Females excavate nest close to shrubs for protection from burrowing ant-eating animals, spreading large mounds of waste earth. Sometimes nests are built in rotting logs or under stones. The mated queen tends 1st generation eggs and larvae, then 1st generation female workers take care of eggs, larvae, and queen.

Discussion:
Reports of devastating battalions of Fire Ants are well known in the South and Southwest. But although these ants often damage young plants, they rarely destroy established crops. Some people even consider this species a beneficial predator of insect pests. Other members of this common genus are found throughout North America but the range of individual species is more restricted.

WARNING: Stings from Fire Ants produce a painful, burning sensation.
