There are approximately 1,300 different species of scorpions worldwide, and more than 40 here in Arizona. However, it is by far the Arizona Bark Scorpion that gives homeowners the most headache. At first glance, the Bark Scorpion is smaller and less assuming that the larger scorpions seen in Hollywood adventure films. Yet, it is highly venomous, capable of delivering a sting that is potentially life-threatening.
As the name implies, the Bark Scorpion is capable of climbing trees, but they also like climbing brick, stucco, and other materials. Most scorpions cannot climb at all, but the Bark Scorpion is capable of climbing vertical surfaces and even hanging from ceilings. In addition, Bark Scorpions are capable of curling their stinger next to them, allowing them to squeeze between spaces no thicker than a credit card. These two qualities allow them easy access to homes in Phoenix and Casa Grande.
Bark Scorpions have another unique quality: under exposure to a UV light (also known as a “blacklight”), they glow a bright green color. This allows pest control specialists and homeowners to easily inspect for scorpions in the yard or house at night.
