Dallas has a long ant season, and the ants vary by block. A lawn in Lake Highlands may be dotted with fire ant mounds, a tree-filled yard in Lakewood may have a carpenter ant colony in an old oak, and an Uptown condo may battle tiny kitchen ants coming up through the plumbing chase. Each situation demands a different fix.
Species to know in the metroplex
Red imported fire ants are the most notorious. They build dome mounds in lawns, around sprinklers and in flower beds, and sting in large numbers if disturbed. Carpenter ants excavate damp or decaying wood in trees, fences, decks and wall voids. Pavement ants nest under sidewalks and patios, while odorous house ants and ghost ants invade kitchens and bathrooms. Argentine ants form large trailing colonies near moisture and gardens. Rover ants, tiny and dark, show up in huge numbers after rain.
What tips you off
- Fluffy mounds in lawn or beds: fire ants.
- Piles of wood shavings under trees, decks or window frames: carpenter ants.
- Tiny trails across counters and bathroom tile: odorous house or ghost ants.
- Large numbers of dark ants emerging from a crack after storms: rover or pavement ants.
- Dead trees or stumps nearby with rustling noises: possible carpenter ant nest.
The professional approach
A provider identifies the ant, finds the trail and checks for conducive conditions such as moisture and tree contact. Fire ant programs combine broadcast bait over the whole lawn with mound-by-mound treatment, repeated through the season. Kitchen ants are treated with gel baits and sealing. Carpenter ant work centers on locating the parent nest and satellites, treating them, and correcting the moisture source. A perimeter treatment applied around the foundation helps prevent new colonies from moving in.
Dallas clay soil shrinks and swells, opening cracks along slabs. Sealing these cracks and keeping sprinklers off the foundation takes away easy access.
Prevention
- Treat fire ant mounds early, especially near play areas.
- Cut tree limbs and shrubs away from roofs and walls.
- Repair roof, gutter and plumbing leaks that wet wood.
- Store food in sealed containers and clean pet bowls daily.
- Keep mulch thin and away from the slab.
- Remove stumps and dead wood from the yard.
Timing matters in North Texas. Fire ant mounds are most visible after spring and fall rains, while carpenter ants swarm in spring, and kitchen ants surge in summer when outdoor food runs short. White Rock Lake neighborhoods with large trees see more carpenter ants, while newer suburban lawns in Far North Dallas are prime fire ant territory. Condo and townhome owners should coordinate with their association so common-area landscaping is treated at the same time as the units.
Stings and safety
Fire ant stings cause painful blisters, and some people react strongly. Move children and pets away from mounds. If someone develops swelling, hives or breathing trouble after a sting, seek medical help immediately.

Ant questions in Dallas
Why do fire ants return after treatment?
New colonies move in from nearby lawns. Ongoing treatment keeps numbers manageable.
Do carpenter ants destroy houses?
They weaken damp wood over time but do not consume it. Fixing the moisture and treating the nest limits damage.
Do ants come in when it rains?
Yes. Flooded nests push colonies into houses, especially after Dallas thunderstorms.
Are natural remedies effective?
They may deter a few ants but seldom eliminate the colony.
