Arizona Brown Spiders

The Arizona brown spider is a relative of the true brown recluse spider. It can be anywhere from the size of a nickel to a quarter, with a darker brown fiddle shape on its head. It lives in undisturbed areas of houses, garages and storage buildings, as well as in the desert.

Signs and Symptoms of a Bite

The bite of this spider is potentially dangerous to humans. The most common reaction is a spreading sore at the site of the bite, which if untreated, may result in permanent tissue damage or necrosis.

Treatment

Wash the area with soap and water. Call the poison center immediately at 800-222-1222 to determine whether the bite can be cared for at home or if it requires treatment by a physician and/or hospitalization.
