Big-Headed Ant Infestation
Most indoor problems with bigheaded ants begin outdoors. As with most ants, the most common sign of a big headed ant infestation is the worker ants. They often are observed when foraging for food both inside and outside. Although they do not usually nest inside of homes, they often enter to forage through cracks in the foundation. Outdoors, these ants eat sweet liquids such as honeydew, dead insects, and soil invertebrates. Indoors, they prefer foods that are high in protein. These ants readily make trails between their nest and their food source. Colonies typically consist of multiple queens. Control of the big headed ant is difficult because the ant colonies are numerous and populations usually extend across property lines.
