The common house spider (Parasteatoda tepidariorum), referred to internationally as the American house spider, is a spider species of the genus Parasteatoda that is mainly indigenous to the New World. American house spiders are synanthropic and build their webs in or near human dwellings, often in secluded areas such as between loose walls and behind open doors and attic windows. American house spiders can bite humans if picked up. Although the bite of this species is relative less severe compared to other theridiids, bites of P. tepidariorum can cause severe pain with a median duration of 16 hours, and in some cases systemic effects, similar to false widows spiders.
