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.
Size: These are typically large ants up to 5/8-inch long. Carpenter ant queens are about 3/4-inch in length, while the males are smaller at 1/2-inch.
Color: Their color varies from black, brown & black, red and black, to light brown depending on the species. The two most common pest species are black in color.
