Fire ants have long been a threat in the southern United States, but another aggressive ant species known as the tawny crazy ant is taking over in many areas of the region.

Unlike fire ants, crazy ants don’t sting, but they can become a nuisance once inside. They are highly adaptable, nest everywhere and are even known to damage electrical equipment, so it is important for homeowners to take steps to curb their activity.”

Crazy ants enter homes in the autumn or after rainfall because both conditions reduce their supply of honeydew. Once inside, crazy ants usually nest underneath floors or in wall voids. Outdoors, their nests are commonly found in soil under objects or next to foundations.

To prevent crazy ants from gaining access to a structure, we recommend the following tips:

  • Trim vegetation away from the home to prevent pathways inside.
  • Seal all cracks and crevices on the outside of the home, including around doors and windows.
  • Clean up food spills and other potential attractants as soon as possible.
  • If an infestation is suspected, contact a licensed pest professional to treat the problem.

Caribbean Crazy ants are golden-brown to reddish-brown in color, and are covered with dense hairs. After feeding, their abdomen will appear to be striped due to the stretching of the light colored membrane that connects the segments of the abdomen.


Range from 1/16-inch to 1/8-inch in length.


The Caribbean Crazy ant will scavenge for a wide variety of solid and liquid foods, such as seeds, fruits, garbage, honeydew, and practically any household food. They are also predatory and will attack other insects. Although they are called crazy ants, Caribbean Crazy ants actually follow very tight trails, which can be deceiving at first. Caribbean Crazy ants have rather large trails up to 3 or 4 inches in width and are very fast moving ants.


In the last few years, most of the reports of Caribbean Crazy ant infestations have come from pest control operators in and around South Florida. Trails consisting of thousands of Caribbean Crazy ants have been observed along sidewalks, buildings, and gardens.
