Scorpions in Central Texas: A Practical Guide for Homeowners

Finding a scorpion in your home is one of those experiences that tends to make otherwise calm homeowners reach for the phone immediately. And fair enough — scorpions are alarming to encounter, they can sting, and their presence inside your home means they found a way in, which means others probably will too.

Central Texas is scorpion territory. While we are not in the highest-activity zones — that distinction belongs to the arid desert regions of west Texas and the Sonoran Desert — Central Texas homeowners, particularly those in Georgetown, Kyle, Buda, and areas closer to the Hill Country, deal with scorpion activity year-round. Here is what you need to know.

Identification: The Species in Central Texas

Texas has approximately 18 scorpion species, but Central Texas homeowners will almost exclusively encounter one: the Striped Bark Scorpion (Centruroides vittatus). It is the most common scorpion species in Texas and the most widespread in North America.

Identifying characteristics:

• Length: 2.5 to 3 inches as an adult
• Color: Yellowish-tan to light brown, with two broad, dark brown stripes running the length of the abdomen
• Long, slender pincers (chelae) relative to body size
• A dark, triangular marking on the top of the head area

Striped bark scorpions are nocturnal and are excellent climbers — unlike the stereotype, they are more likely to be found on vertical surfaces, behind pictures, in shoes, in folded clothing, or in ceiling corners than they are to be found on the ground.

A practical identification tool: scorpions fluoresce under UV (blacklight). Running a UV flashlight around baseboards, behind furniture, and along walls after dark is both effective and somewhat unsettling the first time you try it.

Are Central Texas Scorpions Dangerous?

The striped bark scorpion sting is painful — a burning, stinging sensation that typically peaks in the first few hours and resolves within 24 hours for healthy adults. For most people, it is comparable to a wasp sting: unpleasant, memorable, but not medically significant.

The exception is for individuals with venom allergies. A small percentage of people will have a systemic or anaphylactic reaction to scorpion venom, which requires immediate medical attention. Children and elderly adults are also at higher risk for more significant reactions to stings.

Important note: The Arizona bark scorpion (Centruroides sculpturatus), which is genuinely medically dangerous and responsible for most serious scorpion envenomations in the U.S., is primarily found in west Texas and the desert southwest. It is occasionally found in extreme west Texas but is not established in Central Texas. The striped bark scorpion, which you will encounter here, is significantly less venomous.

Why They Come Inside

Scorpions come inside for the same reasons most pests do: they are searching for food, water, or shelter. They eat insects — crickets, cockroaches, and other arthropods — so a home with an active general pest population is also more attractive to scorpions. Moisture is also a draw, particularly in the warm Texas summer.

New construction is a significant driver of scorpion encounters in Central Texas. When development disturbs soil in areas with established scorpion populations — which describes large swaths of Georgetown’s growth corridors and Kyle’s new subdivisions — displaced scorpions actively seek new harborage, and homes built on that land become prime targets in the first few years.

Scorpions can enter through gaps as small as 1/16 of an inch. Weep holes in brick veneer, gaps around plumbing penetrations, damaged weatherstripping, and unsealed expansion joints are all common entry points.

Prevention Tips

• Seal gaps around all exterior penetrations — pipes, conduits, weep holes (use weep hole covers)
• Replace or repair damaged weatherstripping on doors and windows
• Reduce harborage near the home: remove wood piles, debris, and excess mulch from the foundation perimeter
• Eliminate their food source: general pest control that reduces cricket and cockroach populations reduces scorpion attraction
• Shake out shoes, clothing, and towels before use, especially items stored in garages or closets
• Check bed skirts and avoid storing items under beds in scorpion-prone areas
• Use a UV flashlight to scan high-activity areas at night

When to Call a Professional

A single scorpion sighting does not necessarily mean you have a population inside your home — it may be a stray entry. But repeated sightings, or finding scorpions regularly inside, indicate either a harborage area in or around the structure, or an ongoing entry point that needs to be addressed.

Professional pest control addresses scorpions in two ways: direct treatment of harborage areas (inside and outside) and general pest control to eliminate their food source. Scorpions are harder to kill with residual products than most insects because they spend little time on treated surfaces — so the combination of targeted treatment and prey elimination is the most effective approach.

Scorpion activity tends to be higher in spring and fall, when temperatures are moderate and movement is greatest. If you are in a higher-activity zone like Georgetown or Kyle, a preemptive treatment program before spring is worth considering.
