(AP Photo/Manuel Balce Ceneta, File)AP Photo/Manuel Balce CenetaMillions of tiny invasive ants are spreading across parts of the South, and they can create a much bigger problem than an unwanted trail through the kitchen. Tawny crazy ants can form huge populations, invade homes and damage electrical equipment, according to the U.S. Department of Agriculture. The reddish-brown insects are native to South America and have become established mainly in Texas and Florida, along with coastal areas of Louisiana, Mississippi, Alabama and Georgia. The ants get their unusual name from their quick and unpredictable movements. They can also live in enormous groups known as supercolonies. Texas Invasives says some colonies can contain millions of young ants, while large infestations can push out other ant species and affect wildlife. Texas Invasives says their massive numbers can cover the ground and trees in heavily infested areas. For homeowners, one of their most troubling habits happens indoors. The ants can get into electrical equipment and cause expensive damage. Texas A&M AgriLife Extension says tawny crazy ants can damage or destroy electrical components and nest in and around structures. Unlike fire ants, however, tawny crazy ants do not build noticeable mounds. Stopping their spread can be difficult because people may unknowingly move them. Plants, mulch, construction materials, yard debris and hay have all helped transport the ants to new locations, according to Texas A&M researchers. Once introduced, populations can reach extraordinary levels within a year or two. Experts say recognizing the ant is an important first step. Workers are small, hairy and reddish-brown, with long legs and antennae. Large infestations can be difficult and costly to control, making early identification particularly important as the invasive ants continue expanding their territory. Texas A&M recommends preventing their spread into new areas.
