Pest Control in Kerrville, TX
Kerrville is one of the Hill Country's largest cities and draws retirees and second-home buyers who are sometimes surprised to find that the scenic cedar and oak landscape comes with a pest profile very different from the urban Texas they are used to. Scorpions, large centipedes, and mice from the surrounding woodland are more common here than cockroaches.
Kerrville pest control is Hill Country pest control, and that means the species list looks different from Houston, Dallas, or San Antonio. The semi-arid limestone environment sustains scorpions year-round, and striped bark scorpions are a standard household find in Kerr County. The Texas redheaded centipede, the largest centipede in North America, is present in the surrounding cedar-oak terrain and occasionally enters homes. Paper wasps nest under every eave. Fire ants are established along the Guadalupe River corridor and in irrigated residential areas. Mice move into homes from the surrounding woodland each fall as temperatures drop. Cockroaches are less dominant here than in the humid Texas cities, replaced by the arachnid and arthropod pressure that characterizes the Hill Country's semi-arid ecology.
The pests that matter in Kerrville
| Pest | When active | Local notes |
|---|---|---|
| Scorpions | March through November | Striped bark scorpions are common in Kerrville and throughout the Hill Country. The limestone rock outcroppings and cedar-oak terrain surrounding the city provide abundant habitat, and scorpions enter homes through foundation gaps, weep holes, and utility penetrations. |
| Fire ants | March through October | Fire ants are well established in Kerrville's residential areas and parks along the Guadalupe River corridor. Colony density is highest in irrigated areas and along the river's water-influenced zones. |
| Texas redheaded centipedes | April through September | The Texas redheaded centipede (Scolopendra heros) is the largest centipede in North America and is present in the Hill Country. It delivers a painful bite and is found under rocks, logs, and debris in and around Hill Country properties. It occasionally enters homes through gaps at the foundation. |
| Paper wasps | March through October | Paper wasps build nests under eaves, porch ceilings, and behind shutters throughout Kerrville. Colony size peaks in late summer and the wasps become more defensive around the nest as the season advances. |
| Mice | September through March | Fall temperature drops drive house mice and deer mice into Kerrville homes from the surrounding cedar woodland. Properties at the Hill Country's rural-residential edge have the highest fall entry pressure. |

Kerrville residents encounter pests that most urban Texans never see at home. The striped bark scorpion is the most common scorpion in Texas and is particularly well-represented in the Hill Country, where the rocky limestone terrain creates natural harborage throughout the surrounding environment. Scorpions enter homes through the same gaps used by insects: weep holes in brick veneer, utility penetrations, expansion joints, and poorly sealed door thresholds. They are nocturnal and hide in dark, dry spaces during the day, which is why they turn up in shoes, folded towels, and clothing stored low in closets. Annual exclusion inspections and residual treatment around entry points keep scorpion incursions manageable. The Texas redheaded centipede can reach 6 to 8 inches in length and delivers a bite that produces significant localized pain and swelling. It is not commonly encountered indoors but is found regularly under rocks, wood, and debris in Hill Country yards.
Fall mouse entry from the cedar woodland
The cedar-oak woodland surrounding Kerrville sustains deer mice and house mice at densities that press hard against residential structures when fall temperatures drop. Deer mice in the Hill Country are associated with hantavirus pulmonary syndrome, a serious respiratory disease transmitted through contact with deer mouse urine, droppings, or nesting material. This is not a reason for panic but it is a reason to take fall exclusion seriously and to use proper precautions when cleaning enclosed spaces that have been seasonally unused, including vacation cabins, sheds, and garages that were closed through summer.
How to keep pests out in Kerrville
- ▪Seal foundation weep holes, utility penetrations, and door threshold gaps before scorpion active season begins in March.
- ▪Shake out shoes and check bedding and low-stored clothing during scorpion season from spring through fall.
- ▪Remove rock piles, wood stacks, and dense ground cover directly adjacent to the home to reduce centipede and scorpion harborage zones.
- ▪Before cleaning an enclosed structure such as a shed or cabin that was unused through summer, ventilate and wet-clean rather than dry-sweep to reduce hantavirus exposure risk from deer mouse droppings.
Pricing for Kerrville pest control

Common questions from Kerrville
Are striped bark scorpions in Kerrville dangerous?
Striped bark scorpions deliver a painful sting that causes localized pain, numbness, and swelling. Serious systemic reactions are uncommon in healthy adults but can occur in small children, elderly individuals, or those with insect sting allergies. Medical attention is appropriate for stings in children under 6. The sting is rarely life-threatening in adults but is significantly more painful than most insect stings. Annual exclusion treatment is the standard management approach for Kerrville properties.
What is the large orange and black centipede I found in my Kerrville yard?
That is almost certainly the Texas redheaded centipede (Scolopendra heros), the largest centipede in North America. Adults range from 6 to 8 inches, are reddish-orange with black legs, and are predators of insects, small lizards, and rodents. Their bite causes localized pain, swelling, and occasionally nausea. They are not aggressive toward humans but will bite defensively if handled or accidentally stepped on. They are common throughout the Texas Hill Country.
Should I be worried about hantavirus in Kerrville?
Deer mice, the primary carrier of hantavirus pulmonary syndrome, are present in the Hill Country surrounding Kerrville. Hantavirus is transmitted through inhalation of dust contaminated with deer mouse droppings, urine, or nesting material, not through bites. The risk is most relevant when cleaning enclosed spaces that have been unused for months, such as sheds, cabins, and garages. Proper precautions include wearing gloves and an N95 mask, wetting contaminated material before cleaning, and ventilating the space first.
How are Kerrville's pests different from San Antonio?
Kerrville's semi-arid Hill Country environment shifts the pest emphasis significantly compared to San Antonio. Scorpions are much more common in Kerrville than in the San Antonio urban core, large centipedes are a Hill Country feature, and mice from the surrounding cedar woodland are the dominant fall pest. San Antonio has more German cockroach pressure in its commercial and multi-family housing stock, heavier subterranean termite activity in its older neighborhoods, and less scorpion exposure in most residential areas. The two cities are 60 miles apart but operate in meaningfully different pest environments.
How do I keep wasps off my Kerrville porch?
Paper wasps in Kerrville build new nests each spring under eaves, in porch ceilings, behind shutters, and in any sheltered corner. Removing nests early in the season, before the colony is large, is much safer than tackling a mature nest in late summer when the colony is most defensive. A licensed pest professional can treat nesting sites with residual insecticide in early spring to discourage queens from establishing in the same locations. Nest-prevention mesh in eave gaps reduces available nesting sites.
