Red Imported Fire Ants

Native to central South America, red imported fire ants are established in the U.S. and Australia. Its sting is 95% alkaloid venom, which causes both the pain and white pustule that appears about a day after the sting occurs. In urban settings, they may nest under patio slabs, in lawns, under edges of sidewalks, foundations, concrete driveways, and electrical boxes. After a heavy rain, the colony may move to higher ground or inside homes to take refuge from saturated soil. They also reduce ground-nesting populations of rodents and birds.
