GRIFFIN, Ga. (AP) — University of Georgia officials say an invasive ant species native to South America has been found living in Georgia.

UGA Extension agent James Morgan says he found the ants Aug. 15 at an assisted living facility after its director called looking for help.

Morgan says the ants differ in color from fire ants and other types commonly found in Georgia and they behave differently as well. Morgan says the ants move erratically and don't march in straight rows.

Morgan sent a sample of the ants to an entomologist, who confirmed the insects are Nylanderia fulva — commonly known as tawny crazy ants.

Officials say the ants are considered a nuisance because they're attracted to electricity and travel in masses.

Researchers are unsure of how the ants got to Georgia.
