Diet: Common house spiders catch prey in their web to feed on. Their diet consists of insects, including flies and mosquitoes.

Habitat: These spiders can be found throughout the year in structures although more commonly spotted in warm months. Indoors, common house spiders are found in upper corners, closets, basements, garages, and crawl spaces. Outdoors, this species will frequent areas with light sources to capture prey but can also be found under wood piles and rocks.

Threats: Common house spiders are more of a nuisance than a threat. While they can bite, it is uncommon and results in mild symptoms. Due to a similar appearance to brown recluses, it is important to contact a pest control company for accurate identification if you find any in your home.

Control: Regularly vacuum living spaces and closets, seal cracks and crevices as they are entry points, and reduce the amount of clutter around your home. You should also use screens on doors and windows and replace or repair any holes and tears.
