Fire Ant Control Cost & Treatment Guide for Fort Worth
Buffalo Outdoor • May 2026 • Fort Worth, TX
Effective fire ant control uses a combination of broadcast bait applied 2–3 times per year and targeted mound treatments. Annual programs typically run $250–$500 for a residential property. Here is a clear breakdown of what each approach costs and what to expect.
Why Fire Ants Are So Hard to Eliminate
Fire ants are a nightmare from a control perspective because of how their colonies work. A typical mound contains 100,000 to 250,000 individual ants, and the queen lives deep underground — often three feet or more below the surface.
Deep Queens
Surface treatments kill visible workers but never reach the queen. The colony recovers within weeks unless you reach her deep underground.
Multi-Queen Colonies
Polygyne fire ant colonies feature multiple queens across dozens of interconnected mounds. Treating one mound while leaving others does almost nothing to the overall population.
Rapid Re-Infestation
Across Fort Worth, Keller, Aledo, and Benbrook, fire ants are a year-round reality. They spread quickly and aggressively from neighboring properties if not addressed.
Broadcast Bait: The Foundation of a Real Program
The most cost-effective fire ant control on a residential property is a broadcast bait application. Workers find the bait, carry it back to the colony, and feed it to other ants — including the queen. The queen dies, the colony fails, and mounds disappear over 2–4 weeks.
Applications Per Year
2 broadcast applications recommended — one in spring, one in late summer or early fall.
Cost Per Application
$125 to $200 per application depending on lot size.
Annual Program Cost
$250 to $400 for the full annual broadcast bait program.
Bait works on colonies you have not even noticed yet. Application timing matters: best when soil is 60–90°F, lawns are dry, and before expected rain.
Mound Treatments for Visible Problems
How It Works
A drench application uses liquid insecticide poured directly into the mound, saturating down to where the queen lives. Effective treatments kill the entire colony within a few days.
Cost
$50 to $100 for a small residential job. More for larger properties or many mounds. A good complement to broadcast bait — not a substitute.
Key Tip
Do not disturb a mound before treating. Disturbed mounds often relocate the queen before treatment can reach her. Apply the drench gently and let it soak down.
DIY Options: What Works and What Doesn't
Boiling Water
Can kill some workers but rarely reaches the queen. About 60% effective at best — requires 3–5 gallons per mound.
Granular Contact Killers
Kills visible workers but does not reach the queen. Mound appears dead, then comes back in two weeks.
DIY Bait Products
Can work with the same active ingredients as professional bait — but results are inconsistent due to timing, coverage, and application errors.
Home Remedies (Grits, etc.)
The grits myth is thoroughly debunked. Fire ants only consume liquid food. Grits, club soda, and gasoline do not work and some are dangerous.
What a Complete Annual Program Costs
A typical Fort Worth area residential property on a complete fire ant program:
2 Broadcast Bait Applications
$250 to $400 total per year
2–4 Mound Treatments
$100 to $300 through the season as needed
Total Annual Cost
$350 to $700 depending on property size and infestation pressure
Health & Safety Considerations
Human Allergies
About 1% of stung people experience severe allergic reactions, including anaphylaxis. Anyone in the household with prior insect sting reactions warrants proactive treatment.
Pet Risk
Dogs investigating mounds can receive dozens of stings. Reactions include swelling, infection, and in rare cases shock. Properties with outdoor dogs benefit from aggressive control.
If a Sting Happens
Wash with soap and water, apply a cold pack, and watch for severe reactions. Seek medical attention immediately for swelling beyond the sting site, breathing difficulty, or any allergic sign.
Special Property Considerations
High-Risk Locations
Properties next to undeveloped land, creek banks, or unmaintained neighbors face higher pressure and may need more frequent treatments. Fire ants re-invade constantly.
Timing Matters
Treat before May or June, when fire ants become most active, rather than reacting after a sting incident. Early spring treatment is especially important for families with kids or pets.
Mowing & Disturbance
Mowing over fire ant mounds disturbs but does not spread the colony. The queen, deep underground, is unaffected by surface disturbance. Mowing is fine — just watch the deck height.
