Create a welcome environment for bats in your garden. You know, those ugly creatures you see in the horror films.
Bats love to eat bugs.
It is said that a bat will consume the equivalent of it's body weight in insects every night. It is also said that bats seldom eat insects that are beneficial to your garden. Since bats cruise around at night, they eat a large number of moths and other night flying insects. Many commercial fruit growers install bat houses in their orchards to help with insect control. I've got to admit that I really don't know much about bat farming, if that's what you call it.
