Collinsville, Texas is a small town in southwestern Grayson County, situated near the intersection of U.S. Highway 377 and FM 902. The city is close to Lake Ray Roberts, providing residents with recreational opportunities such as fishing and boating. Collinsville’s historic downtown features early 20th-century buildings, and the community is known for its annual Peanut Festival celebrating the area’s agricultural heritage.
Collinsville sits within the northern edge of the Texas Blackland Prairies ecoregion, characterized by gently rolling terrain and fertile clay soils. The city is located just east of the Elm Fork of the Trinity River and about five miles west of Lake Ray Roberts. These water bodies and the area's open grasslands create habitats favorable for rodents, mosquitoes, and other pests, especially in wet years.
The historic heart of the community featuring older homes and local businesses.
Older structures often have issues with termites and occasional rodent invasions.
Residential area north of the main downtown, with newer homes and open lots.
Open spaces attract field mice and occasional snakes, especially after heavy rains.
Rural properties and homes closer to the lake and parklands.
Higher mosquito pressure and increased tick activity due to proximity to water and woods.
Mix of residential and agricultural properties on the south side of town.
Barns and fields attract flies, wasps, and occasional agricultural pests.
What our licensed technicians see on the ground in Grayson County.
Grayson County sits within a moderate-to-heavy termite pressure zone according to USDA and TPCL mapping. In Collinsville, subterranean species — primarily Reticulitermes flavipes — account for nearly all reported infestations. Downtown Collinsville shows the classic risk profile: older structures often have issues with termites and occasional rodent invasions. Historic structures near Lake Ray Roberts 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: Schedule an annual professional termite inspection; WDO damage in Collinsville typically goes undetected for 3–5 years before visible signs appear.
Grayson County ranks among the most mosquito-pressured areas in the region, thanks to the humid subtropical climate and dense tree canopy that blocks drying airflow after storms. Residents in North Collinsville frequently cite mosquito bites when they request service, especially during morning and evening hours. Vector-borne disease surveillance has confirmed West Nile and rarely EEE in Texas counties, making residual barrier treatments more than a comfort issue. Romex technicians map breeding sites with a property walk before any application.
Prevention tip: Use a dunk-style larvicide (Bti) in any decorative pond, rain barrel, or low spot that can't be drained within a week.
Fire ants arrived in the Gulf region decades ago and have no effective native predators. In Collinsville, mounds tend to cluster along sun-exposed areas: driveway edges, sidewalk cracks, and disturbed soil at property lines. Homeowners in Downtown Collinsville frequently report being stung while gardening. For indoor ant pressure, carpenter ants are the species we are most concerned about because they excavate structural wood; their presence often signals a moisture problem in the wall cavity.
Prevention tip: Never spray a visible ant trail indoors — it scatters the colony. Instead, call a professional to use targeted non-repellent products.
The American cockroach (Periplaneta americana) is the common "water bug" homeowners in Collinsville encounter coming out of drains and sewer lines. Older homes in Downtown Collinsville, where older structures often have issues with termites and occasional rodent invasions., have more frequent sightings. Restaurants and food service near Lake Ray Roberts 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: Eliminate moisture around the foundation: fix splash blocks, grade soil away from the house, and repair any dripping outdoor faucets.

Collinsville has a humid subtropical climate, with average summer highs around 95°F and winter lows near 32°F. Annual rainfall averages about 38 inches, with peak precipitation in spring and early summer. Warm temperatures and moderate humidity encourage rapid insect breeding, while wet periods boost mosquito and ant populations.
The proximity to Lake Ray Roberts and the Elm Fork Trinity River creates standing water areas ideal for mosquito breeding. Fertile prairie soils and surrounding croplands foster populations of ants, beetles, and field mice. Native oaks and pecan trees in town also attract squirrels and occasional wood-boring insects.
Spring rains and warming temperatures bring out termites and ants in Collinsville homes, while mosquitoes and ticks become active near Lake Ray Roberts and along creeks.
Hot, humid conditions increase mosquito and fly activity, especially around water sources and open fields on Collinsville’s outskirts.
Rodents seek shelter indoors as temperatures cool, and spiders and stink bugs are commonly found in homes throughout Collinsville.
