Marey Mo: I had a huge patch of mint by my house and still had possums, raccoons, and skunks right up next o the house. I have killed a couple of possums with a ball bat, but wouldn't mess with a coon or skunk. Usually had to call my husband to come and shoot them, so the mint doesn't always work either. We had enough mint around there we should never have and any varmits anywhere close.
