Question: How to control fire ant mounds

Answer: Fire ants can be difficult to control but you can try using baits. Fire ant baits consist of pesticides on processed corn grits coated with soybean oil. Worker ants take the bait back to the colony, where it is shared with the queen, which then either dies or becomes infertile. Baits currently available include Amdro, Siege, Logic, Award, Ascend, or Raid Fire Ant Killer. Baits are slow-acting and require weeks to months to achieve 80% to 90% control. Bait products can be used to easily treat large areas effectively. They contain extremely low amounts of toxins. For best results: Use fresh bait, preferably from an unopened container. Apply when the ground and grass are dry and no rain is expected for the next 24 to 48 hours. Apply when worker ants are actively looking for food, usually in late afternoon or in the evening.
