South Carolina residents are advised to be aware of the Asian Needle Ant, an invasive species whose sightings are reportedly increasing across at least 17 states, including Georgia and South Carolina. This ant, present in the U.S. since the 1930s, is now recognized as a “medical pest” due to its potent sting.
While resembling a common ant, the Asian Needle Ant possesses a distinguishing characteristic: its sting can induce anaphylaxis in some individuals, a potentially life-threatening allergic reaction. Experts have noted numerous cases of people experiencing severe allergic responses requiring hospitalization after being stung by this species.
These ants primarily inhabit hardwood environments, making areas with logs and firewood potential nesting sites. To minimize encounters, it is recommended to keep firewood elevated off the ground, preventing ants from moving into the wood and being carried indoors. When gardening or handling items that have been left on the ground for several days, individuals should inspect underneath them and brush off any visible ants.
If residents suspect they have Asian Needle Ants in their yards, they are encouraged to collect a few specimens in a jar. These samples can then be sent to local extension coordinators for proper identification by entomologists.
