AMERICA’S BATS ARE AN ESSENTIAL PART of a healthy environment. Nevertheless, many bat species are in alarming decline, largely because of unwarranted human fear and persecution and the loss of natural roosts. You can help by putting up a bat house. You’ll benefit directly from having fewer yard pests and will enjoy learning about bats and sharing your knowledge with friends and neighbors. Few efforts on behalf of wildlife are more fun or rewarding than helping bats.
