As poisonous Asian needle ants spread throughout more areas of the United States, officials are raising the alarm.
These insects are indigenous to China, and their sting can cause fatal allergic reactions.
Although this invasive species was initially identified in the US over 90 years ago, its population has recently increased to at least 20 US states.
Florida, Georgia, Alabama, Mississippi, Arkansas, Tennessee, the Carolinas, Kentucky, Virginia, Ohio, Pennsylvania, Maryland, Connecticut, Rhode Island, Massachusetts, New York, Wisconsin, Washington State, and Texas are among them.
Workers and queens of the Asian needle ant can grow up to one-fifth of an inch in length, making them small to medium-sized ants. They are glossy, dark brown to black, with brighter orange-brown legs and antennal tips.
According to the US Department of Agriculture (USDA), their stings cause “intense pain” at the site that “comes and goes over the course of several hours,” but some persons have also reported pain away from the sting site.
An Asian needle ant sting may also cause anaphylaxis, a potentially fatal allergic reaction.
Although they have been found in parks, lawns, potted plants, under wood piles and lurking in building materials like logs, bricks and pavers, these ants prefer moist places behind stones or decaying logs.

According to Scott Egan, an associate professor of biosciences at Rice University, the ant was recently discovered in Texas. He told Click2Houston, “It’s important to be aware of this new invader, but we need to learn more.”Some people may experience an allergic reaction, including anaphylaxis, and it is said to be painful. A medical or veterinary professional should handle that.
Egan advises locals to remain vigilant and record any odd ant activity, even though sightings in Texas are still very rare.
“People have been dealing with this species for nearly a century in places like North Carolina,” he stated. “We’re just beginning to understand how it fits into our local ecosystems here in Texas.”
Although this species isn’t known to be hostile, when it feels threatened, it will sting to protect itself. Their stingers have the ability to puncture clothes and get to the skin.
“The good news is, they’re not terribly aggressive like the fire ant, so we don’t have quite the health concern, but I understand they do enact a very painful sting if people do interact with them,” Bedford extension agent Scott Baker of the Virginia Cooperative Extension told ABC 13 News. Although the ants are not as dangerous as some other species, people should still exercise caution.
The “swarming” season, which usually starts in spring and lasts until August and is when insects emerge from hibernation to begin mating, is when Asian needle ants are most likely to occur inside homes.
Although some people have reported experiencing pain away from the sting location, their stings create “intense pain” at the site that “comes and goes over the course of several hours.”
Because of its great adaptability, this species may flourish in both urban and rural settings and in both warm and chilly temperatures.
Scientists predict that the Asian needle ant will continue to proliferate in the United States, where it has established a sizable population.
Both the environment and human health are at risk from this.
In regions where Asian needle ants are established, studies have revealed that this invasive species is displacing native ant species, leading to a decrease in their diversity and abundance.
Some of these indigenous ant species are essential seed dispersers, ensuring that the plant species is properly dispersed by transporting seeds away from their mother plant.
According to the USDA, “researchers have shown significant reductions in seed dispersal where Asian needle ants have invaded forest areas, so this invasive species could have dramatic, long-term negative effects on the forest understory.”
Scientists are researching and creating methods to manage this enormous ant population.
However, the USDA said that “unfortunately, as with many invasive species, it appears Asian needle ants are here to stay.”
