I know a great way my grandfather told me about that his father used. Just take a bag of salt and pour on the stump. When it rains the salt soaks into the stump.(be sure to use plenty of salt) When the salt soaks in animals (mostly deer) will come to get the salt and eat away the stump until nothing is left. Butif the stump isin your front yard where deer most likely dont want to be then this probably wont work.
