Fire Ants in Alabama: Why They Get Worse Every Summer, and How to Actually Kill Them
Spot treatment doesn't work. Mound drenching barely works. Here's what does — and why fire ants love Alabama more than almost anywhere in the U.S.
Fire ants did not exist in Alabama before 1940. They came up from South America through the Port of Mobile, and within 80 years they've colonized every county in the state. There are now more fire ants per acre in Alabama than there are people in the country.
Most people fight them wrong. Let me explain.
Why spot treatment fails
When you see a fire ant mound and pour boiling water on it, or hit it with grits, or dump granular insecticide on top — you're killing the surface workers. The queen is two feet below the surface. She doesn't die, and she doesn't even slow down egg production. Worse: if she senses a threat, she relocates the colony 8 to 30 feet away within 24 hours. You'll see a new mound next week.
This is why fire ant mounds seem to "follow you" around the yard.
Why yard-wide bait treatment works
The right approach is to treat the entire yard with a bait that the workers carry back to the queen voluntarily. The bait must:
- Be slow-acting (workers must survive long enough to share with the queen).
- Be attractive to fire ants specifically — not a generic ant bait that gets ignored.
- Be applied during the active foraging window — 70°F to 90°F, with no rain in the next 24 hours.
We use a granular bait product applied across the whole yard, typically at 1 to 1.5 pounds per acre. Workers find it within 30 minutes, harvest it, take it underground, and the colony collapses over 4 to 8 weeks. Treated yards stay clear for 12 to 18 months.
Why lake homes are worse
Lake Martin, Smith Lake, Wheeler Lake, Logan Martin — every reservoir in Alabama has heavy fire ant pressure on the surrounding lots. Two reasons. First, fire ants thrive in disturbed soil — and lakefront construction disturbs a lot of soil. Second, mound flooding during high-water periods causes rafting — entire colonies clump into living balls and float to dry ground. Those rafts wash up on your lot, dry out, and become new mounds.
If you have a lake home and kids who go barefoot, fire ant control is not optional. A single sting won't kill anyone (unless they have a severe allergy), but 50 stings on a 4-year-old's foot is a trip to the emergency room.
When to schedule treatment
April to October. The two best windows are early May (before peak summer mound activity) and late August (catches the second-wave colonies). One treatment usually gets a yard, but heavily infested lots may need a follow-up at 60 days.

Fire ant control is an add-on to our pest control program, or a one-time service if that's all you need. Bundles with our outdoor program (mosquito + tick + flea) for the most complete summer protection.
