Tarantula Hawks in Phoenix, AZ
Pepsis spp.
Tarantula hawks deliver one of the most painful stings on Earth. Here's what to know about this striking desert wasp.
Notes: From a Phoenix, AZ Exterminator
Appearance
Tarantula hawks are large — up to 2 inches — with a metallic blue-black body and bright rust-orange wings, making them one of the most visually striking wasps in Arizona.

Harborage
They're solitary wasps, not colony builders, and are most often seen on flowering desert plants or hunting tarantulas on the ground during warmer months to paralyze and lay eggs on.
Are They Dangerous?
Their sting is considered one of the most painful of any insect in the world, though it's rarely medically dangerous and generally not aggressive toward people unless handled directly.
Treatment
Because they're solitary and not colony-forming, ongoing general pest control that manages ground-dwelling insects and reduces attractants is the most effective approach. Talk to one of Antidote Pest's Service Pro's for full-property coverage.
Prevention Tips
Avoid provoking or handling them; they generally aren't aggressive unless directly threatened
Trim vegetation and remove flowering plants they favor away from patios and entryways
Seal gaps around foundations that lead to areas where tarantulas might burrow
Keep outdoor lighting minimal at night, since they're not strongly light-attracted but activity increases near flowering plants
Wear closed-toe shoes when walking through desert landscaping during their active season
Behavioral Notes
Tarantula hawks deliver one of the most painful stings of any insect in the world — ranked at the top of the Schmidt sting pain index — though the intense pain typically lasts only a few minutes.
Despite the terrifying sting, females use it almost exclusively to paralyze tarantulas, dragging the still-living spider into a burrow as a single food source for one wasp larva.
