Parasteatoda tepidariorum
Also known as American house spiders, these spiders build their tangled webs in or near human dwellings, often in secluded areas such as between loose walls and behind open doors and attic windows. The 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). Therefore, in some regions, having those spiders inside a house may be considered beneficial. However, there is the potential hazard of a spider bite. Each egg sac contains from 100 to more than 400 eggs, with a single female producing up to 17 egg sacs. The hatchlings remain in the mother's web for several days.
