There are approximately 3,400 different kinds of spiders in North America. While many of them are harmless—and even consume otherwise-pesty insects—some are venomous. The guide below will help you identify which types may be dangerous so you can schedule professional spider control.

What Kinds of Spiders May Be Living in Your Home?

1. American House Spider

Parasteatoda tepidariorum is a common house spider. These comb-footed creatures live in dark places like basements, closets, and crawl spaces. They are generally brown, tan, or greyish with patterns of different shades on their legs. On average, they are a quarter-inch long but they can grow to an inch or more across with legs outspread. However, they do not pose a threat. You just might have to clean up after their cobwebs.

2. Black Widow

In most cases, the females are dark-colored and readily identifiable by reddish markings on their abdomens—and their bites are the ones that are dangerous. Luckily, these creatures tend to live outside—but that still poses a risk to family members and pets. Therefore, seek out spider control if you spot one.

3. Brown Recluse

Brown Recluse spiders are usually between a quarter and three-quarters inches long, but they may grow larger. While typically light to medium brown, they range in color from whitish to dark brown or blackish gray. Brown Recluse’s venom has a cytotoxin that can affect the tissue at the bite site, so seek medical help right away if you are on the receiving end.
