Fire ants from Brazil now infest the southern United States  Unlike queen fire ants in Brazil, two queens in the United States share a nest  Ants from these nests are more aggressive than those from single-queen nests  By destroying virtually all insects in the nest area, these aggressive ants gain sole access to food sources, and the ant population skyrockets
Since certain predator insects in Brazil limit the fire-ant population there, importing such predator insects into the United States would be of overall benefit to the environment by stopping the increase of the fire-ant population in the United States
The predator insects from Brazil could survive in the ecological environment found in the United States.
