What Are Scorpions?

Arizona Scorpions can be found in residential and rural areas of Arizona. Scorpions are arthropods, have eight legs, two pedipalps, and a notorious tail with a venom-injecting barb. Scorpions have two venom glands that produce the venom they use when hunting and defending themselves from predators. Scorpions do not have had a skeletal structure, but instead, they have an exoskeleton made of chitin, which is similar to the shell found on shrimp. There are many types of scorpions that reside here, with the bark scorpion being the most common. Scorpions are closely related to mites, ticks, and spiders. Although scorpions are most often associated with desert climates, there are variations of the scorpion that are also found in moist climates like North Carolina, British Columbia, Brazilian forests, and even in the Himalayas. The scorpion has been around for hundreds of millions of years as is a true survivor of the lands. You can click here to learn more about Arizona scorpions.

What Do Scorpions Eat?

Scorpions can live for months without eating but need water to survive. When hunting, scorpions use their pincers to capture their prey. They can crush their prey with their pincers alone and may not need even need their barbs to sting smaller insects. When they do use their stingers, they use them to inject a neurotoxic venom into their prey that temporarily paralyzes them, allowing the scorpion to feed on them without much resistance. When feeding, scorpions are unable to ingest solids, and only consume liquids from their prey. They have a very sharp claw-like mechanism that extends from their mouth and pulls small parts of the prey apart, allowing them to feed directly on the liquids. During the Arizona summer months, scorpions become more active, often leading them indoors to hunt.

Where Do Scorpions Live?

Scorpions are commonly found hiding underneath or between rocks, wood piles, clutter, and dense foliage. The Arizona bark scorpion is often found on vertical surfaces like the siding of your home, interior walls, trees, brick fences, and in bushes. Scorpions can nest in walls, indoors, and outdoors. If your home was built on a nest, it’s possible that there is a colony of scorpions located right under your home. There are plenty of preventative measures that can be taken to keep scorpions out of your home. Some scorpions will burrow, creating a single occupant den for them to reside in. These dens can be up to a meter deep. These dens are also used to ambush wondering insects. The entry areas of these burrows are at the surface level where inquisitive insects my wonder in for a peak, or to take of residence and find an aggressive scorpion waiting for them on the inside. Adult males will abandon their burrows for long periods of time to locate a mate.

What Are The 3 Most Common Scorpions Found In Arizona?

1. The Bark Scorpion

Out of these three common scorpions, the bark scorpion is the only one of them that prefers to climb vertical surface areas and can be found on rocks, walls, and trees. Often times bark scorpions will prefer to reside on the underside of objects like garden hoses and yard tools, and people are commonly stung as they reach to pick these objects up.

Bark scorpions are attracted to moist areas and are often found stranded in bathtubs and sinks. Their attraction to moisture also makes them more likely to take up residence in your home if the opportunity presents itself. They can be seen in the evenings claiming interior walls, hanging from the ceiling, or hiding in dark places like closets and crawl spaces. Bark scorpions are one of the three most common types of scorpion found in Arizona, but can also be found in parts of California, Sonora, Utah, and New Mexico.



2. Stripe-Tailed Scorpion

The stripe-tailed scorpion is a well built medium-sized scorpion that can be found burrowed underneath rocks during the day, and venturing out of their burrows in the evening to feed. They have a sturdy tail with dark ridge patterns running the length of the scorpions tail and are typically about 2 inches in length.


3. The Giant Hairy Scorpion

Depending on how deep the moisture lines are, the giant hairy scorpion could burrow as deep as 8 feet into the ground. The giant hairy scorpion has a very large tail and barb, it’s sting is swift and effective on prey but only causes mild pain in humans.

About Scorpion Stings

Scorpion venom is a neurotoxin, it’s a chemical that affects the nervous system, ultimately killing or paralyzing their prey. Most scorpions in Arizona don’t have the potency to kill humans, although it is suggested that you contact your medical practitioner if you or someone in your family is stung by a scorpion.

Signs You Have Been Stung By A Scorpion

Arizona scorpion stings are scary, painful, and possibly traumatizing to some, but rarely are the stings of scorpions in Arizona life-threatening. Those that are threatened most by the venom are young children, the elderly, and those that may have complicated health issues.

In Arizona, the bark scorpion is the only scorpion species with venom potent enough to cause severe symptoms in the young and old alike. When scorpion stings happen in areas that don’t have easy access to medical care, death can become common among infants and the elderly. Healthy adults usually don’t need to be treated for scorpion stings. If a child is stung, the same amount of venom that an adult can withstand may have more serious results for a child. If a child is stung by a scorpion, seek medical treatment immediately.

Scorpion stings typically cause pain and throbbing in the area that was stung. Sometimes there are additional symptoms that can be quite intense, even if redness and swelling aren’t present at the location where the sting took place.
