McKinney's rapid development is bulldozing decades-old fire ant colonies out of farmland — and straight into your new yard. The Blackland Prairie clay and disturbed construction sites across north Collin County create perfect conditions for Solenopsis invicta to establish massive colonies in residential landscapes. Romex uses a proven two-step approach: broadcast bait to collapse the colony network, followed by targeted mound treatments for immediate knockdown.

Red imported fire ants (Solenopsis invicta) are the most common outdoor pest complaint across McKinney and north Collin County. The combination of disturbed construction sites, irrigated lawns, warm clay soils, and mild winters creates an ideal breeding environment — fire ant colonies can reach 250,000 workers in optimal conditions.
McKinney's explosive growth compounds the problem. When farmland is graded for development in Trinity Falls, Painted Tree, Erwin Farms, and along the US-380 corridor, established colonies are disrupted but not eliminated. They fragment and re-establish in adjacent yards, parks, and commercial properties. New sod installation with imported soil further introduces colonies.
The health risk is real: fire ant stings cause painful welts in most people and potentially life-threatening anaphylaxis in those with venom allergies. Children, elderly residents, and pets are most vulnerable — especially in high-traffic areas like Bonnie Wenk Park, Towne Lake Recreation Area, and McKinney's extensive trail system along Wilson Creek.
Individual mound treatments are a losing battle — fire ant colonies simply relocate. Our two-step method eliminates existing colonies and prevents reinvasion from neighboring properties.
We apply professional-grade granular bait across your entire yard — not just visible mounds. Fire ant foragers carry the bait back to the colony and feed it to nestmates and the queen through trophallaxis. In McKinney's irrigated landscapes, we time applications for dry periods when foraging activity peaks (early morning or late afternoon).
48–72 hours after broadcast bait, we return to treat remaining active mounds with a targeted drench or dust. This catches colonies that were deep underground during the bait phase. In North Collin County, we pay particular attention to mounds along fence lines, sidewalk edges, and irrigation valve boxes where colonies concentrate.
We establish a residual barrier around your property's perimeter to intercept migrating queens after mating flights. In McKinney, spring and fall mating flights produce thousands of newly mated queens looking to establish colonies — perimeter defense is what prevents reinfestation from neighboring properties and common areas.
Fire ant control is ongoing, not one-and-done. Our technicians return on a scheduled cadence to inspect for new mound activity and reapply treatments as needed. We track activity patterns across North Collin County to anticipate seasonal surges — typically March–May and September–November in North Texas.
Fire ant mounds appear rapidly after rain events — sometimes overnight. In North Collin County's clay soils, mounds can reach 18 inches tall and extend 2–3 feet underground. What you see above ground is just the top of a much larger colony structure.
Unlike native ant species, red imported fire ants swarm aggressively when their mound is disturbed — climbing vertically and stinging simultaneously. If you see ants pouring out of a mound within seconds of contact, they are almost certainly fire ants.
Fire ants are attracted to electrical fields. In our experience across North Collin County, we frequently find colonies in transformer boxes, irrigation valve housings, and AC disconnect switches. This can cause equipment failure and creates a sting hazard for service technicians.
Fire ants follow structural edges — sidewalks, driveways, fence lines, and garden borders. If you see a steady line of small reddish-brown ants along these features, the colony is nearby. We've found that McKinney properties with extensive hardscaping often have more concentrated colony activity along these pathways.
A single property can host 10–20+ fire ant colonies, especially in North Collin County's warm climate. If you see three or more mounds, broadcast treatment is far more effective than treating individual mounds — the colonies you can't see outnumber the ones you can.
Fire ant colony activity disrupts grass root systems, creating circular dead patches around mounds. In irrigated lawns, these patches may appear as areas where grass thins or yellows despite adequate water — the underground tunneling has damaged root contact with soil.
Fire ants are active year-round in McKinney, but peak mound-building activity occurs March–May and September–November. After heavy rains, you may see dozens of new mounds appear overnight as colonies push soil to the surface for ventilation.
Individual mound treatments only address colonies you can see. Fire ant colonies relocate when disturbed and new queens establish colonies after mating flights. Broadcast bait treatment across the entire property — not just visible mounds — is the only effective approach.
Yes. Fire ant stings deliver venom that causes painful, pustule-forming welts. Young children and small pets are at highest risk because they may not recognize or avoid mounds. Approximately 1% of the population is allergic to fire ant venom and can experience anaphylaxis.
Step one: broadcast bait across the entire yard so foragers carry it back to every colony — including ones you can't see. Step two: 48–72 hours later, targeted drench or dust treatment on remaining active mounds. This combination achieves 90%+ colony elimination versus 30–40% with mound-only treatment.
