When we lived in Maine we learned so much from an 'old timer' who knew the ways of country living. We were way up on a mountain in the woods and dealt with everything from a mountain lion to deer, to moose and racoons. After all these years, it made me nostalgic and amused to find that I still want to share two of his greatest tips to keep animals out of the garden.. a 2-3' high chicken wire fence.. laid flat on the ground will keep most animals out.. they are afraid of getting tangled in the wire.. or rotting onions from local store.. in bulk.. also laid on their side around the gardens. Appears they smell as bad to the animals as to us. Chicken manure on top of newspapers in the corn rows helps deter the racoons if you haven't tried the chicken wire. As for the beetles and borers, etc.. dry bran sifted over the plants is a pretty effective help. It sticks to their slightly damp bodies, dries and... umm..conquers them.
