While some of the fire ants may be killed, completely eliminating the nest (which means killing the egg laying queen) is rarely accomplished with home methods. This allows the colony to rebuild and continue operating as usual. In fact it often increases the number of RIFA colonies.
Instant grits are a popular folk remedy for fire ants, but they are totally useless. Other methods, such as pouring gasoline or bleach into the mound are dangerous to people, pets and the environment. Even floods have not gotten rid of the pesky red imported fire ant. They just float away to another location.
The chart below, courtesy of the University of Arkansas Cooperative Extension Service, outlines various home remedies and their university-tested effectiveness in controlling home fire ant infestation.

What has been shown to be effective in controlling fire ants is Integrated Pest Management or IPM for short. The homeowner can attain about a year’s worth of control with an integrated pest management program based on either synthetic or organic chemical compounds formulated to reduce the red imported fire ant population. The latest research indicates a two step approach of a long acting and an immediate acting pesticide will produce the best results.
Presently, pesticide applications, organic and otherwise, are the only proven effective method for control. Many of us are leery of chemical intervention, generally with good reason, but the danger of leaving fire ants unmanaged far outweighs the danger from the pesticide applications necessary to eliminate the nests and queens.
