The Asian needle ant may look unassuming, but its sting can be more painful than that of a fire ant, posing a serious risk to those who have experienced anaphylaxis. This invasive species has been in the United States since the 1930s, likely arriving via ships transporting plants and livestock. While it is native to Japan, Korea, and China, the Asian needle ant has made a home in the Southeast and can be found as far north as Massachusetts.
University of Georgia entomologist Dan Suiter recently issued a warning about the dangers of this ant’s sting. Despite not being a new arrival, the ant has been causing concern as more people are reporting painful stings that have led to hospital visits. With summer in full swing, the chances of encountering this ant are higher, especially for those spending time outdoors.
One of the challenges with identifying the Asian needle ant is its nondescript appearance. Unlike other ants that leave pheromone trails, these ants do not follow a distinct path to food sources. Instead, they physically carry other workers to the food, making them harder to detect. They prefer nesting in damp wood, such as fallen logs or wet mulch, rather than building large nest mounds like fire ants.
If you come into contact with an Asian needle ant, it is essential to gently flick or brush it off to avoid being stung. The sting of these ants is not only initially more painful than that of a fire ant but can also be irritatingly persistent, causing discomfort that comes and goes. In their native range, Asian needle ant stings are associated with a higher risk of anaphylaxis compared to fire ants.
If you suspect you have Asian needle ants on your property, it is crucial to capture a specimen for identification. This information can be shared with your county agricultural agent for further analysis. For individuals with a history of allergic reactions to bee and ant stings, knowing how to identify this ant is vital. If you experience symptoms of anaphylaxis, such as hives, swelling, or difficulty breathing, seek immediate medical attention.
As awareness of the Asian needle ant grows, there is hope for more research and monitoring of its spread. By staying informed and taking precautions to avoid encounters with these ants, we can better protect ourselves and our communities from their painful stings.
