Beware the Bite: What You Need to Know About the Sneaky, Stinging Asian Needle Ant

Move over, Joro spiders and lanternflies—there’s another invasive pest making headlines this summer. The Asian needle ant, a small but potentially deadly insect, is spreading fast across the U.S., and experts are urging people—especially in the Southeast—to stay alert.

Originally detected in Georgia back in 1932, the Asian needle ant (scientifically known as Brachyponera chinensis) has mostly flown under the radar—until now. This tiny invader, native to parts of East Asia including China, Japan, and Korea, has now been spotted in over a dozen states, from Washington to Florida. It’s recently made appearances in Mississippi and Texas too.

So what’s the big deal? According to Dan Suiter, a professor of urban entomology at the University of Georgia, these ants pack a powerful sting. For most people, it’s painful. But for those with allergies to bee or ant stings, the venom can trigger anaphylaxis—a serious, potentially life-threatening allergic reaction. "If you suffer from anaphylaxis, you should really know what this ant looks like,” Suiter warns. “And it might be smart to carry an EpiPen.”

These ants are sneaky. Measuring less than a quarter-inch long, they’re easy to miss and like to nest in moist, hidden areas—think logs, rocks, or rotting wood. That makes wooded trails, backyards, and even mulch beds potential hiding spots.

How to Protect Yourself:

• Know what to look for. These ants are small, dark brown to black, with a sharp stinger.

• Avoid disturbing nests. They often hide in damp areas, especially during peak summer.

• Seek help with identification. You can send photos or samples to your local University of Georgia Extension office.

• Consider professional treatment. Baiting for these ants can prevent infestations before they get out of control.

Sadly, like many invasive species, the Asian needle ant appears to be here to stay. But with a little vigilance and education, we can stay one step ahead—and safe.
