The first thing to consider when trying to figure out how to get rid of carpenter ants is to determine that they are in fact carpenter ants. One way to do this is to find pictures of carpenter ants and compare them to your invaders.
Carpenter ants are unusually large and black-ish in color. Some female carpenter ants have wings and are commonly mistaken for termites. Another way to determine that you have carpenter ants is to analyze their characteristics, habits and dwelling locations. Carpenter ants are generally nocturnal, meaning most of their activity occurs at night.
By activity, we mean coming out of the nest to look for food. They usually build their nests in soft, rotted or rotting wood. They prefer moist conditions. This could include any type of wood, inside or outside.
