Crazy Ants usually nest outdoors in mulch, wood, debris and soil; however, they can also nest indoors in dark voids. Colonies of crazy ants have many queens. The workers are small, dark brown ants that often run about erratically. They follow trails although their erratic behavior makes them difficult to follow back to the nest. Crazy ants can tend aphids, feed on honeydew, and are considered sweet-feeding ants.
