I also have used Deer Off. I used it for a couple of years when I had hundreds of hostas. I knew that I was one day past when I should have sprayed again.I go out the door and find only hosta blooms, no foliage at all. Put a date to respray on your calendar and Deer-Off will work well, or make your own. The recipes with eggs and peppers and garlic with some oil or "sticker" work just as well and are much cheaper.
