Fire ant mounds appear in residential yards, commercial properties, and public areas including schools, playgrounds and parks. These insects cause painful stings and can trigger severe allergic reactions in some people. University of Tennessee Extension provides advice for safe control during summer.
Urban entomology specialist Karen Vail states that sting-related anaphylaxis can be fatal, so effective management helps protect communities. Homeowners with fewer than 20 mounds per acre can use single-mound bait treatments. Fresh baits from garden stores should be measured and scattered around each mound, not on top, when temperatures range from 70 to 85°F, ideally in the evening.
Bait works best when ants are actively foraging. A test with oily food such as hot dog bits or chips next to a small bait portion can confirm activity after 30 minutes. Avoid applications after mowing or when rain or heavy dew is forecast, as these reduce results.
For properties exceeding 20 mounds per acre, a broadcaster spreads bait across larger zones. Unsafe home methods like boiling water or flammables are not advised. Products must follow label rules, and baits should be stored sealed at room temperature away from other chemicals. Retreatment with alternative methods may be needed if activity continues.
