Pavement ants are small, dark brown to black, and 2.5 to 3 mm in length. They look like a small carpenter ant with red legs.
Nesting sites include beside and under sidewalks, patio blocks, building foundations, driveways, and in landscaping beds. They frequently kick out visible sand and debris from these locations.
Mounds of displaced soil are often observed in areas of their nests. Once inside a building, they can travel along pipes and electrical wires as well as under the edges of carpets.
