How Caribbean Crazy Ants Came To Florida

May 22, 2018

Are you noticing numbers of smooth, glossy, golden-brown or reddish-brown ants in or around your home? Do they move quickly and erratically? These are called Caribbean crazy ants and they are relatively new to Florida. Although they do not bite or sting, they can be disturbing since they tend to travel in groups numbering in the thousands. The fact is, unlike many other types of ants, Caribbean crazy ants have multiple queens so populations grow quickly. They are known to "blanket" over yards and sidewalks and even lodge in the nostrils of animals, thus asphyxiating newborn livestock. Because of their rapid growth and multiple queens, DIY methods of control have limited amounts of success at best.

These ants were first sighted in Miami and Coral Gables in 1953, but they have wasted no time spreading. Researchers believe that this pest ant first entered Florida via cargo in the Port of Miami and the Port of St. Lucie where the first infestations were found. These ants are likely to be seen traveling in large numbers along sidewalks, in shrubs, and around the foundations of buildings.

Problems Caribbean Crazy Ants Cause

  • They reproduce quickly and invade in very large numbers.

  • They are not only a nuisance but they will attack humans or pets if provoked.

  • They have no problem invading homes.

  • They have a tendency to get into electronics, which can cause shortages in electrical circuits.

  • They are frustrating to clean up since they invade in such large numbers.

  • They will contaminate food sources if they make their way into kitchen or pantry areas. These ants invade in such large numbers, they can completely cover food in no time at all. Not only is this disturbing to witness, it can become quite costly if the infestation is not taken care of promptly and effectively.


  • Seal up entry points. Examine the outside of your foundation and outer walls for gaps, cracks, and holes, paying close attention to areas around pipes, wires and other items that enter the home. Seal up any holes you find. Keep in mind that it doesn't take much of a hole for an ant to squeeze through.

  • Eliminate smells. Be sure all trash is stored in containers with tight-fitting lids, and don't leave food sources outside to lure pests in close.

  • In your home, store foods in the fridge, freezer, or in sturdy containers with sealable lids. Clean your home regularly, removing food spills, crumbs, and other food sources.

  • Keep things dry. All pests need a water source.

  • Partner with a trusted, professional pest control company.
