Tomball, TX & the Greater Houston Metro
Scorpion Control for Houston Homes & Businesses
Scorpions are built to outlast a casual spray. They can go months without eating, shrug off light residuals, and slip through a gap no thicker than a credit card. Our licensed pest professionals find where they are living, cut off the crickets and roaches that feed them, treat the voids and harborage they hide in, and seal the routes they use to get inside. Serving residential and commercial properties from Tomball across the Houston metro.

Houston Scorpions at a Glance
- Main species: The striped bark scorpion (Centruroides vittatus) is the scorpion found in and around Houston-area homes. It is the most widespread scorpion in Texas.
- Danger level: Stings are painful but rarely medically serious for healthy adults. Young children, older adults, and anyone with a venom allergy should be seen promptly.
- Where they hide: Under landscape rock, firewood, mulch, loose bark, and debris outdoors; in attics, wall voids, garages, and bathrooms indoors.
- Why sprays alone fail: Scorpions have a waxy outer layer, walk on the tips of their legs, and can survive months without food, so they have limited contact with treated surfaces and little reason to leave.
- What works: Inspection, prey suppression, targeted void and harborage treatment, and exclusion of entry points, followed by monitoring.
- Peak season: Late spring through early fall, with spikes after heavy rain and during summer heat.
Why Scorpions Turn Up in Houston Homes
Most people associate scorpions with the Hill Country and West Texas, and it is true that Central Texas sees far heavier pressure. But the striped bark scorpion is established across the Houston area, and certain properties see a lot of them. Wooded lots in Tomball, Magnolia, The Woodlands, and Conroe; homes backing onto greenbelts, pastures, or undeveloped land; and new subdivisions where clearing has displaced existing populations all report scorpions far more often than older, built-out neighborhoods.
Scorpions also travel with materials. Landscape limestone, decorative rock, firewood, and stacked lumber hauled in from Central Texas can carry scorpions straight into a yard that never had them. A sudden appearance after a landscaping project or a firewood delivery is one of the most common patterns we see.
Like spiders, scorpions are predators. They are not inside looking for crumbs; they are following crickets, cockroaches, silverfish, and other insects. A property with heavy cricket activity along the foundation is a property that can support scorpions. Houston’s humidity, irrigated landscaping, and mild winters keep that prey base active for most of the year.
That is why effective scorpion control has to address three things at once:
- the scorpions present now, including the ones hiding in voids you cannot see
- the insects that feed them and keep pulling new scorpions toward the structure
- the gaps and harborage that let them live next to and inside your home.
EnviRx builds treatment around that reality. We confirm what you are dealing with (a surprising number of “scorpions” turn out to be harmless lookalikes), find where the population lives, and treat the structure and the landscape together.
Signs You Have a Scorpion Problem
One scorpion that wandered in under a door after a storm is simply a wanderer. These are the signals that point to a population living on or in the structure.
Repeat Sightings in Bathrooms and Kitchens
Scorpions seek moisture, and striped bark scorpions cannot climb smooth porcelain or glass. Finding them trapped in tubs, sinks, and showers more than once is a strong sign they are moving through wall voids and/or plumbing chases.
Scorpions on Walls and Ceilings
Bark scorpions are climbers (unless its porcelain or other smooth surfaces). They scale brick, stucco, siding, and textured drywall easily, and they come down from attics and ceiling light fixtures. Sightings high on walls or overhead suggest attic activity.
Small and Large Scorpions Together
Finding juveniles alongside adults means scorpions are reproducing on site. Females carry their live-born young on their backs before the young disperse, so a cluster of small ones points to a nearby female and an established population.
Activity After Rain or Yard Work
Heavy rain floods them out of the ground and landscape, and moving rock, firewood, or debris exposes them. A spike in sightings right after either is a good indicator of how many are living close to the foundation.
Heavy Cricket and Roach Activity
Crickets piling up around the garage door and foundation, or roaches in the garage and attic, mean the food supply is in place. Where the prey base is strong, scorpions are usually nearby or on their way.
Unexplained Stings at Night
Scorpions are nocturnal. Stings while getting out of bed, stepping into shoes, or reaching for a towel are the classic scenario, and they warrant an inspection of the bedroom, bathroom, and attic above them.
Scorpions and Lookalikes in the Houston Area
Texas has close to twenty scorpion species, but around Houston, one species accounts for nearly every real scorpion call. Several other arachnids get mistaken for scorpions, and the treatment response is completely different for each. Our pest professionals identify what is actually present before recommending anything. You can read more about other pests they may be looking for in our pest library.
Striped Bark Scorpion
Painful sting · The scorpion found in Houston-area homes
Pale yellow to tan, typically two to two and three-quarter inches long, with two dark stripes running down the back and a dark triangular marking at the front of the head. Slender pincers and a long, thin tail. An agile climber that shelters under bark, rock, boards, and debris outdoors and moves readily into attics, wall voids, and garages. Females give birth to live young and can produce several dozen at a time. The sting is intensely painful at the site and can cause numbness or tingling, but it is rarely dangerous for healthy adults.
