I've found the Garden Scarecrow chases everything away from plants, except underground animals. You can set it to different heights, and I set it high to chase away birds from my raspberries. But we could see tracks where different animals, including deer went running when I left it on at night.
It won't hurt any animal, just at the most get them a little wet, but it's very effective.
