What You Need to Know About Scorpions in Tucson
Scorpions at a Glance
Scorpions are arachnids, relatives of spiders, ticks, and mites. They are famously known for their curved tails tipped with a venomous stinger. While their appearance can be intimidating, most scorpions are harmless to humans. Of the 90+ scorpion species found in the United States, more than 40 reside in Arizona, making Tucson a prime spot for scorpion encounters.
These nocturnal creatures come to life after sunset, often searching for food (insects and other small prey). During the day, they find refuge in shaded areas such as rock crevices, under debris, or occasionally inside homes.
Why Tucson?
Scorpions thrive in warm, dry climates. Tucson’s desert environment, with its abundance of hiding spots and steady temperatures, creates the perfect conditions for scorpions to flourish. Our local scorpion population plays a vital role in controlling pest populations, making them key figures in the desert’s ecosystem.
Common Scorpion Species in Tucson
1. Bark Scorpions (Centruroides Sculpturatus)
- Description: The bark scorpion is perhaps the most feared scorpion in Arizona. These small, pale yellow creatures grow to about 2-3 inches long and are easy to identify by their thin pincers and tail.
- Behavior: Bark scorpions are climbers, often found in trees, walls, or the cracks of buildings. Unlike other species, they are social and may cluster together.
- Danger Level: These scorpions are venomous, and their stings can cause intense pain, numbness, and symptoms like difficulty breathing in sensitive individuals. While the sting is rarely life-threatening, children, the elderly, and those with allergies should exercise caution. Medical attention is recommended for severe reactions.
2. Striped Tail Scorpions (Paravaejovis Spinigerus)
- Description: Also known as the devil scorpion, this medium-sized scorpion is light brown with distinct dark stripes on its tail.
- Behavior: Striped tail scorpions are ground dwellers and prefer to hide under rocks or logs. They are less likely to venture indoors than bark scorpions.
- Danger Level: Their venom is mild. Stings can be painful but not dangerous to humans, similar to a bee sting.
3. Desert Hairy Scorpions (Hadrurus Arizonensis)
- Description: The desert hairy scorpion is the largest scorpion species in the U.S., reaching lengths of up to 6 inches. True to its name, it has hairs across its body, which are sensory tools. It is yellow with a dark back and is quite striking in appearance.
- Behavior: They enjoy burrowing and are commonly found in desert sands. With their large size, these scorpions can seem intimidating, but they are predominantly shy creatures.
- Danger Level: Desert hairy scorpions are not considered dangerous to humans. Their venom is relatively weak, with stings causing mild irritation.
4. Yellow Ground Scorpions (Vaejovis Confusus)
- Description: These small, yellowish-tan scorpions are very similar in coloration to the bark scorpion but lack the slender hands and tail segments of their more venomous relatives.
- Behavior: Yellow ground scorpions prefer burrowing into the soil or hiding under objects. They are elusive and solitary.
- Danger Level: Their sting is typically not harmful and is comparable to a mild wasp sting.
How to Coexist Safely with Scorpions
Scorpions are generally not aggressive and will only sting when they feel threatened or cornered. While their presence can feel unsettling, following a few precautionary measures can greatly reduce the likelihood of an unpleasant encounter.
1. Seal Up Your Home
Scorpions can squeeze through tiny openings. To prevent them from entering your home, seal all cracks, gaps under doors, and spaces around pipes. Using weather stripping and mesh screens can also help keep them outside.
2. Declutter Your Yard
Scorpions love hiding in dark, cool spots. Remove piles of rocks, wood, and debris from around your property. Trim bushes and keep vegetation well-maintained to reduce potential hiding areas.
3. Use UV Flashlights
Scorpions glow under ultraviolet light, making them easier to spot at night. Using a UV flashlight is an effective way to check around your home and yard if you suspect scorpions are nearby.
4. Exercise Caution Outdoors
When hiking or camping, be mindful of where you place your hands and feet. Check shoes, clothing, and bedding for hidden scorpions before use.
5. Consider Professional Pest Control
If scorpions are becoming a frequent issue, hiring a pest control expert specializing in scorpion control can help safely reduce their population around your home.
