The Asian needle ant, an invasive species from Asia, is spreading across Georgia and the Southeast, raising concerns due to its painful sting, which can trigger severe allergic reactions, including anaphylaxis. Originally introduced to the U.S. in the 1930s, likely through potted plants, these ants have established colonies in states like Georgia, Alabama, North Carolina, and Tennessee, thriving in both urban and natural environments.
Unlike fire ants, Asian needle ants are less aggressive but deliver a sting that can cause intense pain, swelling, and, in rare cases, life-threatening anaphylaxis. A 2025 study from the University of Georgia, published in Annals of Allergy, Asthma & Immunology, found that 7% of Georgians stung by these ants developed moderate to severe allergic reactions, with some requiring emergency treatment. The study suggests the ant’s venom may contain unique proteins that heighten allergic responses, though further research is needed.
These ants, identifiable by their dark brown to black bodies and pale legs, nest in diverse locations like leaf litter, under rocks, or near building foundations, making them hard to avoid. They are particularly active in shaded, moist areas and can displace native ant species, disrupting local ecosystems. Experts recommend increased awareness, especially for outdoor workers, and advise those with known insect sting allergies to carry epinephrine auto-injectors.
Efforts to control the Asian needle ant include targeted pesticide applications and public education on identifying and avoiding nests. As the species continues to spread, researchers are studying its ecological impact and potential medical risks to better manage this growing threat in the Southeast.
