In Arizona there are a dozen plus species. A few have a venomous bite, being dangerous to people. There are many areas supporting Arizona brown spiders, and the black widow inhabiting desert areas. We only on rare occasions find or hear of the Brown Recluse in the Valley.

Venomous Spiders include
The Black Widow, Arizona Brown, and the Brown Recluse

Less Venomous Spiders include
The Orb Weaver, (Garden) Cellar, (Giant Daddy Long Leg) Huntsman, (Crab) Jumping, (Landscape – Grass) Funnel Weaver, Web Dweller) and the Awesome but sometimes Feared Tarantula Spider.

The Camel and Sun spiders are in the Arachnida class and are native to Arizona, but they are not technically spiders. Just know any Spider can be intimidating especially when discovered In tight areas or when one falls on or crawls onto you as you least expect it. These instances can often cause greater injury than the spider encounter itself.

Little is more effective than a routine brushing, and removal of the web produced by the black widow spider. Liquid treatment can be applied or a material such as web a way can be effective but contacting spiders like scorpions directly with applied material is necessary to achieve a lethal dose. Unlike soft bodied insects that groom themselves arachnids don’t! 

Other Spiders in Arizona are plentiful and most come of the Garden variety. Generally speaking, they are harmless but can be intimidating. We do encounter the tarantula and wolf spider on occasion. With well-maintained landscapes and routine pest control service the concern can be remedied.
