What are pavement ants?
Adult pavement ants can fluctuate in color from dark brown to black, the head and thorax have grooved parallel lines, and the thorax has a pair of small spines extending out from the rear end. The reproductive members of the colony are winged and are slightly bigger than the workers. Queens grow to be about 3/8th of an inch in length; workers are smaller, growing to about 1/8 of an inch in length.
Why do I have them?
Pavement ants usually spend their life living outside nesting in and along sidewalks, underneath foundations, under concrete slabs, and along stone walls. Pavement ants most often invade homes while foraging for food; they have a varied diet and will feast on sweets, fruits, seeds, cheese, grease, and dead insects. Pavement ants can become a particular problem in homes and buildings that have stone foundations or dirt basements.
