Various mechanical and electrical products have been marketed for fire ant control. One device was designed to electrocute fire ant workers as they climb onto an electric grid inserted into the mound or into a cone. These devices kill many worker ants, but the queens and brood are unaffected. There have been vibrating and sound-producing units designed to repel colonies, and devices that use microwaves or explosive elements to heat mounds or blow them up. Such products are often marketed without scientific evaluation. The fact that a “control” device is on the market does not indicate that it is effective. These products may kill some ants, but rarely eliminate a colony. Deceptive or fraudulent claims concerning fire ant control devices should be reported to the state’s attorney general or the Federal Trade Commission. |
