Attracted to moist wood because it is easy for them to tunnel in, carpenter ants often begin a home infestation in areas of moisture damage and wood parts of homes that make ground contact.
Damaged Wood to Good Wood
Tunneling often leads carpenter ants into undamaged wood to gain space for an increase in the colony size. They don't eat wood like termites; instead they simple hollow it out for nesting.
Boring from their original infestation point often leads the ants to structural timber, which can compromise the structural integrity of the home and lead to costly repairs.
Diversity is a key attribute of carpenter ants that makes them difficult to control. They have multiple colonies and can damage a home in several different locations at one time.
Woodpeckers will pursue carpenter ants as a food source, damaging exterior wood in the process.
