Cover up potential entrances, such as uncapped chimneys, loose shingles and openings in attics, roofs and eaves. If you are not sure where raccoons are getting in, sprinkle flour around potential entrances and check for footprints later. You can also stuff a rag or ball of paper in a suspect hole and check later to see if it has been removed. Make a raccoon den unlivable. Sprinkle moth balls around the area or hang ammonia-soaked cotton rags near the entrance and keep the area brightly lit.
Raccoons dislike loud noises, bright lights and strong smells.
Use the same methods in your garden or in the area where you keep your garbage or composter. Do not move a trapped raccoon to a new location. You could help spread the disease. Do not touch dead or sick animals. Use a shovel and wear gloves if you need to dispose of a dead animal.
