If something is eating your peach tree leaves, set up bird baths and bird houses around your garden area. Put a bird feeder out too if necessary. The birds will take care of the bugs that eat your tree. It might take some time for birds to discover your bird sanctuary but once it's discovered you will have a small army of birds attacking the pests.
