Bark scorpions are a common pest across the Southwest. The warm, dry biome of the desert is an oasis for scorpions of all kinds. These tiny creatures can be mostly found crawling around all parts of the Grand Canyon state. They may seem harmless, but bark scorpions are anything but. 

At Burn’s Pest Elimination, we understand the importance of keeping these pests out of your home. We have years of experience with scorpions and want to help you keep your home scorpion free. Whether you are a traveler passing through or a long-term resident, here’s what you need to know about bark scorpions. 

Where do Bark Scorpions Live?

From the Grand Canyon to the Sedona Desert and beyond, bark scorpions can be found scuttering around. They can climb up trees, rocks, and walls, where they can be found in cracks and crevices. Be careful lifting rocks or shifting yard waste, you might just encounter one.

During the winter months, the scorpions will hibernate. As the weather warms up, they start becoming active again. They are commonly found in groups of 30 or more. So if you spot one, there are likely dozens more nearby. 

What do Bark Scorpions Eat?

These tiny creatures eat mostly small insects. Centipedes, spiders, crickets, and other scorpions can all fall prey to these predators. Bark scorpions can run up to 12 miles per hour, making it easy for them to target and sting their prey. These nocturnal hunters, spend their days hiding under rocks, or piles of leaves and bark. As the sun starts setting, they start watching for prey to cross their path. 

Alternatively, several other animals will feed on bark scorpions. Birds, such as owls and bats like to snack on these scorpions. Tarantulas and lizards commonly feed on bark scorpions too.

How to Identify Bark Scorpions

Like other scorpions, they have eight legs, pinchers, and a segmented tail ending in a barbed stinger. But unlike other scorpion species, the bark scorpion is highly venomous. There are 2,000 scorpion species worldwide, but only 30 species are venomous. In the United States, bark scorpions are the most venomous. 

Bark scorpions are very small and are typically between ½ an inch to 1 inch long. Male bark scorpions have been known to grow to 2 inches in length. They vary in color from light tan to dark brown but glow in the dark under UV light. If they have recently molted their exoskeleton, they won’t glow. 

How to Prevent Bark Scorpions from Invading Your Home

Bark scorpions love cool, dark spaces. In the home, they will often be found in basements, crawl spaces, under sinks, and cabinets. If you spot a scorpion in your home, lay sticky traps down to catch it. Don’t try to pick it up. 

Outside, scorpions can be found under leaf litter and stacks of wood. They also like to hide in small cracks and crevices around the foundation of your home. For preventative measures, clean up yard waste debris, stack wood away from your home, and caulk any cracks. The more uninviting your yard seems the more likely scorpions will move on.
