Big-headed Ant Behavior
Most indoor problems with big-headed ants begin outdoors. 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.
With Halloween just around the corner, its time for larger-than-life creepy, crawly creatures skittering across lawns, lurking in dark alleyways and dropping out of nowhere to frighten their hapless victims.
