Characteristics

  • Size: One-eighth of an inch long, with extremely long legs and antennae.
  • Color: Black.
  • Behavior: Crazy ants may develop huge colonies containing thousands of workers and numerous queens.

Habitats

Crazy ants are common in all the Gulf Coast states from Florida to Texas and can be found in parts of Arizona and in commercial buildings in a few northern cities, such as Philadelphia and New York. These ants nest outdoors under items on the ground, within landscape mulch, beneath loose bark on trees, under ground cover, in potted plants and within piles of items such as lumber, firewood or bricks. Nests may readily be established inside homes in walls, beneath carpeting and in other suitable voids or spaces.

 

Tips for Control

This species may be difficult to control and does not feed much on ant baits. The keys to control are to find the colonies and subcolonies and treat them directly. Regular inspections and service are necessary to find and treat new colonies as they move from neighboring properties. The services of a professional, such as Terminix, are very helpful when encountering these ants. General tips for limiting ant infestations include:
  • Eliminating piles of lumber, bricks or other debris that could serve as a nesting site for ants.
  • Keeping landscape mulch less than two inches thick and at least 12 inches away from foundations.
  • Ensuring the sprinkler system does not spray directly onto the foundation.
  • Sealing as many cracks in the home's exterior as possible.
  • Keeping tree and shrub branches trimmed to prevent touching the home.
  • Considering re-landscaping to avoid using plants that are prone to aphids and similar insects. At the very least, treat such plants for aphids regularly. A tree/shrub company can be helpful with this task.
