While the species is already too widespread and established for any hope of erradication, even simple population control is proving to be difficult. The animals are not attracted to the usual poison bait traps and so require specialized extermination. The colonies are polygyne (having multiple queens) and may even be interconnected into supercolonies, making colony destruction nearly impossible. Even when individuals are killed, the survivors will smartly pile their dead over the pesticide-treated areas to cross to safety. Via Texas A&M University
