Even though the common house spider is pretty much harmless, it’s commonly found in homes all over the country. This nuisance pest might not put you and your family in danger, but that doesn’t mean it’s okay to have dozens of these guys crawling around your home. Here’s some basic information about the most common spider found throughout the U.S.



  • Size:
    • Male: 1/8 inch – 3/16 inch
    • Female: 3/16 inch – 5/16 inch
  • Color: Yellowish Brown
  • Distinguishing Characteristics: Elongated abdomen; several dark stripes meeting at an angle on the abdomen
  • Whereabouts: Throughout the U.S.; areas with high humidity and other insects present

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.

Having a home filled with spiders isn’t exactly a dream scenario, so it’s up to you to keep these creepy crawlers out of your house. When your home becomes infested with spiders or any other pest, contact Knockout Pest Control. To learn more or to schedule an inspection, give us a call a (800) 244-7378.
