Red imported fire ants nest in soil and build mound nests. They can infest garages.
These ants will build large mound nests, and will sting humans who come across a nest.
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.
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.
