The Common House Spider, scientifically known as *Parasteatoda tepidariorum*, is a small spider often found in homes around the world. Typically, it has a brown or gray body with distinctive markings on its abdomen. These spiders are known for their web-building abilities, creating irregular webs in corners and undisturbed areas. Common House Spiders are harmless to humans and play a beneficial role in controlling pest populations, such as flies and mosquitoes. They are nocturnal hunters, primarily feeding on insects that get trapped in their webs. Their presence is usually a sign of a healthy indoor ecosystem.
