It’s common to make homemade raccoon poison by combining poisonous fly bait with Coca-Cola to mask the taste, but doing so puts other animals at danger and is not recommended. Cats and dogs have been reported to die from homemade raccoon poison.
The most popular homemade raccoon poison recipe is for combining an insecticide like methomyl with Coca-Cola. Animals are drawn to the deadly cocktail because of the soda, and the insecticide poisons them after ingesting it. Even though raccoons can be killed by such a poison, it can also kill any other living thing that comes into contact with it, including household pets. A raccoon killed in this way will likewise poison any animal that eats it. For these reasons, raccoon poisoning is strongly discouraged by animal control professionals.
