this might be helpful.I got it from a local gardener who got it from a farmer. She swears by it and has used it without fail for many years. It may have appeared here before, but it's new to me.

Break a dozen eggs in a container and beat them to a froth. Let them sit for days until there's a good strong sulfur smell. Mix with a gallon of water in a sprayer and mist around the problem areas. The plants don't have to be drenched, and it doesn't wash away with the first rainfall. Eventually, the deer simply stopped coming near her yard altogether.
