Why carpenter ant activity is specific to Kerrisdale
Kerrisdale carpenter ant activity sits between Dunbar's extreme and Kitsilano's neighbourhood-wide baseline. The neighbourhood's housing is a mix of genuinely old heritage stock (pre-1940, often with cedar-shake roofs still in original condition) and newer 1970s-2000s rebuilds on the same lots with modern envelope detailing. Colonies concentrate in the heritage blocks. West 41st, West 45th, and Marguerite see the most callouts. Mature gardens with big-leaf maple and cedar street trees drop moisture onto rooflines year-round. We also see a lot of satellite colonies in hot tubs and outdoor kitchens — luxury renovations are a surprising carpenter ant magnet because the new softwood framing behind the cladding holds moisture during construction.
