Common San Antonio Pests and Treatment Costs
Fire ants ($150 to $400)
Red imported fire ants are the most persistent pest across the San Antonio metro. They build mounds in virtually every yard, park, and open space, with large, aggressive colonies that sting anyone who disturbs them. Fire ant mounds appear quickly after rain, especially in the clay and limestone soils common throughout the area. Mounds frequently appear along foundations, in flower beds, around AC units, and in playground areas.
Treatment costs $150 to $400 for a full yard application. Broadcast bait treatments applied twice yearly (spring and fall) provide the best ongoing control. Individual mound treatments offer faster results for specific mounds but do not prevent new colonies from establishing. Fire ants cannot be permanently eliminated in San Antonio; they recolonize continuously from surrounding areas. See our ant exterminator cost guide.
Termites ($1,200 to $3,500)
Subterranean termites are a significant structural threat across the San Antonio area. The warm climate and alternating wet/dry cycles in Central Texas create conditions where termite colonies thrive. Older homes in established neighborhoods like Alamo Heights, Monte Vista, Tobin Hill, King William, and Terrell Hills are particularly vulnerable due to mature trees, aging foundations, and pier-and-beam construction.
Treatment costs $1,200 to $3,500 for a typical home. Liquid barrier treatment is the most common approach. Annual termite inspections ($75 to $125) are recommended. Texas real estate transactions commonly require a WDI report. See our termite treatment cost guide.
Scorpions ($150 to $350)
Striped bark scorpions are common in areas west and northwest of San Antonio where the city meets the Texas Hill Country. Neighborhoods in Helotes, Boerne, Fair Oaks Ranch, the Dominion, and the northwest side (Stone Oak, TPC area) have the highest scorpion activity. Rocky, limestone terrain provides natural habitat, and scorpions enter homes through gaps under doors, around pipes, and through weep holes in brick construction.
Treatment costs $150 to $350 and includes perimeter spray, dust application around entry points, and sealing gaps. Most general pest control plans in scorpion-prone areas include scorpion treatment. Monthly service is recommended for homes with consistent scorpion activity.
Cockroaches ($100 to $575)
German cockroaches are the primary indoor cockroach species in San Antonio, infesting kitchens, bathrooms, and apartment complexes. American cockroaches (large "water bugs") enter from sewer systems and through gaps, especially after heavy rains. Smoky brown cockroaches are common outdoors and enter through weep holes in brick construction, which is prevalent throughout San Antonio.
Treatment costs $100 to $575 depending on species and severity. German cockroach infestations require the most intensive treatment with gel baits, IGR (insect growth regulators), and multiple follow-up visits. Perimeter treatments control outdoor species. See our cockroach exterminator cost guide.
Mosquitoes ($150 to $375)
San Antonio has significant mosquito pressure from March through November. Heavy rains in spring and early fall create standing water in low-lying areas, retention ponds, and poorly drained yards. The San Antonio River, Salado Creek, Leon Creek, and Medina River corridors provide extensive mosquito breeding habitat.
Monthly barrier spray services ($50 to $85/month) provide the best protection during the nine-month mosquito season. One-time treatments cost $150 to $375. The city of San Antonio also conducts mosquito surveillance and targeted spraying in response to West Nile virus detections.
Rodents ($200 to $600)
Mice and rats are a year-round concern in San Antonio, with activity peaking in fall and winter as rodents seek indoor shelter. Older neighborhoods with mature trees (Monte Vista, Alamo Heights, Olmos Park) have higher roof rat populations. Norway rats are found near commercial areas and waterways. House mice enter through surprisingly small gaps in foundations and around utility penetrations.

| Winter | Dec – Feb | Rodents, cockroaches | Mild San Antonio winters mean pest activity never fully stops. Rodents are the primary indoor concern. |
Cost Factors in San Antonio
- Hill Country vs city location. Homes on the northwest side near the Hill Country (Helotes, Boerne, Stone Oak) face higher scorpion pressure that may require monthly service. Homes closer to downtown and the east side have more termite and cockroach issues.
- Brick construction with weep holes. Brick homes are common throughout San Antonio. Weep holes (drainage gaps in the brick mortar) are a primary entry point for cockroaches, scorpions, and other pests. Screening weep holes is an important preventive measure.
- Lot size. San Antonio has everything from small urban lots near downtown to large properties on the outskirts. Larger lots cost more for fire ant and mosquito treatments.
- Home age. Older homes in Alamo Heights, Monte Vista, and King William have more pest entry points and are more susceptible to termites and rodents than newer construction in areas like Cibolo, Schertz, and New Braunfels.
- Proximity to creeks and rivers. Homes near Salado Creek, Leon Creek, the San Antonio River, and the Medina River have higher mosquito and rodent pressure.
Choosing a Pest Control Company in San Antonio
- Verify Texas licensing. Texas requires pest control operators to be licensed by the Texas Department of Agriculture (TDA), Structural Pest Control Service.
- Ask about scorpion experience. If you live in a scorpion-prone area, choose a company with specific experience treating striped bark scorpions and sealing common entry points in brick construction.
- Get at least three quotes. San Antonio has a competitive pest control market with many local and national companies.
- Confirm fire ant re-treatment policy. Since fire ants are unavoidable in San Antonio, ask whether the plan includes re-treatment for fire ants between scheduled visits.
