A Technical Report from The Bartlett Tree Research Laboratories
The Red Imported Fire Ant (RIFA) was accidentally introduced into the United States from Brazil in the 1930s and they now infest 13 southern and western states. These ants reproduce rapidly and build mounds in almost any type of soil but prefer open sunny areas such as pastures, parks, golf courses, and home lawns. They will also build mounds in mulch and compost piles, rotting logs and even under buildings. Fire ants can sting repeatedly and stings are painful and can become infected. Fire ant stings can be lethal to hypersensitive individuals.
