The quick answer to whether squirrels in Canada can chew through to get into the attic is; Yes, although the animals prefer existing holes and will get in through these if available. Common examples include gaps under the eves and missing vent screens.
Wildlife primarily breaks into the attic to breed. This is a warm, secure and isolated space perfect for bringing up baby squirrels. The wildlife is more determined than ever to break in during baby season so they will create entry holes if none exist.
Squirrels have a good eye for weaknesses and will expand tiny holes or exploit rotting wood. The can sense air coming out of the attic and chew through the area to create an entry point. The animal only needs to fit its head into the hole and the rest of the body will squeeze through. Any hole 1 ½ inch wide or more is a possible entrance for the critters.
Like all rodents, squirrels are efficient at chewing. The chewing doesn’t stop once the animals have broken into the attic. Rodent teeth continue to grow throughout their life and they need to trim them often. This is the main reason for their destructive nature. The squirrels will continue to chew on insulation, wires, plastic piping, dry wall, trim, wooden support beams and much more. It is not unheard of for a squirrel in the attic to chew right through plastered ceiling.
