Why Does Sherman, Texas Need Professional Pest Control?
Population: ~45,000 · Grayson County
Sherman, Texas is the county seat of Grayson County, located in North Texas near the Oklahoma border. The city is home to Austin College, one of the oldest colleges in Texas, and is known for its historic downtown square and the nearby Hagerman National Wildlife Refuge. Sherman is also a regional employment hub, with companies like Texas Instruments operating major facilities in the area.
Sherman sits on gently rolling Blackland Prairie terrain, with clay-rich soils that support native grasses and hardwoods. The city is situated near the Red River and is just a few miles south of Lake Texoma, one of the largest reservoirs in Texas. These water bodies, along with the area's mix of urban and rural landscapes, create diverse habitats for local pests.

Sherman Pest Pressures: A Closer Look
What our licensed technicians see on the ground in Grayson County.
Termites in Grayson County
Grayson County sits within a moderate-to-heavy termite pressure zone according to USDA and TPCL mapping. In Sherman, subterranean species — primarily Reticulitermes flavipes — account for nearly all reported infestations. Downtown Sherman shows the classic risk profile: older buildings often face issues with rodents and cockroaches due to aging infrastructure. Historic structures near Austin College often need remedial treatment because earlier pre-construction soil barriers have degraded. Our approach combines quarterly exterior inspections with in-wall boroscope probes wherever mud tubes are suspected.
Prevention tip: Keep mulch, firewood, and landscaping timbers at least 12 inches away from foundation walls and never stack firewood against the house.
Mosquitoes in Grayson County
Mosquito populations in Sherman surge from April through October, driven by heavy spring rainfall and standing water that collects in gutters, bird baths, bromeliad pockets, and drainage ditches. Westwood sees particularly high pressure because tree cover attracts squirrels, ants, and occasional termite activity.. Our service crews have documented heavy activity within 500 feet of Hagerman National Wildlife Refuge, where untreated vegetation provides daytime harborage for Aedes albopictus and Culex quinquefasciatus. We apply In2Care stations and barrier treatments with Talstar P that last up to 30 days per application.
Prevention tip: Walk your property weekly and dump any standing water — a discarded bottle cap can breed 300 mosquitoes in seven days.
Ants in Grayson County
Red imported fire ants (Solenopsis invicta) are the dominant outdoor ant species in Grayson County, forming visible mounds after every significant rain. Turfgrass areas near Austin College can host 50+ mounds per acre during wet springs. Indoors, the picture shifts: odorous house ants, acrobat ants, and — in older wood-framed homes — carpenter ants account for most kitchen and bathroom trails. Downtown Sherman reports trend heavily toward fire ants on the outside and odorous house ants on the interior. Our treatment uses Top Choice fipronil granules outside for season-long fire ant control, plus non-repellent Termidor SC band applications on entry points.
Prevention tip: Never spray a visible ant trail indoors — it scatters the colony. Instead, call a professional to use targeted non-repellent products.
Cockroaches in Grayson County
The American cockroach (Periplaneta americana) is the common "water bug" homeowners in Sherman encounter coming out of drains and sewer lines. Older homes in Downtown Sherman, where older buildings often face issues with rodents and cockroaches due to aging infrastructure., have more frequent sightings. Restaurants and food service near Austin College carry higher overall roach pressure due to dumpster areas. Romex pairs IGR (insect growth regulator) treatments in basements and crawl spaces with Advion gel bait placements in kitchens to break the reproductive cycle.
Prevention tip: Inspect any secondhand appliance (especially microwaves, toaster ovens, mini fridges) before bringing it indoors — German cockroaches hitchhike inside.

Sherman Climate & Pest Activity
Local Climate Impact
Sherman experiences a humid subtropical climate, with average summer highs in the low 90s°F and winter lows in the 30s°F. The city receives about 40 inches of rainfall annually, supporting lush vegetation but also high mosquito and ant activity in wet months. Humidity and warmth foster rapid breeding cycles for many common pests.
Why Sherman Faces Unique Pest Pressures
Sherman's proximity to Lake Texoma and the Red River creates ideal habitats for mosquitoes, especially during wet spring and summer periods. The region's clay soils and prairie grasses support ant colonies and occasional termite issues, while the mix of rural and urban areas brings rodents and wildlife into closer contact with homes and businesses.
Sherman Seasonal Pest Calendar
Spring (Mar-May)
Warm temperatures and increased rainfall lead to swarming termites and the start of mosquito season, especially near Sherman’s creeks and parks. Ants become active in yards and homes.
Summer (Jun-Aug)
Mosquitoes thrive due to high humidity and the proximity to Lake Texoma. Ants and wasps are very active outdoors, and rodents seek shelter in cool indoor spaces.
Fall (Sep-Nov)
As temperatures cool, rodents and spiders look for warmth indoors, especially in older Sherman neighborhoods. Cockroach activity increases as they seek food and shelter.
Winter (Dec-Feb)
Rodents and spiders remain active indoors, particularly in homes near open fields and wooded areas of Sherman. Outdoor pest activity drops but indoor issues persist.
Pro Tip: Sherman homeowners save up to 40% with year-round protection plans that proactively treat for seasonal pests before they become infestations.
