These black ants will eat almost anything. Pavement ants have been known to consume insects, seeds, honeydew, honey, bread, meats, nuts and cheese. They forage in trails for distances of up to 30 feet and are known to climb masonry walls that enter into occupied areas.
In buildings, pavement ants are most likely to be found in ground-level masonry walls, but they also nest in walls, insulation and under floors. Outside, these black ants typically nest under stones, pavement cracks and next to buildings.
