I think the free Going Bananas came from Michigan Bulb that is who sent me one. I have used Deer Off spray that seems to work well. You can make your own version it works but is something you need to do outside , smells really bad. Boil a pack of cigarettes garlic and a bottle of hot sauce in a gallon of water. Strain through cheese cloth. A pack of small cigars are a lot cheaper then the cigarettes. Human hair is also supposed to work.
