So what’s so important about bats?

Most notably, insectivorous bat populations may be worth billions of dollars every year to North American agriculture. Estimates of their value to the U.S. economy, specifically linked to consumption of insect pest species, range from $4.6 to $23-billion annually. They are an important but (due to their nocturnal activity) frequently overlooked component of sustainable agriculture. Attracting the right species of bats can help get rid of insects that target grape vines, nut trees, and other crops and thus allow farmers to cut back (and save money) on pesticide use.
