House Spider Identification: What Does a Common House Spider Look Like?

A house spider's body is brown or gray, with darker chevron-shaped markings running along the abdomen and legs. The abdomen is round and bulbous, tapering into a teardrop shape, while the legs are long, thin, and often pale or almost see-through. For House Spider Identification, compare this feature with the other visible clues before choosing a match.

Could You Be Looking at a Brown Recluse?

A brown recluse has six eyes arranged in three distinct pairs, a smooth, uniformly tan-to-brown body, and a dark violin-shaped mark on its back — none of which show up on a true house spider. Check the eye pattern and back marking closely if you're unsure; a house spider's chevron pattern and teardrop abdomen are the giveaway differences.

Could It Be a Brown Widow or Black Widow?

A brown widow shows a range of brown shades with stripes along the abdomen and sides, plus an orange or yellowish hourglass mark on its underside — a mark you'll never see on a true house spider. Its body stays under about an inch long, and while it's generally more timid than a black widow and injects less venom, it will still bite if you handle it or disturb its eggs.

Is a House Spider Bite Dangerous?

Common house spiders pose little to no danger to people. They're considered a nuisance rather than a threat, and bites are rare — when they happen, they're typically dry and no more painful than a bee sting. If venom is delivered, you might notice localized swelling or itching, but medical attention generally isn't needed. Their venom is a neurotoxin similar to a black widow's, just far weaker.
