Texas is home to about 20 species of scorpions, but one dominates the landscape: the striped bark scorpion. It’s the most common and widespread scorpion in the state, found everywhere from the Hill Country and West Texas to suburban backyards in Dallas, Austin, and San Antonio. The good news is that scorpion stings in Texas are painful but rarely dangerous for healthy adults.
The Striped Bark Scorpion
The striped bark scorpion (Centruroides vittatus) is the species you’re most likely to encounter. Adults average about 2⅜ inches long, with a yellowish to tan body marked by two broad, dark stripes running along the upper surface of the abdomen. A dark triangular mark sits on the head between the eyes. The pincers (pedipalps) are slender, and the tail is long and thin, with males having noticeably longer tails than females. Younger scorpions tend to be lighter in color, with a dark brown to black tip on the last body segment.
Populations in the Big Bend region of far West Texas can look quite different. Some are only faintly striped or completely pale, which can make identification tricky if you’re used to the classic two-striped pattern.
Texas also has several less common species, including the Texas cave scorpion (a darker species found in limestone caves and rocky areas of Central Texas) and the straight-faced solifugid, which people sometimes mistake for a scorpion. But the striped bark scorpion accounts for the vast majority of encounters and stings statewide.
How Dangerous Are Texas Scorpion Stings?
A sting from a Texas striped bark scorpion hurts, sometimes intensely, but it’s not in the same league as the Arizona bark scorpion, which is the only scorpion in the U.S. considered truly medically significant. Healthy adults stung by a Texas striped bark scorpion typically experience localized pain and burning without significant swelling or redness. Numbness and tingling around the sting site are common and can sometimes spread to other parts of the body.
Most adults don’t need medical treatment. The pain usually peaks within the first hour or two and fades over the next several hours, though tingling and numbness can linger for a day or longer.
Higher Risk for Children and Older Adults
Young children and older adults face the greatest risk of serious reactions. In children under 10, symptoms can go beyond local pain to include rapid, jittery eye movements, excessive drooling, muscle twitching, and difficulty swallowing. Children may rub their face or nose repeatedly as numbness and tingling spread. In rare cases, respiratory problems can develop, which is a medical emergency.
Severe allergic reactions (anaphylaxis) are also possible, even if a previous sting caused only mild symptoms. Signs of anaphylaxis include hives, trouble breathing, nausea, and vomiting. This requires immediate emergency care.
Peak Scorpion Season in Texas
Scorpion activity in Texas ramps up in late spring and peaks in June and July. This catches many homeowners off guard, especially those who saw little activity through the spring and assumed the season would stay quiet. The spike happens because scorpions are most active when nighttime temperatures stay at or above 76°F. Once summer nights consistently hit that threshold, scorpions come out in force to hunt insects.
Activity tapers in the fall as temperatures cool, but scorpions don’t disappear. They seek shelter in warmer spots, which is often how they end up inside homes. In warmer parts of South and West Texas, encounters can happen nearly year-round.
Why Scorpions Enter Your Home
Scorpions don’t come inside looking for people. They follow their prey (insects, spiders, and other small arthropods) and seek out dark, moist hiding spots. Common entry points include gaps around doors, windows, utility lines, and foundation cracks. Once inside, they gravitate toward closets, shoes, folded laundry, bathrooms, and garages. Shaking out shoes and clothing before putting them on is a habit worth building in scorpion-prone areas.
Landscaping that touches your home’s exterior walls acts like a bridge. Woodpiles, leaf litter, brush, and rock features near the foundation give scorpions both daytime hiding spots and easy access to the house.
Keeping Scorpions Out
Physical exclusion is the most effective long-term strategy. Start by inspecting and sealing gaps around doors, windows, utility penetrations, and the foundation. Weatherstripping under exterior doors is one of the highest-value fixes, since even a small gap is enough for a scorpion to squeeze through.
Outside, keep vegetation trimmed back from exterior walls. Remove leaf piles, brush, and debris that accumulate near the house. Store firewood well away from the structure and off the ground. These steps reduce the insect populations that attract scorpions in the first place and eliminate the sheltered pathways they use to reach your walls.
Professional pest control can help in high-pressure areas. Targeted perimeter treatments around the foundation, entry points, and known hiding spots reduce scorpion numbers, though no chemical treatment eliminates them entirely. The most effective programs combine exterior treatments with sealing recommendations and seasonal follow-up visits, since scorpion behavior shifts between summer and fall.
What to Do After a Sting
For adults with only local symptoms (pain, numbness, tingling at the sting site), home care is usually enough. Wash the area with mild soap and water. Apply a cool compress to help with pain and swelling. Over-the-counter pain relievers can take the edge off while you wait for symptoms to subside.
If a child is stung, contact your local poison control center right away at 800-222-1222. They can assess the situation over the phone and tell you whether the child needs to be seen. Watch for signs of a body-wide reaction: muscle twitching, unusual head or eye movements, drooling, difficulty breathing, or slurred speech. These symptoms, in a child or an adult, warrant emergency medical care. Hospital treatment for severe stings can include intravenous pain management and, in serious cases, scorpion antivenom.
