Groundhog issues

So I live South of Boston in more of wooded area and we get all type's of animals here ranging from "Deer,Fox,Rabbit,Hawks and Groundhog's" just to name a few, and the little fuckers are kind of destorying the yard and I'd love to get rid of them peacefully if possible . Does anyone know of a spray or something that would scare them off 

Thanks
