Habits

The house spider randomly selects its web locations and creates a tangled web. If a web does not yield prey it is abandoned, another site is selected, and a new web is built.

Habitat

House spiders have a difficult time surviving in modern homes due to low humidity and fewer insects for food. They are more likely to prosper inside structures like garages, sheds, barns and warehouses. Outside, these domestic spiders are often around windows and under eaves, especially near light sources that attract prey.

Threats

Common house spiders are nuisance pests, but they pose no threats to humans.
