About 1/8-inch long.
Pavement ants are identifiable by the grooves on the head and thorax.
Individual pavement colonies can often be controlled using ant baits, but perimeter inspection and treatment are commonly necessary for long-term relief.
This ant’s name is derived from its preference for nesting in soil next to and beneath slabs, sidewalks, patios, and driveways. Colonies are usually easy to find due to the piles of displaced soil next to and on top of pavement. Indoors, pavement ants nest under the foundation and within hollow block foundation walls. Occasionally, a colony may carry soil up into a wall to form a nest. When piles of soil appear from under baseboards or on top of a basement or garage floor, it is a good sign that pavement ants may be present.
Individual pavement colonies can often be controlled using ant baits, but perimeter inspection and treatment are commonly necessary for long-term relief. Pavement ant colonies are controlled by direct treatment of nests in the soil. Where colonies are located under slabs, ant baits may be successful in controlling an infestation. If baits are unsuccessful, the slab may need to be drilled and treated underneath.
