Ant control in Denton, TX usually covers two separate problems: red imported fire ant mounds in the yard and smaller ants trailing into kitchens and bathrooms. Pest Renewal connects you with a licensed technician who identifies which ants you have, treats the yard with baits and targeted mound treatments, and goes after indoor colonies at the source.
Fire ants are established across the Denton area and much of eastern and central Texas, and their mounds often reappear after heavy rain. Pest Renewal handles ant calls across Denton, Midland, and Waco — call and tell the specialist where you’re seeing them.

Signs You Need Professional Ant Control in Denton
A few ants on the patio is normal Texas living. These signs point to established colonies that store-bought products usually won’t reach.
Fire ant mounds in the lawn
Loose mounds of worked soil with no opening on top, usually in sunny spots, along sidewalks, or against the slab.
Ant trails on countertops
A steady line of small ants between a crack and the sugar canister or pet bowl means a colony has found food.
Sting pustules on ankles
Fire ant stings typically turn into itchy white pustules. Regular stings during ordinary yard use mean mound pressure is too high.
Sawdust-like piles indoors
Coarse debris below window frames or trim can mean carpenter ants are excavating damp wood nearby.
Winged ants inside
Winged ants emerging indoors suggest a colony nesting within the structure. They closely resemble termite swarmers, so get them identified.
Ants inside the AC unit
Fire ants pack soil into outdoor air conditioners and electrical boxes and can chew insulation, which may short out switches.
How Ant Control Works
Ants are treated differently depending on species and nest location, so identification always comes first.
Identify the ant
Describe the ants’ size, color, and location on the call. The technician confirms the species on site, since each needs a different treatment.
Yard and perimeter inspection
The technician looks for mounds, foraging trails, nests under mulch and stones, and slab entry points.
Broadcast bait across the yard
For fire ants, granular bait is spread across the lawn while ants are foraging. Workers carry it into the colony, where it reaches the queen.
Treat problem mounds
Mounds near walkways, play areas, and doors get individual treatment for faster relief.
Indoor colony treatment
Inside, baits and crack-and-crevice applications let workers carry product back to the nest.
Follow-up visit
A return visit checks results and handles new mounds that move in from neighboring yards.
What Affects the Cost of Ant Control?
A few kitchen trails and a lawn dotted with fire ant mounds are very different jobs, so no single price fits both. The specialist will explain what affects your cost before scheduling.
Lot size
Broadcast bait covers the whole treated area, so a bigger yard means more product and time.
Which ants you have
Fire ants, carpenter ants, and sweet-feeding ants need different products, and carpenter ant nests may hide inside walls.
Yard, house, or both
Outdoor fire ant work is a separate scope from interior service, and many homes need both. Ask about pairing yard baiting with mosquito control.
One-time versus recurring service
Fire ants recolonize from surrounding land, so seasonal coverage is priced differently from a single visit.
Number of colonies
Dozens of mounds or a colony spread through several wall voids takes more material and follow-up.
How Do You Get Rid of Fire Ants in a Texas Yard?
Texas A&M AgriLife recommends the Two-Step Method: broadcast a fire ant bait across the whole yard, then treat individual mounds that cause problems. Bait reaches colonies you can’t see, including young ones too small to build mounds. Treating mounds one at a time misses those hidden colonies, and a mound that isn’t fully eliminated can simply relocate nearby.
Baits work best in spring and fall, when ants are actively foraging. Texas A&M notes fire ants forage when soil surface temperatures are between 70 and 90°F, so hot-weather baiting moves to the evening, and bait shouldn’t go down when rain is expected within eight hours. Coordinate with neighbors when possible, since ants move freely between yards.
Before the technician arrives
Don’t rake, kick, or drench mounds before a bait treatment, and skip spraying indoor trails. Disturbed colonies move, and wet bait loses its appeal, so hold off on irrigation around the appointment.
Are Fire Ant Stings Dangerous?
For most people, fire ant stings are painful and itchy but not dangerous. When a mound is disturbed, workers swarm up legs and other vertical surfaces, biting and stinging almost at once, and the stings usually form white pustules. Anyone with shortness of breath, a thickening tongue, or heavy sweating after stings needs medical help immediately.
Small children and pets face the most risk, so mounds near play areas, dog runs, and doorways come first. For seasonal patterns, read our guide to fire ants in Texas lawns.
Which Ants Invade Homes in Texas?
Several species regularly come inside Texas homes. Odorous house ants are small, dark ants that give off a distinctive smell when crushed and trail to sweets. Carpenter ants are large ants that nest in damp or damaged wood. Pharaoh ants are tiny and yellowish. Even fire ants, which nest outdoors, forage indoors in late summer for food and water.
- Odorous house ants nest under mulch, stones, and inside wall voids.
- Carpenter ants excavate wood without eating it and usually signal a moisture problem.
- Pharaoh ants can split into new colonies when sprayed, so they need specialized baiting.
Because carpenter ant damage can resemble termite damage, your technician may recommend a termite inspection when wood is involved. Indoor ant service also pairs well with a quarterly pest control plan, which renews the perimeter treatment that keeps new colonies out.

Ant Control FAQs
How long does fire ant bait take to work?
Texas A&M puts the fastest fire ant baits at about 2 to 4 weeks, while baits built on insect growth regulators take 2 to 6 months but tend to suppress colonies longer. Mounds near high-traffic spots can be treated individually for quicker relief while the broadcast bait works.
Can fire ants be eliminated from a yard permanently?
Not permanently. Fire ants are established across much of Texas, and new colonies arrive after mating flights or spread from neighboring yards and open land. Texas A&M’s approach is ongoing suppression: broadcast baiting once or twice a year plus spot treatment of new mounds. Coordinated treatment across a neighborhood or HOA keeps numbers down longer.
Why do more ant mounds appear after it rains?
Dry, hard soil keeps fire ants from building above ground, so colonies nest deeper and stay out of sight during droughts. Once rain softens the ground, they rebuild mounds quickly. A sudden crop of mounds after a storm usually means the colonies were already in the yard, not that they all arrived overnight.
Do you treat fire ants in Midland and Waco?
Yes. Pest Renewal takes ant calls in Waco and Midland as well as Denton. Red imported fire ants are well established around Waco. In West Texas, Texas A&M notes the imported fire ant occurs only in some areas and native fire ant species may be common, so identification comes first in Midland.
