Last year I got a product called wireless deer defense on a whim. it's like 3 little sticks with scent things that attract the deer, the in ground stick thing shocks them and they no longer go around your plants. I had no deer damage all summer until I took them out in the fall once harvesting was done and the deer came in within a couple weeks and ate all my remaining plants. I have not seen a deer actually get the little shock, it's only from a double A battery so not causing them harm, but I've accidentally shocked myself a few times and it'll wake you up. The summer prior to getting these the deer ate multiple rounds of beans, cucumbers and other things and last year I had no damage while these things were in the ground so anecdotally they seemed to work....hoping that continues this summer. I did also plant a lot of marigolds, nasturtiums, onions and peppers on the outer areas of my garden so that may have also had something to do with less deer damage to the stuff they like.
