Pavement ants get their name because they make nests in or under cracks in pavement. These dark brown to black ants can also infest structures.
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.
These black pavement ants do not pose a public health risk, but they can contaminate food and should be avoided.
