The Bark Scorpion is probably the single most feared bug in Arizona. They are the most venomous scorpion in the U.S. and stings thousands of people each year. Although death is extremely rare (only two people within the last 40 years), the sting is extremely painful and can linger for several days. They are light in color, three inches in length, and considerably smaller than their relative the desert Hairy Scorpion. With an exoskeleton that prevents the loss of moisture and the ability to go a year without food or water, this arachnid is well-suited for the desert environment.

The Bark Scorpion can live in attics if it receives an even sporadic supply of crickets, cockroaches, and other bugs. The Bark Scorpion is one of the only scorpions known to congregate in large numbers. This can lead to, in some instances, a homeowner seeing dozens of them in a matter of months. There is no overnight solution to control this pest. Due to its resilient nature, extreme temperature has no effect on them and store bought pesticides do not even slow them down. Professional pest control is a necessary step in eliminating its food source. Some other measures that can be taken are black-lighting and properly sealing and dusting your home. It’s only through a consistent use of pest management that the Bark Scorpion be controlled.
