Carpenter ants

Carpenter ants are among the largest ants in the United States, ranging from 3.4 to 13 mm long. Similar to carpenter bees, carpenter ants are capable of causing damage to wooden structures. They cut spaces into the wood grain to form nests and provide passageways for movement from one section to the other. They do no eat wood so theyre not as destructive as termites, but their presence can still be a great nuisance for home owners.
