Crazy ants get their common name from the workers' habit of running in an erratic, jerky manner when searching for food.
Crazy ants feed primarily on live and dead insects, seeds, fruits and honeydew. They enter homes in the autumn or after rainfall because both conditions reduce their supply of honeydew. Inside, crazy ants usually nest underneath floors or carpeting, in potted plants and in wall voids. Outdoors, their nests are shallow and commonly found in soil under objects or next to foundations. Crazy ants are highly adaptable, nesting in both dry and moist habitats.
Crazy ants do not pose a health threat, but if they gain entry to a structure they can become a nuisance.
