Why are bats good? In California almost all bats eat insects -- lots of them. Bats naturally control insect pests, like moths, flies, beetles and mosquitoes. Many bats eat half of their weight in insects each night to stay alive and healthy. Nursing mother bats may eat their full weight in insects each night. They are such efficient hunters, that they can catch this many insects (up to 1,000/hour) in a mere three hours on the wing.
