For the past 9 years, I've been sharing my vegetable garden, fruit trees and flowers with the local deer without any choice. I've tried every possible natural deterrent without success. I even tried this horrible blood-based product that required steeping and straining. (I'm pretty squeamish, but I was so very desperate that I even resorted to this process.) After the deer chewed half my roses down one night, my next door neighbor came over on my birthday and sprayed the other six rose bushes with Deer Stopper because he wanted to know if this product really worked. I knew that after an attack like this it was just a matter of time before the deer came back to get the other six. In fact, they tried to chew them the very next night. There were hoof prints all around the six untouched roses and one broken branch on the ground. Apparently, they didn't like the taste! I've sprayed the roses three times in the past month (because we've had rain) and for the first time in 9 years, I have a beautiful ring of red roses...no more nibbles, unwanted deer pruning or damage. Plus Deer Stopper smells pleasantly of mint and herbs! Deer Stopper is the best birthday gift for a gardener!
