Crazy ants get their common name from the worker's 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.
Outdoors, the 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. These large ants are known to completely abandon one
nesting site and move to another. The colonies tend to be small,
composed of up to 2,000 workers, but larger colonies of more than
10,000 ants have also been found in debris piles and mulch
Crazy ants do not pose a health threat, but if they gain entry
to a structure, they can become a nuisance.
