Some studies have estimated that service to be worth over 3.7 billion dollars per year, and possibly as much as 53 billion dollars per year.
This value does not take into account the volume of insects eaten by bats in forest ecosystems and how that benefits industries like lumber. It also doesn’t take into account the importance of bats as plant and crop pollinators. So the actual monetary worth of bats is far greater than 3.7 billion dollars per year.
