The black carpenter ant invade homes in search of food. These ants excavate moist, rotting wood and other soft materials to make satellite nests. The presence of large, wingless or winged ants inside a home is usually the first sign of an infestation. This does not necessarily mean that a nest is present indoors. The nest may actually be located outside, near the building. Foraging workers from the nest enter the structure in search of food and water. These worker ants will feed any food left out.
