Pavement Ants in Iowa
Pavement ants build nests beside and under sidewalks, driveways, and foundations. These ants earned their name due to their tendency to burrow under concrete, pavement, or asphalt surfaces and construct nests. Pavement ants will pile the dirt removed from constructing nests in mounds on top of the pavement. They feed on meat, grease, dead insects, and sweets, however, their favorite food is the honeydew produced by aphids and mealybugs. Swarms occur in the spring and ant swarmers are sometimes confused with termites. Since they build their nests in close proximity to homes, they often make their way indoors in search of food.
Pavement Ant Habitat
True to their name, pavement ants nest under or near sidewalks, slabs, and concrete, making urban habitats ideal due to the lack of vegetation. Moving in slow deliberate motion, pavement ants can be found trailing at night going to and from food sources. When building nests, pavement ants place any soil removed in a mound near their nesting site. Mounds are usually noticed on the surface of the ground or next to a patio or sidewalk. Inside homes, ants tend to be found in kitchen areas or the patio, establishing nests inside wall voids, insulation, or under flooring.
