Pavement ants get their name from commonly locating their nests in or under cracks in pavement. Workers are about 1/16 – 1/8” long and light brown to black in color. Inside, pavement ants are most likely found in ground-level masonry walls of the foundation and favor areas by heat sources in winter. Outside, they typically nest in cracks in pavement, walkways, under patios and commonly seek entry via cracks in foundations, slabs, slab expansion joints and natural openings. Pavement ants swarm primarily in June and July, but also have the potential to swarm during winter months especially in heated structures.
