They create irregular, tangled webs and are harmless to humans. In fact, they help control other insect populations within the home.

The Arizona jumping spider is a small, black arachnid with white or brightly colored markings. It has a stout body and short legs, measuring between 1/8 and 3/4 of an inch.

The Arizona black widow spider is perhaps the most well-known venomous spider in the state. The female black widow is shiny black with a distinctive red hourglass marking on the underside of its abdomen. Most black widows prefer dark, secluded areas like woodpiles, garages, and sheds.

Also known as the Arizona brown spider, the Arizona brown recluse spider is light to dark brown with a dark, violin-shaped marking on its back.

Bites can result in serious wounds due to tissue damage and should be treated promptly by a medical professional.
