Beginners Gardening

I want to have a group of squirrels defend my garden from moles, chipmunks, deer, raccoons, nutria, bats, children, etc. Any suggestions on how to do this?

I live in Atlanta Georgia. I am going to put up to a couple of hunder worms in my garden. I would like to put a type and quantity that will survive until next year. Any suggestions on quantity and type ?
