Invasive Asian Needle Ants Spread Across the U.S. with Potentially Lethal Stings The U.S. is facing a growing threat from invasive Asian needle ants, which have spread rapidly across the country and are causing significant ecological disruption. These ants, known for their potent venom and ability to deliver a painful sting, have become a major concern for scientists and residents alike. Experts warn that their expansion is not only affecting natural ecosystems but also posing risks to human health, particularly for those with allergies to insect stings. Asian needle ants, native to Asia, have been identified in multiple states, including Washington, Wisconsin, and others along the West Coast and Midwest. According to AntMaps, their range is likely larger than currently documented, as the ants are adept at remaining undetected. Emilee Poole, an entomologist with the U.S. Forest Service, noted that the ants have infiltrated heavily invaded forests in Georgia, where they now occupy nearly every stump, log, or branch on the forest floor. This widespread presence has led to a dramatic shift in local ecosystems, with native ant populations declining in areas where the invasive species have established themselves. The ants’ venom is particularly concerning. While the sting is described as a throbbing, stinging sensation that can last over 30 minutes, it may trigger severe allergic reactions in some individuals. Poole reported that the sting site becomes red, itchy, and mildly swollen, but the effects can persist or recur later in the day. For those with known allergies, the risk is even higher, as the venom is more likely to cause anaphylaxis compared to the sting of a honey bee.#north_carolina_state_university #us_forest_service #asian_needle_ants #emilee_poole #antmaps
