Its action is similar to that of Logic, but Logic isn't cleared for use on land producing food crops. Biological controls are a big element, but nobody is pretending that one organism will be the solution. Drees says existing chemical ant poisons are effective in urban areas. However, incorrect use has caused the EPA to cite 15 Texas communities for having surface runoff of diazinon. A network of biocontrols may hold the most promise on ag lands, parks, marshes and other vast places around the country-where these chemicals either can't be used legally or are too expensive.
Scientists hope other ants can then compete better against the weakened imported fire ants.
In Texas alone there are about 300 other species of ants, most native but some imported. On most of the 300 million acres in the U.S. where they live, red imported fire ants are a dominant scourge. They reign unhampered by natural enemies. In South America, their natural enemies make them just another ant. Click here .
