Common House Spider

Common House spiders are found worldwide and are common throughout the United States and Canada. They dwell inside structures, house spiders are most likely to be found in upper corners, under furniture, and inside closets, basements, garages and crawl spaces. Outside, they are often found spinning webs around windows and under eaves, especially near light sources that attract prey.

Common house spiders are often yellowish-brown in color with an elongated abdomen. Female common house spiders measure 5 to 8 mm in length, while males measure only 4 mm. Common house spiders are typically brown or gray in color, with darker chevron markings along their bodies.

A common house spider’s body is divided into the cephalothorax and the abdomen. Like scorpions, mites and ticks, house spiders are wingless. They are classified as arachnids rather than insects and have eight, single-lens eyes.

Did you know?
Common house spiders rarely bite unless they feel threatened. However, they may defend themselves when crushed in shoes or clothing being put on by a human.
