Carpenter ants are large black ants. Some of the workers can become a 1/2 an inch or more in length. In Holmes County, Ohio, there are probably four different species of carpenter ants. Most are black but some will have a red head.
Termites rely on wood for their nutrition, but carpenter ants cause damage by eating the wood in order to make room for their nest. They will hollow out large areas of the wood structure in the house or other building. If you see little piles of wood or sawdust, there are probably carpenter ants present.
Most of the time the carpenter ant colonies are in the soil or in a tree, but you can also find them in railroad ties, tree stumps, firewood, fence posts, porch pillars, window sills, behind downspouts, under a leaky toilet, near a laky pipe and other areas that are prone to moisture.
When the colony becomes large, part of it will move to a new location, (like your home) and set up a nesting area. These colonies can become very large and may cover your yard as well as the neighbors yard.
To provide control, one needs to find the nest or nests. Treating the nests directly works well and then total house treatments are the best way to eliminate the carpenter ants. The treatment must be extensive and cover the whole area. Most persons are not equipped to do the extensive treatment.
The small round ant bait stations do not work because the bait is designed for different types of ants.
