Pest of the Month: Common House Spider


Even though the common house spider is pretty much harmless, it’s commonly found in homes all over the country.

Here’s some basic information about the most common spider found throughout the U.S.

    • Male: 1/8 inch – 3/16 inch
    • Female: 3/16 inch – 5/16 inch

What They Infest
The common house spider can be found everywhere across the United States as long as there is a high level of moisture and other insects for it to feed on. The most common areas you’ll find these eight legged pests are in garages, sheds, warehouses, and barns. However, you can also find them in high humidity areas of your home like basements, attics, and around windows.

Pest Management
If your home is currently experiencing an infestation of the common house spider, start by inspecting your home for cracks and gaps. Seal these areas with a caulking sealant while also repairing any plumbing problems attributing to small leaks and increased levels of moisture. To remove any possible eggs that these spiders might’ve laid, thoroughly vacuum your home on a regular basis.
