Cellar spider webs near a leaky basement window well

Why Are There So Many Spiders in My Basement?

Spiders don't just appear out of nowhere. If you have spiders, you have a secondary pest problem.

Quick Answer

Spiders are predators. If you are seeing a sudden increase of spiders in your basement, it is because they have a reliable food source indoors. Eradicating the spiders requires eliminating the underlying moisture issues and the smaller insects (like springtails or silverfish) that the spiders are eating.

The Spider Food Chain

Moisture attracts prey

Humid basements attract small, moisture-loving bugs. Spiders set up webs where these bugs congregate.

Window Wells

Leaky basement window wells are the #1 entry point for spiders hunting for warmth and food.

A client in Eden Prairie just finished their basement but couldn't use it due to cellar spiders. We identified a small leak near the egress window that was breeding springtails. We treated the springtails, de-webbed the basement, and the spiders vanished.
