A frequent question we receive at Bill’s Home Service is whether the famed brown recluse spider is a common occurrence in the Vail, Arizona, area. Brown recluse spiders are notorious for their fiddle-shaped markings and their vicious bites that can cause tissue death. They are not native to southern Arizona; rather, they establish themselves in the U.S. Midwest region. Alternatively, the Arizona brown spider, the brown recluse’s closely related cousin, is commonly found throughout southern U.S.
Habitat
Although rare, it is not impossible to find a brown recluse spider in Vail, as they can sneak in boxes or furniture brought from the Midwest; one is far more likely to come across an Arizona brown spider. Both spiders belong to the Loxosceles family, which is a family of recluse spiders. As their name suggests, they prefer secluded areas that aren’t likely to be disturbed. Arizona brown spiders can be found outdoors in rocks and woodpiles or indoors in storage boxes and attics.
Identification
The Arizona brown spider is slightly smaller than the brown recluse, at just 1/3 inch from head to abdomen. The Arizona brown spider has a similar, darker brown, fiddle marking on its head, but it’s less distinct than the brown recluse. Both spiders have six eyes arranged in pairs, with one pair on the front and one pair on each side of its head.
Dangers
Although the Arizona brown spider is considered a medically significant pest and can cause similar tissue damage as a brown recluse, it’s estimated that less than 10% of Arizona brown spider bites result in a significant reaction. Nonetheless, if you think you may have been bitten by an Arizona brown spider, the bite should be monitored closely; seek a professional for medical evaluation.
