Red Imported Fire Ant Control in Fair Oaks Ranch, TX
Fire ants usually make themselves known in Fair Oaks Ranch right after a good rain: low, fluffy mounds of worked soil appear in the yard, and reddish ants of mixed sizes boil out and climb anything that touches them. Don't kick the mound or pour a home remedy on it. Either follow AgriLife's two-step baiting plan for the whole yard, or have a technician treat the mounds around your house.

Three counties, one quarantine #
Fair Oaks Ranch is split among Bexar, Kendall and Comal counties, and all three appear on the Texas Department of Agriculture's list of counties quarantined for imported fire ants (TDA). Whichever side of a county line your house is on, the same rules apply.
The quarantine matters when material leaves the area. TDA requires a certificate or permit to move these things out of quarantined territory:
- soil, and plants with roots in soil
- sod
- baled hay or straw that was stored on the ground
- used soil-moving equipment
If you're shipping plants or hauling dirt or hay beyond the quarantined area, check with TDA first.
After a flood, check the house, not just the yard #
City memos from fall 2026 note a generator damaged during the July flooding event (Manager's Weekly Memo). High water affects fire ants too. AgriLife's Fire Ant Project says whole colonies may move indoors during floods, and that mounds are easiest to spot after heavy rain. The ants also forage inside for food and moisture during hot, dry summer months.
After a big storm, walk the yard for new mounds, then look along baseboards and the slab edge for ant trails.
Ants in the AC unit or meter box #
Air conditioners and electrical boxes give fire ants warmth and dry shelter, and the ants chew insulation and cause shorts. Texas A&M's ENTO-020 covers the problem, and AgriLife puts the yearly cost to Texas electrical equipment at $11.2 million.
If ants are packed into your condenser or a box, turn off the power and leave treatment to an electrician or a licensed pest professional. Never spray or drench inside electrical equipment.
Fire ant or a native ant? #
Workers run from 1/16 to 3/16 inch and are reddish brown, and one colony contains workers of many sizes. Disturbed workers race up vertical surfaces like a stick or your leg, something few native ants do. The mound has no opening at the top. AgriLife says the state's three native fire ants are milder by comparison.
A homeowner plan that works, and remedies that don't #
For a whole yard, AgriLife recommends its Two-Step Method:
- Spread bait across the entire yard on a day when the grass is dry, no rain is due for 24-48 hours, and the ants are out foraging; if they're carrying bait off within 30 minutes, the timing is right.
- Treat individual problem mounds near doors, walks and play areas.
Bait should be fresh and never watered in, and patience is required: AgriLife expects 80% to 90% control only after weeks to months. The Two-Step page suggests a fall broadcast between late August and mid-October, and L-5070 says May through September is the time to bait for most of Texas, in the evening once daytime soil tops 90 °F.
What doesn't work: Texas A&M's ENTO-009 says baking soda, cinnamon, club soda, coffee grounds, grits and molasses failed to document control. About 3 gallons of hot water per mound kills roughly 60% of mounds, and it kills any plants it touches.
When is a sting more than a nuisance? #
A sting burns and itches, and a white pustule forms in a day or two. It can last a week or more, gets infected easily and may leave a scar. Brush ants off fast; they grip the skin with their jaws.
Slurred speech, chest pains, breathlessness, serious swelling, nausea or heavy sweating after stings mean a trip to an emergency facility now. Anyone who reacts strongly should see an allergist, and AgriLife notes the Two-Step approach may not suit a home with a highly allergic person.
