Pavement Ants
Pavement ants are small, dark brown to black ants that typically nest in soil beneath pavement, sidewalks, driveways, and building foundations. They are easily identified by the parallel grooves on their heads and thorax visible under magnification. Colonies contain 3,000 to 5,000 workers with a single queen. They commonly push small piles of sand or soil up through cracks in pavement, creating the characteristic mounds that give them their name. They are a widespread nuisance pest from coast to coast.

Key Behaviors
Pavement ants are slow-moving, deliberate foragers that form well-organized trails to food sources. They feed on a wide variety of foods including grease, seeds, sweets, and dead insects. Adjacent colonies engage in dramatic territorial battles in spring and summer, producing swarms of fighting ants on sidewalks and driveways.
Risks & Concerns
Pavement ants are primarily a nuisance pest that contaminates food in kitchens and pantries. They do not cause structural damage but can be extremely persistent when they establish colonies beneath or within slab foundations. Their habit of pushing soil out from under pavers and foundations can undermine hardscaping over time.
Identification Tip
Distinguished from other small dark ants by the parallel striations on their head and thorax. Unlike odorous house ants, they do not produce a distinct smell when crushed and tend to nest in soil rather than wall voids.
