Little black ant swarms are common from June to August, during which time they forage in trails and are frequently seen along sidewalks.
These small ants feed on grease, oil, meats, fruits, and vegetables materials such as corn meal and sweets. The workers also feed on other insects, honeydew and plant secretions.
Little black ants are common in wooded areas. In yards, they nest under rocks, in rotting logs, and under piles of bricks or lumber. Indoors, nests are located in woodwork, wall voids, decaying wood, masonry, and behind facades.
Although little black ants have a stinger, it is often too small and weak to be effective.
