There is a resident doe who thinks that everything around my house is part of her buffet. If it were not for the fact that she has fawns, she would be venison. I have tried a half dozen different commercial products with little success. "Marking" my territory only seems to make her laugh, plus the Princess refuses to eat the tomatoes. So far the best repellant is when I hang my days worth of sweaty, stinky, work clothes around the house. The Princess is like, "What will people think when they see your underwear hanging out there?" My reply, "Who cares, and at least they will know that I wear underwear." Anyone have repellant ideas that keeps these giant 'rats' away?