Vinegaroon (Giant Whip Scorpion)
Harmless · No stinger
Large, dark, and armored, with heavy pincers and a thin whip-like tail rather than a stinger. When threatened it sprays a vinegar-scented acid, which gives it its name. Startling to find in a garage or flower bed, but it cannot sting and is a predator of roaches and crickets.
Pseudoscorpions
Harmless · Tiny
Usually smaller than a grain of rice, with scorpion-like pincers but no tail at all. They turn up on bathroom walls, in bookshelves, and in potting soil, and they feed on tiny insects and mites. Often the first thing a homeowner calls a “baby scorpion.”
Arizona Bark Scorpion
Medically significant · Not established in Texas
The only scorpion in the United States considered potentially life-threatening, and the one behind most of the alarming stories online. Its range is the desert Southwest, mainly Arizona and nearby states. It is not found in the Houston area. If you see a pale scorpion in your home here, it is almost certainly a striped bark scorpion.
Scorpion Stings: What Houston Homeowners Should Know
Striped bark scorpion stings hurt, often for hours, and they are memorable. They are also rarely dangerous for a healthy adult. The real goals are to avoid stings in the first place and to know which situations need a call to a doctor.
Where Stings Actually Happen
Stepping barefoot across a dark floor at night. Putting on shoes, gloves, or clothing left on the floor. Reaching into a towel, a bath mat, or a pile of laundry. Rolling onto a scorpion that climbed into bedding hanging to the floor. Moving firewood, landscape rock, or boards in the yard. Pulling down attic storage. Nearly every sting starts with a hand or foot in a place the scorpion was already hiding.
Reducing Risk Before We Arrive
- Wear shoes and use a flashlight when walking through the house at night.
- Shake out shoes, gloves, towels, and clothing before using them, especially items left on the floor or stored in a garage.
- Pull beds and cribs a few inches from the wall and keep bedding, bed skirts, and blankets off the floor.
- Wear heavy gloves when moving firewood, rocks, lumber, or stored boxes.
- Do not try to pick up a scorpion by hand. Trap it under a glass jar or use long tongs.
If Someone Is Stung
EnviRx provides pest control and treatment prescriptions for your home, business and yard. EnviRx does not provide medical care for people, and nothing here replaces advice from a clinician. The general first-aid guidance published by poison control centers is straightforward:
- Wash the area with soap and water and apply a cool compress for ten minutes at a time. Keep the person calm and still.
- Do not cut the wound, apply a tourniquet, attempt to extract venom, or apply heat.
- If you can do so safely, photograph the scorpion or trap it in a sealed container for identification.
- Call the Texas Poison Center Network at 1-800-222-1222 for guidance. It is free and staffed 24 hours a day.
- Seek medical attention promptly for any sting to a young child, an older adult, or someone with a known venom allergy or heart condition. Call 911 immediately for difficulty breathing, swelling of the face, lips, or throat, hives away from the sting site, unusual eye or muscle movements, drooling, or severe restlessness.
When we find scorpion activity during an inspection, we tell you exactly where it is concentrated and which rooms and storage areas to be careful in until treatment takes hold.
Gulf Coast Scorpion Calendar
Scorpion activity in the Houston area follows temperature, rainfall, and the insect populations they hunt. Treating ahead of the warm season is far more effective than reacting in July.
| Season | What’s Happening | What We Focus On |
|---|---|---|
| January – February | Scorpions are sheltering under bark, rock, and debris and in attics and wall voids. Activity is low, but warm spells bring some out, and indoor populations stay active. | Attic and garage inspection, exclusion repairs while activity is low, harborage cleanup recommendations, landscape planning. |
| March – May | Warming nights bring scorpions out to hunt. Spring rains trigger cricket and roach surges, and mating begins. | Perimeter and harborage treatment before populations build, prey suppression, sealing entry points, monitoring setup. |
| June – August | Peak activity. Females give birth and young disperse. Heat and dry spells push scorpions toward moisture in bathrooms, kitchens, and irrigated beds; heavy rain floods them out of the ground. | Void and attic treatment, bathroom and plumbing penetration work, sustained prey control, follow-up visits. |
| September – November | Activity stays high into fall. Cooling nights send scorpions looking for protected shelter, including garages, attics, and stored items. | Garage and storage area treatment, door sweep and weatherstripping checks, attic work before winter. |
| December | Cold fronts slow activity outdoors. Scorpions already inside settle into attics and voids. | Interior harborage inspection, exclusion, and scheduling the spring preventive service. |
If you only call when you see a scorpion in the tub, you are treating in July against a population that has already reproduced. Properties on a scheduled plan get the perimeter, the prey base, and the entry points handled in spring, before the summer brood disperses.

