There are so many raccoons in the city of Toronto, its known as the raccoon capital of the world. Living in such close proximity to humans is very beneficial to raccoons, the're never far from a fresh meal, seemingly knowing when garbage night is. Raccoons are climbers so its inevitable that they get into uncapped chimneys and roof vents. The best way to keep raccoons out of an attic or chimney is prevention screening. Some people take the long way getting to this point, first trapping and relocating the nuisance animal, then cutting down trees around the house thinking this will solve their problems. Raccoons can climb drain pipes so keeping them off a roof it not the answer. Prevention screening installed by a professional wildlilife control companie such as AAA Affordable Wildlife Control , will out last a roof and keep raccoons out of those areas for years.
