Inside a building, pavement ants will occasionally nest in walls, in insulation, and under floors. The most likely place is in the building foundation and especially near some heat source. They often follow pipes which come through slabs for access to upper floors of buildings.
Outside, these ants typically nest under stones, in cracks in pavement, and next to buildings. They enter buildings through cracks in the slab and walls, slab expansion joints, and the natural openings of buildings. Although not aggressive, workers can bite and sting.
These ants feed on almost anything including insects, honeydew, seeds, plant sap, and household foods such as meats, nuts, cheese, honey, and bread, but show a preference for meats and grease. They forage in trails, and for distances of up to 30 feet (9 m).
