Little Black Ant

Little black ants are usually seen around homes following well-defined trails between the nest and food and water sources. They feed on a wide variety of foods, but the workers are partial to the sweet honeydew produced by aphids, scales, and mealybugs 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. 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. 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. For minor infestations ant bait traps are effective.
