What is a natural raccoon repellent?

Ammonia acts as a natural raccoon repellent, according to HowStuffWorks. Its strong smell aids in warding off raccoons that may try to invade homes and garbage cans. Rags soaked in ammonia can be placed wherever raccoons live.

Other natural raccoon repellents include spices such as cinnamon, ground black pepper and ground dried hot pepper. When a raccoon smells strong spices, it becomes irritated and moves onto a different location. Peppers and onions are natural deterrents. Hot peppers, cayenne pepper and onions can be boiled in water. The water can then be used as a spray in areas where raccoons are not wanted. Other simple raccoon repellents include bright lights, loud sounds and water sprinklers.
