Carpenter ants are highly adaptable and capable of establishing nests in diverse environments. They most commonly occur in wooded areas preferring to nest in a moist, humid environment. They nest in live or dead trees and stumps, dead tree limbs, buried wood, in firewood, fence posts, landscape timbers, tree holes, hollow wooden doors, ceiling beams, under roofing boards and attic insulation, voids above windows and porches, under rocks, logs and other objects on the ground.
Effective control can be achieved if the parent colony and all satellite colonies are located. A thorough inspection should be performed to determine where the ants are nesting. Moisture is the most important factor in attracting and sustaining carpenter ants in structures. All water leaks should be eliminated.
