Red imported fire ants will build their nest mounds outdoors in landscape areas or near a structural foundation. The ant will gain entry to a building through holes or cracks.


These ants will build large mound nests, and will sting humans who come across a nest.


Control / Prevention

Red imported fire ants and their tell tale mound nests should be actively avoided. To prevent entry into a structure, seal all internal and external cracks and crevices.


The sting of a red imported fire ant is painful and often results in a raised welt that becomes a white pustule. Often, a person stung by a red imported fire ant receives multiple painful stings from more than one of the ants. Persons allergic to insect stings will react more severely.
