Scorpions are not equally distributed across the Austin metro. The pressure is highest west of Mopac, where the Edwards Plateau limestone provides ideal microhabitats, West Lake Hills, Rollingwood, Lakeway, Bee Cave, Barton Creek, Lost Creek, Dripping Springs, and Northwest Hills all see significantly more scorpion activity than the central or eastern neighborhoods. But scorpions occur across the metro, and the species causing residential complaints is always the same: Centruroides vittatus, the striped bark scorpion.
We reviewed every licensed pest control company operating in the Austin metro over the past six months. The companies that consistently solve scorpion problems share a specific protocol. The companies that take your money quarterly and don’t move the needle share a different one. Below is the framework, and the company we’d call.
The species you’re actually dealing with
The striped bark scorpion (Centruroides vittatus) is the most common scorpion in Texas and the only species typically encountered in residential settings across the Austin metro. Adults are 1.5-2.5 inches long, tan or pale brown with two darker longitudinal stripes. They’re nocturnal hunters, feeding on insects, spiders, and other small invertebrates. According to Texas A&M AgriLife Extension, the species occurs in every county in Texas, with abundance varying based on substrate, limestone karst supports many more than sandy soils.
Striped bark scorpions are venomous but not medically significant for most adults. The sting is painful (typically compared to a wasp sting) and produces localized swelling and numbness lasting hours to a day. The exception: small children, the elderly, and anyone with insect-venom allergies should treat scorpion stings as urgent, pediatric and elderly reactions can be significantly more serious.
Why your house
Scorpions enter Austin homes through six common access points: (1) weep holes in brick veneer, 3/8″ gaps designed for moisture drainage that provide direct access; (2) gaps where AC line sets, plumbing, and utility lines penetrate the slab or foundation; (3) garage thresholds with worn or absent weather stripping; (4) the slab-to-wall transition on some construction types; (5) gaps in foundation vents and crawl space access; (6) on legs or in folds of clothing, towels, or shoes left outdoors.
They’re not seeking to be inside your house. They’re seeking the cool dark harborage your foundation provides during the daylight hours after night hunting. The reason you have more scorpions than your neighbor sometimes comes down to small differences in foundation seal quality, landscaping pulled back from the structure, or proximity to undeveloped land.
What actually works
The over-the-counter approach is mostly theater. Scorpions have a tough cuticle that resists consumer-grade pyrethrin sprays at the concentrations sold to homeowners. Ultrasonic plug-ins don’t work. The Amazon “scorpion zapper” UV lights kill non-target moths more than scorpions. Citronella does nothing. Cedar oil sprays don’t penetrate the cuticle.
What works is a four-part protocol:
1. Exterior residual treatment with professional-grade products. A combination of a pyrethroid (typically lambda-cyhalothrin or bifenthrin) plus a non-repellent (fipronil, sometimes chlorantraniliprole) applied to the foundation perimeter, the rock landscaping immediately adjacent, and known access points (weep holes, AC line penetrations, slab transitions). This is not the same product the OTC market gets. Properly applied, residual lasts 30-60 days.
2. Interior targeting where appropriate. For homes with active intrusion, targeted interior application at garage thresholds, under sinks, behind toilets, and at wall-base areas where scorpions have been found. Not whole-house spray. Surgical placement.
3. Exclusion at access points. The high-leverage work most pest companies skip. Sealing weep holes with stainless steel mesh (not foam, scorpions chew through foam over time). Sealing utility penetrations. Adjusting or replacing garage thresholds. This is labor; it’s also the work that delivers permanent reduction rather than treatment dependency.
4. Habitat modification. Pulling rock landscaping back 18-24 inches from the foundation. Removing wood piles, leaf piles, and debris from against the house. Trimming foundation plantings to allow air circulation. Each reduces the harborage at the foundation.
Why pest companies fail at scorpion work
Most pest control companies in Austin offer “scorpion service” as a line item on the residential menu. Most don’t do the work properly. The failure pattern: a 15-minute exterior perimeter spray with a residual product (often consumer-grade strength), no inspection of the access points, no exclusion offered, no habitat advice provided. The customer pays $79/month and continues finding scorpions, because the actual sources of the problem were never addressed.
The companies that solve scorpion problems do four things differently: they walk the structure-to-soil transition on the first visit, they identify and seal access points (or quote the exclusion work as a separate service), they use professional-grade chemistry at correct concentrations, and they give you a free re-service guarantee when scorpions return between scheduled visits.
What to expect on cost
Scorpion-focused service for an Austin home runs $90-$180 per quarterly visit on a typical property, with initial treatment $200-$400. Properties west of Mopac (West Lake Hills, Lakeway, etc.) typically pay the upper end of the range. Exclusion work as a one-time add-on for typical scope runs $400-$1,200. Skip the $79/month “monthly perimeter” offers, they’re not equipped for Austin-level pressure.
What separates good from bad
The companies that solve Austin scorpion problems share three traits: (1) an ACE-certified entomologist or equivalent technical depth on staff, (2) a treatment protocol that includes exclusion as part of the work, and (3) a free re-service guarantee when scorpions return between visits. The companies that don’t are the ones selling the same quarterly perimeter to a Hill Country home that they sell to an apartment in Pflugerville.
