Brownsville's hot, humid weather keeps ants busy most of the year. Fire ants build mounds in irrigated lawns, small trailing ants invade kitchens, and after the heavy rains the Valley is known for, colonies of all kinds surface and move indoors. If you have felt the sting of a fire ant while watering the yard, you already know why many homeowners schedule regular treatments.

Ants common in South Texas
- Red imported fire ants. Build mounds in lawns, parks and along resaca banks. Their stings are painful and can cause serious reactions in some people.
- Crazy ants. Fast-moving ants that can appear in huge numbers and are known in parts of the Texas Gulf Coast. They may nest in electrical equipment.
- Ghost ants and pharaoh ants. Tiny ants that nest in wall voids, potted plants and kitchens.
- Harvester ants. Large ants that clear bare patches around their nests in dry, sandy soil.
- Carpenter ants. Nest in damp wood, including old palm stumps and leaky eaves.
Why they flourish here
Heat, frequent irrigation and Gulf storms keep soil damp, creating ideal conditions for ant colonies. Heavy rain floods nests and pushes ants into wall voids, garages and air conditioning units. During dry spells, they come inside seeking water. Thick landscaping, including hedges and palms, provides shelter and a route to the house. Sugary fruit from citrus trees and honeydew from landscape insects supply food, while pet bowls and trash cans provide protein and fat. Homes built on slabs have cracks and expansion joints where trails emerge indoors.
How professionals tackle ants
For fire ants, a typical program includes broadcast bait across the lawn, individual mound treatments near walkways and play areas, and follow-up applications. For crazy ants and ghost ants, providers use specialized baits, dusts in voids and non-repellent perimeter products. Technicians also inspect electrical boxes, meters and A/C units, where ants like to nest. Because colonies are large and conditions favor rapid recovery, repeat visits are standard in Brownsville, and many homeowners keep a monthly or bi-monthly schedule through the warm season.
What you can do
- Avoid disturbing mounds, and keep children and pets away.
- Fix leaky hoses, sprinkler heads and outdoor faucets.
- Trim vegetation off the walls, and keep mulch thin.
- Store pet food in sealed containers and rinse bowls.
- Seal gaps where pipes, wires and cables enter the home.

Reading the seasons in the Valley
Ant activity builds in spring as temperatures climb and peaks during the long summer. After storms, expect mounds to appear within a day or two. Cooler weeks in winter slow foraging, but warm days bring colonies back to the surface, so the quiet period is short.
