An invasive species of ants, with a potentially deadly sting, is spreading across the U.S. And that now includes Louisiana. That’s the word from LSU AgCenter Entomology Professor Aaron Ashbrook. As the Louisiana Radio Network reports, these Asian needle ants have been linked to severe allergic reactions, including intense pain, hives, redness and even anaphylaxis.
Ashbrook says unlike fire ants, Asian needle ants do not make mounds. They are small, dark brown to black, with light brown legs, and harbor a sting that feels like a needle, and is described as far more painful than that of a fire ant.
They tend to prefer moist shaded areas. So, Ashbrook suggests protecting yourself by wearing gloves, especially after a good rain storm. “You would typically encounter these ants if you were working with wet wood and wet soil. And there’s that potential for them to be aggravated and sting the individual.” Louisiana becomes at least the 22nd state where Asian needle ants have been detected. That also includes Arkansas and Texas.
The best way to eliminate Asian needle ants, according to Ashbrook, is to apply scatter baits in areas where you see them foraging. He says the ants will typically take the bait back to their nests to share with the colony.
