Fire Ants in Ellis County: Your Friendly Guide to a Calmer Yard
If you have lived in Waxahachie, Red Oak, or anywhere in Ellis County for long, you have met red imported fire ants. They are part of life in Texas yards, but with a little timing and patience you can keep them in check. Here are straight answers to the questions folks ask most, drawn from Texas A&M AgriLife's fire ant experts.
How do I eliminate fire ants from my yard?
There is no single, easy answer for every yard. Texas A&M says most people with more than a handful of mounds (about 5 per quarter-acre yard) are happy with a bait or the "Two-Step Method," which can reduce mounds by 80 to 90% in the treated area. No method works 100% of the time, and none is permanent. New colonies usually show up after the next rain, and certainly within a year.
What is the "Two-Step Method"?
It is a proven approach for heavily infested lawns:
Broadcast a fire ant bait over the yard once or twice a year.
Between those broadcasts, treat individual nuisance mounds as needed with a mound treatment (or very hot water as a drench).
Texas A&M notes this approach is more cost-effective and environmentally friendly than most other chemical approaches, and "organic" product options are available.
Why tackle fire ants in the fall?
Late August through October is an ideal time to put out bait. Many baits work slowly, so a fall application keeps working over the winter and mound numbers are already down by early spring. Baiting too early in spring, when it is below 65°F, does not work well because the ants are not out foraging.
It's been dry and I don't see any fire ants. Are they still around?
Yes. In hot, dry spells the ants simply stop building mounds and nest deeper, coming out to forage in the cooler parts of the day or at night. That is also when they are more likely to wander indoors looking for food and water. Baiting can work well in these conditions; Texas A&M suggests putting it out in the late afternoon or evening.
Which bait should I use, and how long does it take to work?
Texas A&M AgriLife does not endorse specific brands, but it explains how the active ingredients differ. Some baits reach maximum control in about 2 weeks, others in 3 to 6 weeks, and insect growth regulator baits can take several months but suppress colonies longer. The key is patience. Whatever you choose, read and follow the label.
A helpful tip: bait works best between 65 and 95°F, when ants are foraging. Set out a potato chip; if ants cover it within 45 to 60 minutes, it is a good time to bait. Texas A&M also advises baiting when no rain is expected for the next 8 to 24 hours.
Can my whole neighborhood or HOA treat together?
Yes, and it often works better. The Two-Step Method works best over larger areas like city blocks, neighborhoods, HOAs, school grounds, and parks, and larger treated areas see fewer ants moving back in from untreated property next door. AgriLife runs a community fire ant management program to help groups do just that.
What should I do if I get stung?
Most stings leave an itchy white pustule. Keep the area clean and avoid breaking it open to prevent infection. Watch for warning signs of a serious allergic reaction, such as trouble breathing, swelling of the lips, face, or throat, dizziness, or hives. If any of those show up, call 911 right away. For questions about a sting, call your doctor or the Texas Poison Center at 1-800-222-1222 (free and open 24/7). This is general information, not medical advice.
