Tawny Crazy Ant Spreading Across Gulf States

From the School IPM 2015 Newsletter

An invasive ant species is growing in numbers and range in Gulf Coast states. Formerly known as the raspberry crazy ant, the tawny crazy ant, Nylanderia fulva, was first spotted in Texas in 2002. Named for their random, nonlinear movement when looking for food, the crazy ant is sometimes found in electrical equipment and household appliances. Studies have shown that the tawny crazy ant is able to sheath itself in protective acid that allows them outcompete fire ants and other ant species, moving them up to the number one pest concern where they are present.

This pest is the tawny crazy ant, Nylanderia fulva (also known as the Caribbean crazy ant, hairy crazy ant, and Rasberry crazy ant). It is difficult to explain to those that have not witnessed an infestation firsthand just how dense the populations of crazy ants can be. Under every stone, foraging up every tree, and crawling over every blade of grass, the tawny crazy ant is ubiquitous throughout the landscape in neighborhoods from Florida to Texas. It is not an exaggeration to describe their populations as biblical plague-like proportions.
