answer:Oh, boy. Oh, double boy. Having tried everything that is non-toxic, my sister (down the road) has a huge fenced-in vegetable garden that has been overrun with woodchucks and their enormous families. First, no mothballs for anything. Here is the only solution. You buy three Havaharts at the local hardware store…check online for the proper size. You bait them with fresh cantaloupe. You do this only when you are going to be home for a while. You NEVER want to trap a woodchuck when you are out; the animal goes slightly berserk. Then you carefully put the trap in the back of the car and drive (rapidly) at least 7 miles to some nice woodland. Release the animal carefully (you may want to wear gloves). Leave immediately. My sis has caught five, not counting the raccoon (who also seems to love cantaloupe). Sunflower decapitation could be deer for the tall ones. Pepper, eggshiells, chimes, male and female urine are useless. You haven’t yet spotted the slugs and Japanese beetles? Put on your reading glasses and have another look. You are not alone, if that is any consolation. Probably not. If you open your window, you can probably hear my sister screaming. I have also problems with opossums, skunks, chipmunks, squirrels, mice and voles. Where do you live? How much acreage do you have?
