and the changing seasons.
Here's why you're seeing more spiders around your Snohomish County home and what you can do to reduce their presence.
Fall Is Prime Spider Season
Late summer and fall are when many common spiders have reached adulthood. As they mature, male spiders become more active as they search for females and mates. This increased movement can make spiders seem like they are suddenly appearing everywhere.
In other words, fall isn't necessarily when spiders suddenly arrive—it's when many of them are fully grown, actively reproducing, and much easier to spot.
You may notice larger spiders crossing sidewalks, patios, garages, and other areas as males move around in search of females. Females may also be highly visible in their webs, where they wait for prey and, depending on the species, encounter potential mates.
This is also why those impressive webs seem to be everywhere. Mature spiders are actively building and maintaining webs, and the cooler, damp mornings of fall can make those webs especially easy to see.
So if you're seeing more spiders around your Snohomish County home in September and October, there's a good chance you're witnessing a normal part of their seasonal life cycle
More Insects Can Mean More Spiders
Spiders follow their food.
If your property has lots of flies, moths, mosquitoes, beetles, or other insects, it can become an attractive hunting ground for spiders.
Outdoor lighting can contribute as well. Lights attract many flying insects at night, which can in turn attract spiders looking for an easy meal.
Keeping exterior lights off when they aren't needed may help reduce insect activity around doors and windows—and potentially reduce the number of spiders nearby.
How to Reduce Spiders Around Your Home
If you'd rather see fewer spiders, a few basic steps can make your property less attractive to them:
-Seal cracks and gaps around doors, windows, and the foundation.
-Repair damaged screens.
-Keep vegetation and shrubs trimmed away from the house.
-Remove clutter from garages, sheds, and other storage areas.
-Reduce unnecessary outdoor lighting at night.
-Keep outdoor areas relatively clean and free of debris.
-Address other insect problems that may be providing spiders with a food source.
-Regularly remove visible webs from exterior areas.
