A pavement ant, scientifically known as Tetramorium caespitum, is a species of ant commonly found in urban areas throughout North America. This small, brownish-black colored ant is characterized by its strong affinity for nesting under and around pavements, sidewalks, and driveways, hence its name.
Pavement ants typically measure around 1/8 inch in size, with workers being slightly larger than the colony's numerous winged reproductive ants. They possess an unmistakable appearance, featuring segmented bodies, six legs, and a pair of distinctive antennae that aid in sensing their environment. These ants can easily adapt to a wide range of climates, making them highly successful and resilient urban dwellers.
Pavement ants construct complex underground nests that consist of interconnected galleries and chambers. They use soil particles, small stones, and organic matter to create these intricate structures, which can extend as deep as several feet below the surface. Despite primarily dwelling beneath concrete structures, pavement ants commonly venture into buildings in search of food. Their diet primarily consists of sweet substances, insects, seeds, and other organic matter.
Considered a nuisance pest, pavement ants can establish large colonies and become a bother to homeowners and businesses alike. They often form visible trails, which consist of worker ants traveling to and from their food sources. As a result, their presence can lead to contamination of food and discomfort in residential areas.
To manage and control pavement ant infestations, various methods can be adopted, including sanitation practices, sealing entry points, and regular removing of food scraps. Additionally, targeted use of ant baits and insecticides can effectively help reduce their population.
