Why carpenter ant activity is specific to Dunbar
Dunbar sees more carpenter ants per home than any other Vancouver neighbourhood we service, and it's not subtle. The neighbourhood's tree canopy — mature Western red cedars, Douglas firs, and big-leaf maples — keeps rooflines in partial shade for most of the day. Roof decks stay damp. That plus the heritage building stock (lots of pre-1940 Craftsman with cedar shingles and deep overhangs) produces the moisture signature Camponotus modoc colonies thrive in. Parent colonies typically live in dead branches of street trees; satellite colonies establish in roof returns, deck ledgers, and window frames. A single mature carpenter ant colony can send foragers 100+ metres, so if your neighbour has ants, you will too.

What to do right now
Book a carpenter-ant inspection before a second season — mature Dunbar colonies accelerate quickly once they establish a satellite inside the building envelope.
