Spiders in Phoenix
Phoenix Spider Species
The hot, desert temperatures of Phoenix, AZ, make it an attractive destination for many types of spiders, including some of the most feared species such as the recluse spider and the black widow spider. Desert recluse spiders are different from the more well-known brown recluse variety in that their signature violin-shaped marking is so faint as to be nearly indistinct. This can make quick identification in the field more difficult. Recluse bites first cause redness and irritation and, if left untreated, can turn into a very serious necrotic wound.
Black widow spiders in Phoenix are rarely found inside homes, but their venom contains a dangerous nerve toxin. Bites are usually nonfatal but do require medical attention. To avoid bites, pay attention when picking up items stored in sheds and garages, and be cautious of dark spaces like the ones under parked cars. Deter black widows from approaching the house by keeping outdoor lights turned off when possible, since these spiders feed upon the insects attracted to the lights. Black widow spiders are easily identified by their shiny black appearance and the distinctive red hourglass shape on the bottom of their abdomens.
