Good way to rid squirrles digging in my garden?

Sit on the porch with a BB gun and educate them one squirrel at a time. Want to educate them faster? Use a pellet gun, .177. Use a .22 pellet gun and you will be a better educator. I have tried all the remedies in the world and have still suffered from squirrels. Lead poisoning is the most effective but you will still have occasional problems.
