The most common scorpion in Texas is the striped bark scorpion (Centruroides vittatus), and it’s not even close. Texas is home to 18 scorpion species, but the striped bark scorpion is the only one found throughout the entire state. If you’ve spotted a scorpion in your house or yard anywhere in Texas, this is almost certainly what you’re looking at.
Why the Striped Bark Scorpion Dominates Texas
The striped bark scorpion’s range is remarkable. It’s the only scorpion species in all of eastern Texas. Move west and the diversity increases: two species live near Austin, four near Amarillo, five near Fort Stockton, and a full 14 in Big Bend National Park. But at every one of those locations, the striped bark scorpion is present too. No other Texas scorpion comes close to that geographic spread.
How to Identify One
Adults average about 2⅜ inches long and rarely exceed 3 inches. The body color ranges from yellowish to tan, with two broad dark stripes running down the upper surface of the abdomen. There’s also a dark triangular mark on the front of the head, right over the eyes. The pincers and tail are slender, and males have noticeably longer tails than females. Younger scorpions tend to be lighter overall, but the last body segment and the base of the pincers are dark brown to black, which can help you distinguish juveniles from other small species.
Where They Hide and When They’re Active
Striped bark scorpions are nocturnal. During the day they tuck themselves under rocks, logs, bark, and debris. Around homes, they favor spots like firewood stacks, decorative rock beds, mulch, retaining walls, and the gaps along foundations and garage doors. They’re most active in warmer months, and heat or drought can push them indoors as they search for moisture and shelter. You’re most likely to encounter one at night, on a wall, in a sink, or inside a shoe left on the floor.
One useful trick: scorpions fluoresce under ultraviolet light. Their outer body surface glows a bright blue-green under a simple handheld blacklight, making even well-hidden individuals easy to spot during a nighttime walkthrough of your yard or garage.
What a Sting Feels Like
The striped bark scorpion belongs to the bark scorpion group, the only scorpions in the U.S. with venom potent enough to cause symptoms beyond the sting site. The venom contains neurotoxins that affect the nervous system. That said, most stings produce only local reactions: sharp, sometimes intense pain, numbness and tingling around the sting, slight swelling, and warmth. These symptoms typically resolve on their own.
Serious whole-body reactions are uncommon but possible, especially in young children and older adults. Signs of a severe reaction include difficulty breathing, muscle twitching or jerking, drooling, sweating, slurred speech, nausea, vomiting, rapid heart rate, and restlessness. In children, inconsolable crying can be a warning sign. Deaths from scorpion stings in the U.S. are very rare, but heart or lung failure can occur hours after a sting if severe symptoms go untreated.
Allergic reactions are another concern. Even if a previous sting caused only mild symptoms, a future sting can trigger anaphylaxis, a life-threatening allergic response involving hives, difficulty breathing, and vomiting.
What to Do After a Sting
For a typical sting, clean the area with mild soap and water and apply a cool compress. If you were stung on an arm or leg, rest the limb in a comfortable position. An over-the-counter pain reliever like ibuprofen can help with discomfort. Avoid sedatives or anti-anxiety medications, as they can mask worsening neurological symptoms.
If a child is stung, contact your local poison control center at 800-222-1222. If you’re having trouble swallowing, take small sips of water only and seek medical attention if it doesn’t improve within an hour. For any severe symptoms, get emergency care immediately. Hospitals can administer antivenom in serious cases. It’s also worth checking that tetanus vaccinations are current for anyone who’s been stung.
Keeping Scorpions Out of Your Home
Scorpion-proofing a home is largely about eliminating hiding spots and sealing entry points. Trim vegetation so it doesn’t touch exterior walls. Move firewood piles away from the foundation. Clear outdoor clutter like stacked pots, tarps, and unused landscape materials. Inspect the exterior for gaps around pipes, vents, door sweeps, and window frames, and seal anything larger than the width of a credit card.
Inside, shake out shoes and gloves before putting them on, especially if they’ve been sitting in a garage or closet near an exterior wall. Pull beds slightly away from walls, and avoid letting bedding drape to the floor.
For a more thorough assessment, a nighttime blacklight inspection around your foundation, patio, retaining walls, and landscaping can reveal how many scorpions are actually active on your property. These inspections are most effective after dark, when scorpions emerge to hunt, and they can help you identify the specific spots where scorpions are entering or congregating.
Other Scorpions You Might See in Texas
If you live in central or western Texas, the scorpion you found may not be a striped bark scorpion. The species diversity increases dramatically as you move west. The Big Bend region alone hosts 14 of the state’s 18 species, and areas around Fort Davis, Langtry, and Fort Stockton support between five and eight species each. These include larger, heavier-bodied scorpions with thicker pincers that look quite different from the slender striped bark scorpion. If the scorpion you found is bulky, dark-colored, or lacks the distinctive twin dorsal stripes, you may be dealing with one of these less common western species. In eastern and central Texas, though, identification is straightforward: if you see a scorpion, it’s almost certainly a striped bark scorpion.
