Anyone know of proven snake repellent? I have heard of everything from moth balls to lime, I even heard to throw golfballs out and snakes will eat them and die from digestion complications (this doesn't make any sense to me because snakes rely on other senses besides sight when hunting and would be able to tell the golfballs are not a viable food source). Its getting close to the time snakes will be popping up around the yard so any ideas or tricks would be appreciated.
