natural repellants for groundhogs

Question

Is there something natural, like jalapeno peppers or Tabasco sauce, that might deter groundhogs? Marigolds work for bugs. Groundhogs seem to like them though. I have one burrowing under and into my crawlspace and I don’t want him there! How about mothballs? Is there something that will work?? HELP!

Oh yes, and bats too. What might repel them from my back porch?? SIGH~!
