The Imported Fire Ant lives in mounds usually located outdoors on the ground surface. Sometimes colonies can be located in debris on the flat roof of commercial buildings. The ants have a well-developed stinger and can inflict a painful sting. Colonies of imported fire ants usually have one queen; however, multiple queen colonies have been found in many parts of Florida. Fire ants prefer to feed on oils, and fire ant baits are the best method of control.