Our Scorpion Control Process
1. Inspection and Identification
We walk the full perimeter, landscape, garage, and interior, checking landscape rock and edging, woodpiles, mulch beds, weep holes, door thresholds, plumbing and utility penetrations, attic access, and storage. We confirm whether you have striped bark scorpions or a harmless lookalike and gauge how many there are. Because scorpions glow under ultraviolet light, a nighttime blacklight inspection is often the fastest way to see the true size of a population.
2. Treatment Plan
A property with a few scorpions coming in from the yard and a home with an established attic population need different plans. We explain what we are using, where, and why, along with anything on the property that is likely to keep working against the treatment.
3. Targeted Application
We place materials where scorpions hide and travel rather than broadcasting across open surfaces: wall voids, attic spaces, plumbing chases, cracks and crevices, door thresholds, and the harborage zones around the foundation and landscape. We treat the prey insects at the same time so the food source does not keep drawing scorpions back.
4. Exclusion and Habitat Recommendations
With scorpions, exclusion carries more weight than with almost any other pest. We flag failed door sweeps and garage door seals, open weep holes, gaps around pipes and A/C lines, unscreened vents, tree limbs touching the roofline, rock and wood stacked against the foundation, and exterior lighting that draws their prey, and tell you which fixes will actually move the needle.
5. Follow-Up and Monitoring
Scorpions are long-lived and slow to respond, so a single visit is rarely the whole job. We follow up to verify activity is down, check monitoring points, and adjust if a particular area is holding out. Ongoing plans keep the perimeter and prey control maintained through the warm season.
What You Can Do Between Visits
These make a measurable difference and cost almost nothing.
- Move firewood, lumber, and stored materials well away from the house and keep them off the ground.
- Pull landscape rock, mulch, and edging stones back from the foundation and avoid stacking rock against the slab.
- Trim shrubs and tree limbs back from siding and the roofline so scorpions cannot climb onto the structure.
- Switch exterior bulbs to warm LED or amber fixtures to draw fewer of the insects scorpions hunt.
- Replace worn door sweeps, garage door seals, and weatherstripping. Scorpions can fit through a gap about 1/16 of an inch wide.
- Seal gaps around pipes, cables, and A/C lines, and keep bathroom and kitchen drains covered at night if you are seeing them in sinks.
- Fix leaks and reduce standing moisture around the foundation and in crawl spaces.
- Store items in sealed plastic totes instead of cardboard, and keep garage and closet floors clear.

Frequently Asked Questions about scorpions
Yes. The striped bark scorpion is established throughout the Houston area. It is less common here than in Central and West Texas, but properties near woods, open land, or new construction, and yards with landscape rock or firewood brought in from elsewhere, can have significant populations.
Striped bark scorpion stings are very painful but rarely medically serious for healthy adults. Young children, older adults, and anyone with a venom allergy or heart condition should get medical guidance after a sting. The Arizona bark scorpion, the only potentially life-threatening scorpion in the U.S., is not found in Texas.
Scorpions come inside following prey, moisture, and shelter. They enter through gaps under doors, open weep holes, utility penetrations, and from tree limbs onto the roof and into the attic. Hot, dry weather and heavy rain both push more of them indoors.
Scorpions have a waxy outer layer, walk on the tips of their legs, and can survive for months without eating, so they pick up very little product from a treated surface. Over-the-counter sprays also miss the attics, wall voids, and landscape harborage where they actually live. Lasting control requires targeted placement, prey reduction, and exclusion together.
Most customers see fewer scorpions within a few weeks of the first service. Established populations, especially in attics, usually take an initial treatment plus follow-up visits and exclusion work over one to three months. Because new scorpions can keep arriving from surrounding land, properties with ongoing pressure do best on a recurring plan.
We select products and placement with households in mind, favoring targeted void, crack-and-crevice, and harborage application over broadcast spraying. Your pest professional will walk through any re-entry or drying guidance for the specific materials used before leaving. If you have reptiles, fish, backyard chickens, or another sensitive situation, tell us when you schedule so we can plan around it.
Yes. Compounds in a scorpion’s outer layer fluoresce a bright blue-green under ultraviolet light. Walking the yard and garage with a UV flashlight after dark is one of the best ways to see how many scorpions are actually out wandering around on a property.
Almost certainly a pseudoscorpion. They are harmless, usually smaller than a grain of rice, and feed on tiny insects and mites. Young striped bark scorpions have a full tail and look like small versions of the adult.
Activity runs from roughly March through October, peaking in summer when young are born and heat drives scorpions toward moisture indoors. Spring is the strategic window: treating and sealing entry points in March through May gets ahead of the summer brood.
Yes. We provide scheduled monitoring and treatment programs for offices, retail, restaurants, schools, daycares, warehouses, and multi-unit properties, including service documentation for compliance and audit requirements, and scheduling that stays out of the way of your operating hours.
