Red Imported Fire Ants (Solenopsis invicta)
Red imported fire ants (RIFA) have been in the U.S. since the 1930s. RIFA are now found in the southeastern U.S., and parts of New Mexico, California, and Puerto Rico. This aggressive ant gets its name from its powerful sting, which causes a burning sensation. The stings may cause blisters and have been known to cause anaphylactic shock. These ants are a danger to humans, pets, and ground-nesting wildlife. RIFA can eat the seeds of certain crops and interfere with harvesting and cultivation operations. The ants also damage electrical equipment.
Dispersal of RIFA occurs during the mating process, as a result of floods, or by hitchhiking on vehicles, nursery stock, soil, sod, and grass.
