How Much A Is Bat Worth

Study: bats take a billion dollar bite out of crop pests A bat is worth its weight in gold -- or, according to new research, at least their weight in corn earworms. With crop pests taking $1 billion out of the farm economy every year, farmers can be grateful for the pests that bats take out of their fields. New federal research shows that the leathery-winged flocks consume a healthy portion (for them) of corn earworms as they migrate through the corn belt in sync with the emergence of the crop pest. That has some calling the bat a natural pesticide. Others just call it the billion dollar bat.
