San Antonio Pest
Intelligence Hub
More than numbers. Real treatment data from our FieldRoutes system, combined with research from Texas A&M AgriLife Extension, the CDC, and the EPA — translated into what it actually means for San Antonio homeowners and businesses.
Serving Since 2016 · Locally Managed & Operated
Spring Is the Most Critical Time for Pest Prevention
Critical AlertTermite swarms, fire ant expansion, and mosquito emergence all converge in San Antonio's spring. Every week without treatment allows exponential population growth.
Year-Round Service Advantage: Year-round customers enter spring with a fresh barrier already in place — no catch-up needed.
June 2026 Forecast for San Antonio
Based on May treatment data, seasonal patterns, and regional pest biology — here's what San Antonio property owners should prepare for.
Summer Heat Drives Pests Indoors and Activity Higher
Critical Threat LevelJune's triple-digit heat pushes scorpions, cockroaches, and ants to seek moisture and shelter inside San Antonio homes and businesses. Mosquito breeding is relentless near any standing water. Termite monitoring remains critical.
Top Threats for June
Peak indoor entry — homes near natural areas see highest activity
Population peaks with sustained heat and any rainfall
Fire ants and carpenter ants at maximum colony size and activity
Why Year-Round Service Matters Now
June separates maintained properties from vulnerable ones. Without a current barrier, scorpions and ants exploit every unsealed gap in your structure.
Research Note: Texas A&M AgriLife Extension advises that the striped bark scorpion is most active from May through August in Texas, with peak indoor entry occurring during the hottest periods.

Rising Threats — What This Means for You
4 risingThese pests are increasing. Here's what the data means for your home or business, backed by research.
Mosquitoes
Specialized TreatmentFor Homeowners
Austin's proximity to waterways including Lady Bird Lake, Barton Creek, and hundreds of neighborhood retention ponds creates a persistent mosquito pressure zone. These aren't just nuisance biters — the CDC has confirmed West Nile virus transmission in Travis County.
For Businesses
Outdoor dining areas, event venues, fitness centers with outdoor space, and hospitality properties face direct revenue impact from mosquito activity. Guest complaints spike during peak season, and businesses near water features face sustained pressure without regular treatment.
Health Risks
- •West Nile virus — confirmed cases in Travis County (CDC data)
- •Zika virus — carried by Aedes aegypti mosquitoes present in Austin
- •Chikungunya and Dengue — CDC-monitored transmission risks in Texas
Property Risks
- •Reduces outdoor living space usability
- •Impacts property value in areas near standing water
- •Commercial outdoor spaces lose revenue from guest avoidance
“The CDC reports that mosquito-borne disease cases nationwide increased significantly from 2004 to 2016. Texas, and specifically the Austin metro, remains a West Nile virus hotspot. Aedes aegypti mosquitoes — vectors for Zika, Dengue, and Chikungunya — have established populations in Travis County.”

Ants
For Homeowners
Rising ant treatments indicate active colony expansion in Austin neighborhoods. Fire ants can deliver painful stings that cause allergic reactions, and carpenter ants silently hollow out structural wood. Scout ants visible indoors almost always mean a much larger colony is nesting nearby.
For Businesses
For restaurants, food service, and office buildings, ant activity is a health-code liability. A single ant trail in a commercial kitchen can trigger a failed inspection. Proactive perimeter treatment is a business continuity measure, not a luxury.
Health Risks
- •Fire ant stings cause anaphylaxis in sensitized individuals
- •Fire ant mounds near playgrounds and pet areas pose injury risk
- •Ants contaminate food preparation surfaces
Property Risks
- •Carpenter ants damage structural wood framing
- •Fire ant mounds damage lawns, irrigation systems, and electrical equipment
- •Ant colonies inside walls can compromise insulation
“Texas A&M AgriLife Extension identifies the red imported fire ant (Solenopsis invicta) as one of the most significant invasive pests in Texas. A single colony can house 200,000–500,000 workers, and Austin's warm climate allows year-round colony activity with peak expansion in spring and fall.”

Crickets
For Homeowners
Cricket invasions in Austin are one of the most common late-summer nuisance complaints. While not a direct health threat, large cricket die-offs inside homes produce a foul odor, and cricket droppings stain light-colored surfaces. They are attracted to exterior lighting at night.
For Businesses
Retail storefronts, restaurants, and any business with illuminated signage experience massive cricket congregations in late summer. Accumulated dead crickets at entrances and in vestibules create an unsanitary appearance and slippery walking surfaces.
Health Risks
- •No significant health risks
- •Large die-offs produce unpleasant odor
- •Droppings may trigger mild allergic reactions in sensitive individuals
Property Risks
- •Cricket droppings stain fabrics, wallpaper, and painted surfaces
- •Large numbers damage stored textiles and paper goods
- •Accumulated dead insects at commercial entrances create slip hazard
“Texas A&M AgriLife Extension documents that Central Texas experiences annual field cricket migrations in late summer (August–September) driven by population cycles and declining habitat quality. Switching exterior lighting to sodium vapor or yellow "bug lights" reduces attraction by up to 80%.”
