Carpenter Ants are ¼ to ½ inch long black or reddish-black pests (there are also slightly larger, winged reproductive forms that leave the nests in spring and early summer) that destroy wood and wood-like structures in and around homes, while giving painful bites to humans.
Carpenter Ants leave slit-like holes when they enter the wood, which they use as a nesting place. Piles of sawdust may be found around wood structures such as porches, attics or support beams. While beneficial in nature, they can be destructive to structural timber, ceilings and floor areas. They prefer moist, decaying wood. Look for foraging carpenter ants at night with a flashlight and a red cellophane covering.
While the insects can invade the home, Carpenter Ant nests are always located outdoors where the queen lays its eggs.
Carpenter Ants are found throughout the United States.
