Insect size ranges from 1/8-inch to more than 1/4-inch in length. The most commonly encountered species are found at the smaller end of this size scale. Their colour ranges from black to dark brown to red and black. The smaller species are typically uniformly dark in colour. They feed on a wide variety of foods, and may contribute to ant infestations in homes and other buildings. Most infestations are the result of insects searching for food.
Colonies of insects are most often found in tree holes, dead limbs, stumps, and logs. Rotting areas in fences, decks, and railings may also be nesting location. Inside the house, such insects are typically found around the perimeter — in soffits, door frames, and skylights.
