Ant control in Lancaster, TX means two different jobs. Out in the yard it's the red imported fire ant, the species that turns a lawn into a minefield of mounds after every rain and stings anything that disturbs it. Indoors it's odorous house ants and pavement ants, the tiny ants streaming across the counter and the bathroom sink hunting water when a North Texas summer bakes the soil dry. Both live in colonies you can't see, which is why spraying the mound or the trail rarely fixes anything, and with fire ants can actually split the colony and make it worse. An experienced local exterminator baits the colony and treats the yard as a whole.
Fire ants and the Texas yard
Red imported fire ants thrive in exactly the conditions Lancaster provides: sunny open turf, heavy clay that holds a mound's shape, and a long warm season. Mounds appear overnight after rain because the colony is pushing soil up out of a flooded gallery. Knock the mound down and the colony simply rebuilds; drench one mound and the survivors often bud off into several new ones nearby.
The reliable approach is a two-step: a yard-wide slow-acting bait that foragers carry down to the queens, followed by direct treatment of individual mounds that remain. Timing matters, ants have to be actively foraging for bait to work.
House ants indoors
Odorous house ants (they smell faintly of coconut when crushed) and pavement ants nest outdoors under stone, mulch, pavers, and along the slab, then trail indoors for water and sugars, especially when the summer heat dries the soil out. Repellent sprays scatter them and can split the colony into more nests.
Baiting works because foragers carry it back and share it. Add a non-repellent exterior perimeter, seal the entry points around the slab edge, windows, and utility lines, and cut the moisture at the foundation, and the pressure drops.
