Spiders in Arizona: what the public record shows

Before you compare quotes, it helps to know which spiders actually live in Arizona, when they are busiest, and what the state figures look like. Everything below links to the agency or university page it came from.

In Arizona, the two most common venomous spiders are the Western Black Widow (Latrodectus hesperus) and Arizona Recluse (Loxosceles arizonica)

Arizona's recluse is a native desert species, not the brown recluse of the Midwest and South.

Scientists consider spiders to be beneficial because of their role as predators of insects and other arthropod 'pests'

Spiders are predators, not pests

UA Extension's closing advice is to 'respect, tolerate, and enjoy spiders.'

The more insects there are inside a building, the more likely it is to have spiders living there

Why spiders are in the house

Control the prey insects and the spiders leave on their own.

When spiders are busiest in Arizona

'In the warming temperatures of spring, more insects begin to emerge. Spiders will follow these emerging food sources' (UA Extension); large male wolf spiders and tarantulas wander indoors while searching for females.

University of Arizona Cooperative Extension names the western black widow and the native Arizona recluse (Loxosceles arizonica) as the state's two venomous spiders — the brown recluse (L. reclusa) of the south-central states is not among them. Prevention is weather stripping, screen repair, caulking, and controlling prey insects.
