Parasteatoda tepidariorum, the common house spider or American house spider, is a spider species of the genus Parasteatoda with a cosmopolitan distribution. Common house spiders are synanthropic and live in and near human dwellings. Their prey mechanism is similar to that of the other cobweb spiders: the spider follows disturbances transmitted along the web to entangle and then paralyze its prey, which usually consists of household insects and other invertebrates (often considered as pests).
