I tried using several different repellants around my landscaping but nothing works on the mature deer.- This one buck is destroying thousands of dollars in small trees I planted. He bends them down to the ground and rubs the bark off everything. Forget the 120 Junipers ruined the year before, they eat the limbs up to the 6 ft level and never grow fast enough before consumed again. His big fat companion eats my Holly bushes to the last leaf by Feb each year. I'd shoot the SOB but I need someone to come get it afterwards. If it dies anywhere on the property my dog will eat it and roll in whatever is remaining (isn't that nice). Years ago I allowed someone to hunt on my property. He shot the deer using a Bow & arrow and the deer took off after being shot, this guy was so lazy he didn't track where the deer ended up which was later found in the woods, my dog dragged one of his hind legs home to chew on. My goofy neighbor says he hunts but never around home, he wants the rack but not the deer if I bag him - yeah right!
