Pavement Ants in SE Louisiana and Mississippi

The pavement ant received its name from its habit of nesting alongside and under sidewalks, driveways, and foundation. Pavement ants pile the dirt removed from the nest in a mound on top of the pavement. As household pests, pavement ants are attracted to both greasy and sweet foods. Due to their close proximity to homes and buildings, these ants often make their way indoors in search of food. They can cause a severe problem when a structure is built on a slab.

Pavement Ant Habitat

True to their name, pavement ants are most often found under or near sidewalks, patios, and driveways. Nests are located in the soil in the open or under stones and pavement, masonry or wood. Nests generally occur at ground level and workers use pipes or wires to move upward. In commercial buildings, they often become an issue when the alates or reproductives emerge from openings in walls above false ceilings then drop into the rooms below. Although they prefer to be outdoors in warm weather, during winter, they are more likely to invade homes. Any heat source, such as a radiator or heating duct, can make a suitable nesting site for pavement ants.

Pavement Ants Behaviors, Threats and Dangers

Nuisance pests, pavement ants cause unsightly piles of sand on driveways, patios, sidewalks, or in basements. Although they can bite and they do have a stinger, pavement ants rarely bite humans. These ants do not pose a public health risk, but they can contaminate food as they forage. They will scavenge for any kind of edible crumb, invading homes in large numbers. When nests are not treated in time, pavement ants will continue to spread into new populations. If you suspect a pavement ant problem, contact a licensed ant exterminator.
