The workers of this species measure about 1/8-inch in length. Colonies contain multiple queens who are 2 to 3 times larger than the workers and are black in color.
Little black ants are usually seen around homes following well-defined trails between the nest and food and water sources and feed on a wide variety of foods. The workers are partial to the sweet honeydew produced by aphids, scales, and mealy bugs found feeding on many trees and plants. Fruit trees, roses and many shrubs serve as hosts for aphids and may contribute to ant infestations in homes and other buildings. Most infestations inside are the result of workers searching for food. On occasion, a colony or part of a colony may establish itself inside a wall, behind brick veneer or beneath the carpet by a doorway. This ant will take advantage of any suitable, moist space to locate its colony. It is commonly found infesting rotted logs, stumps, and fence posts and may be found in tree holes and dead tree limbs far above the ground. Nests are also commonly located within piles of lumber, rocks, bricks, and similar items.
Infestations of little black ants often require patience and skill to follow the trails back to the nest. The type of treatment used depends on the location of the nest. Baits can be effective but require persistence and follow-up to achieve results. You should eliminate piles of lumber, bricks, or other debris that could serve as a nesting site for ants. Keep landscape mulch less than 2 inches thick and at least 12 inches away from foundations. Ensuring the sprinkler system does not spray directly onto the foundation and sealing as many cracks in the building's exterior as possible. Keep tree and shrub branches trimmed to prevent touching the building. Try to avoid using plants that are prone to aphids and similar insects. |
