Size: 1/10 – 1/18 in.

    Color: Dark brown

    Body Structure: Head, abdomen and thorax with two spines on pedicel and stinger at end of thorax

    Characteristics: Generally slow-moving. New colonies are formed in the Spring when winged pavement ants, or “swarmers,” mate and reproduce.

    Habitat/Behavior: Colonies tend to nest near sidewalks or pavement, hence the name.  Presence of nests can be evidenced by soil mounds found between sidewalk cracks or near the edge of pavement.  They also can nest in hollow concrete block foundation walls or beneath concrete slab foundations.  Outdoors, pavement ants feed on honeydew and dead insects.  Indoors, they tend to seek out sugary or greasy items and can be detected by trails of worker ants searching for food.

    Commonly Active: Swarm in the late Spring and early Summer.

    Prevention/Treatment: Pavement ants tend to be drawn by fatty or sugary foods; so, keeping food preparation and dining areas free from food debris is a good step toward preventing infestation.  Although not particularly aggressive, pavement ants may bite and sting if provoked.  Also, locating pavement ant colonies is difficult, even though their mounds often are clearly visible on sidewalks and near home foundations. Therefore, it is recommended that a pest control professional inspect infested areas in order to locate and treat the true colony location.
