Another invasive species is slowly crawling its way across the United States. Over the past few decades, the Asian needle ants have spread to more than 20 states since their first appearance in Georgia and North Carolina in 1932, according to the U.S. Forest Service. They originate from the temperate regions of East Asia.

Experts are concerned about the insects spreading throughout the nation since they are venomous and can cause serious allergic reactions with their painful sting. In 2024, at least three cases of life-threatening anaphylactic reactions were reported in Georgia, making this little (and little-known) insect a growing problem.

Even though it's not often aggressive, the ant's sting can pierce clothing and cause severe, persistent pain, according to the U.S. Forest Service. It's sting can cause anaphylaxis, a potentially life-threatening allergic reaction causing a rapid heartbeat, breathing issues and swelling in the throat.

Here's what you should know about invading ants and how to keep your family safe.

There have been reports of the invasive Asian needle ants in more than 20 states in the United States, mostly in the Southeast and certain regions of the Mid-Atlantic.
