Pavement Ants in Nevada

The pavement ant gets its name from its habit of nesting beside and under sidewalks, driveways, and foundation. They are particularly common in the Las Vegas valley and new colonies are established after mating flights in June and July. Ant swarmers are sometimes confused with termites and cause unsightly issues when swarming in commercial buildings. Since they build their nests in pavement, walkways, and sidewalks next to structures, they often make their way indoors in search of food. These ants are a nuisance, piling the dirt removed from building their nest into a mound on top of the pavement. Due to their close proximity to homes and buildings, these ants often make their way indoors in search of food. 

Pavement Ant Habitat

Pavement ants are most often found under or near sidewalks, patios, and driveways. Located in the soil in the open or under stones and pavement, masonry or wood, nests generally occur at ground level.  Workers in pavement ant colonies use pipes or wires to move upward. In commercial buildings, pavement ants can become an issue. Sometimes, alates or reproductives emerge from openings in walls above false ceilings and then drop into the rooms below. Preferring to be outdoors in warm weather, during winter, pavement ants are more likely to be found in homes near a heat source such as heating duct. 

Pavement Ant Behaviors, Threats or Dangers

Pavement ants are nuisance pests, causing 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. Considered a nuisance pest, pavement ants create unattractive piles of debris on driveways, sidewalks, and inside commercial buildings. Pavement ants contaminate food as they invade homes in large numbers. When nests aren’t treated in time, pavement ants will continue to spread throughout a home or business as they form new colonies. If you suspect a pavement ant infestation, consult a professional ant exterminator.
