Pavement Ants in Bristol

Pavement ants are incredibly small, only ranging from 2.5–4 mm. Varying between black and dark brown colors, these tiny ants can become a big nuisance. They are very common in urban environments. One of the biggest attractants of pavement ants is pet food that has been left out or not properly sealed. When these ants get inside your home, they can be extremely difficult to get rid of. Swarms from mature pavement ant colonies occur in the spring but may occur continuously if the nest is located indoors. 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.

Pavement Ant Habitat

Pavement ants move in slow deliberate motion and trails are often seen at night going to and from food sources. True to their name, pavement ants nest under or near sidewalks, slabs, and concrete, making urban habitats ideal due to the lack of vegetation. When building nests, they place any soil removed in a mound near their nesting site. These mounds are usually discovered 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.

Pavement Ant Behaviors & Dangers

Although pavement ants have the ability to bite or sting, they rarely do so. 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.
