Why Twin Cities Basements Attract Spiders—And How to Keep Them Out

In Minnesota, it’s common to spot a spider or two in your basement—especially as the seasons change. While most are harmless, nobody wants their home turning into a spider sanctuary. If it feels like your basement is a magnet for webs and creepy crawlers, you're not imagining things.

Here’s why basements in the Twin Cities attract spiders—and what you can do to keep them out.

Why Spiders Love Basements

1. Dark and Undisturbed

Spiders prefer areas where they won’t be disturbed, and basements offer just that—especially in storage corners, utility rooms, or crawl spaces.

2. Other Insects Are There

Spiders go where the food is. If your basement has ants, silverfish, flies, or other bugs, spiders will follow.

3. Moisture

Minnesota basements can get humid—especially older homes with sump pumps or poor ventilation. Some spider species, like cellar spiders, thrive in damp environments.

4. Easy Access

Unsealed windows, cracks in the foundation, and gaps around pipes are all common spider entry points.

How to Keep Spiders Out of Your Basement

1. Reduce Clutter

The more storage bins, piles of laundry, or cardboard boxes you have, the more places spiders have to hide.

2. Dehumidify

Use a dehumidifier to keep moisture down. This helps discourage both spiders and the bugs they eat.

3. Seal Entry Points

Caulk cracks, install weatherstripping, and inspect window frames—especially if your basement has egress windows.

4. Vacuum Regularly

Webs, egg sacs, and the spiders themselves can all be removed with routine cleaning.

5. Control Other Pests

Spiders feed on other bugs. Eliminating their food source is one of the best ways to reduce their presence.
