Out on the Cross Timbers, ants are as much a part of the landscape as live oaks and prairie grass. Fort Worth yards host fire ants, harvester ants and a rotating cast of kitchen invaders, and the species you face will influence whether you spend your weekend raking mounds or sealing window frames.
Ant species around Tarrant County
Red imported fire ants dominate irrigated lawns, building mounds that can appear overnight after rain. Texas harvester ants live in cleared circles on drier, rocky ground along the western and southern edges of the city. Pavement ants, odorous house ants and ghost ants invade kitchens and bathrooms. Carpenter ants live in damp or decayed wood, often in older oak trees and wall voids in the historic neighborhoods. Argentine ants form long trails in areas with steady moisture and garden plants.
What to look for
- Loose, domed mounds with no visible opening: fire ants.
- A cleared circle with a central crater: harvester ants.
- Tiny pale ants in bathrooms and near sinks: ghost ants.
- Wood shavings pushed from small holes: carpenter ants.
- Thick trails along a wall base or fence: Argentine or pavement ants.
The professional approach
A licensed provider identifies the ant, locates the entry points and examines the surrounding yard. Fire ant programs combine broadcast bait across the lawn with direct mound treatment, repeated through the warm months because colonies re-establish quickly. Harvester ant mounds are treated individually. Kitchen ants are managed with baits, caulk and moisture fixes. For carpenter ants, the technician finds the nest, treats it and recommends repairs for leaks and rot. Limestone and clay soils often have deep cracks that serve as nest entrances, so sealing and grading help.
On acreage or horse properties, ant control extends to barns, feed rooms and fence lines, where sweet feeds and spilled grain attract foragers.
Prevention
- Treat fire ant mounds early and avoid disturbing them.
- Trim vegetation off the house and keep mulch thin.
- Repair leaks at roofs, gutters, hose bibs and AC lines.
- Seal food, wipe spills and clean pet dishes daily.
- Caulk cracks in foundations, window frames and door thresholds.
- Remove dead trees, stumps and old fence posts from near the home.
Timing is important in Fort Worth. Fire ant mounds peak after spring and fall rains, kitchen ants surge in the heat of July and August when outdoor food is scarce, and carpenter ants swarm in spring. Homeowners in Fort Worth neighborhoods like Ridglea, Westover Hills and Tanglewood, with big lots and mature trees, see more carpenter ants and fire ants than townhome owners do, while apartment dwellers mostly meet the small kitchen species.
Safety
Fire ants and harvester ants sting. Keep children and pets away from mounds. Anyone with signs of a severe reaction, such as trouble breathing, widespread hives or swelling of the face, needs immediate medical care.

Ant questions in Fort Worth
Why do I have so many mounds after rain?
Fire ants relocate when nests flood, and wet soil is easy to dig. New mounds can appear within a day.
Are harvester ants dangerous?
Their sting is painful and can be serious for allergic people. Treat their mounds with care or call a pro.
How can I prevent ants from entering the house?
Seal cracks, keep food stored, and trim plants away from the walls.
Do ants come inside in winter?
Mild days bring them out, and indoor nests keep going. Winter sightings deserve attention.
