The USDA is warning people to be on the lookout for invasive ants that have been reported in 17 states, including Texas.
HOUSTON —
Experts are sounding the alarm about the invasive Asian needle ant. They’ve been reported in 17 states and their sting packs a punch, the USDA warns.
It contains venom that causes potentially deadly allergic reactions called anaphylaxis. Symptoms include low blood pressure, difficulty breathing, and swelling of the tongue and throat. If you suspect someone is having a systemic allergic reaction to an ant sting, seek medical attention immediately.
Their sting can also inflict serious pain, lasting for several hours. The pain may occur at the location of the sting or away from the sting, causing redness of the skin and hives.
Experts say the Asian needle ants are a threat to native ant species that are critical to the ecosystem.
The Asian needle (Brachyponera chinensis) is native to China, Japan, and Korea.
They invaded the Southeastern United States in 1932 and have now been reported in 17 states, including Texas.
How to spot an Asian needle ant
A small but mighty creature only .2 inches long, they’re not easily identifiable, according to the USDA. They’re shiny with a dark brown to black head and torso and lighter orange-brown antennae and legs and resemble other species.
The ants may find shelter in forest areas, near homes and businesses, under mulch, pavers or landscape timbers, the USDA reports. To be safe from the ants, take care around potential nesting areas such as rocks, logs, rotting wood, and leaf litter.
Within the last 20 years, researchers have tried to control species by treating remote forest areas.
