Physical Characteristics
Little black ant workers are tiny, about 1/16 long, monomorphic, and dark brown to black in color – which differentiates them from the lighter-hued pharaoh ants and thief ants. Little black ant queens are double the size of the workers, about 1/8 inches in size. This ant has two nodes on its pedicel, but its sting is weak.

Behavior
Not much has been published on the little black ant. Its colonies, moderate to large in size, are common in Southern California, the San Francisco Bay Area and the Sacramento/San Joaquin Valley. Indoors, little black ant nests can be found in woodwork, decaying wood and masonry. Outdoors, nests will appear under stones and rocks, in rotting logs, in lawns and in open areas; these ants will forage in trails along foundation walls and on sidewalks. Alates (winged reproductives) appear from June to August. The little black ant will feed on grease, oil, meat, fruit, sweets and products made from vegetables such as corn, along with other insects, honeydew and plant secretions.
