Penn State Extension's carpenter ant guidance connects nesting with moist or damaged wood and explains that carpenter ants excavate material rather than consume it as termites do. That distinction matters when an inspection considers wood damage. It does not mean every ant sighting indicates a damaged structural member.
Use the identification to guide the next question. Is the evidence consistent with carpenter ants? Is nesting confirmed or only suspected? Is the active area accessible? Ask for the reasons behind the conclusion. A property-specific finding is more useful than assuming that any large ant in an Erie house requires the same treatment.
