Scientists Find Natural Way to Control Spread of Destructive Argentine Ants

Argentine ants attack a much larger harvester ant. In the United States, the invasive Argentine ants live in "super colonies" and generally cooperate with each other. But, altering the recognition cues on the exoskeletons of these ants could spark infighting among the residents of these vast colonies and help check their spread, according to research presented at the 232nd American Chemical Society National Meeting in San Francisco.
