There are ecological superheroes at work in our midst. But, like all great superheroes, bats are misunderstood and in jeopardy. As they fly through the night skies, bats save U.S. farmers over $23 billion annually. Yet, many in our culture are completely unaware of their benefits – or the dark force which has risen to threaten the very survival of their species.
Bats streaming through the skies at sunset after emerging from Bracken Cave.
Just outside of San Antonio, Texas; Bracken Cave is the migratory home to over 20 million bats. They emerge, shortly before each sunset, as a powerful force for local agriculture and a jaw-dropping aerial display – so immense it’s visible on doppler radar. These amazing mammals can fly hundreds of miles in a single night to hunt the insect pests which might otherwise decimate area farm crops.
Further north, over a million bats depart through twilight from underneath the Congress Avenue Bridge of Austin, Texas. Every evening from March through October, tourists watch in awe as this important colony of bats streams over Lady Bird Lake en route to surrounding corn and cotton fields. These hunting flights save the region’s farmers thousands in pesticide expense alone.
Appreciation for the ecological beauty of these creatures is on the rise, but in the depths of their caves, White Nose Syndrome attacks bats around the world as they hibernate. This fungus has already caused a 99% decline in bat populations in some areas. Fortunately in this battle of good versus evil, science has discovered a reason to hope for the future of bats.

Settle in for an awe-inspiring look at these tiny animals, the extreme measures being taken to preserve their species, and the ways these powerhouse hunters can go to work in any home garden. Each of these creatures is small, but their collective actions are colossal and transformative. The same could be said of our choices, as we each take our individual steps to grow a greener world.

We have two bat houses attached to our home. In the past, they have been occupied. We noted that wasps find these homes very attractive. Now that it is winter should we clean the bat houses and if so what should we use?
Will the wasps keep the bats from their homes?
Is there annual upkeep for the bat house?
Thank you,
Katherine Cooper
Attitudes are changing thanks to yours, and many others efforts. There must be an answer found for this disastrous fungal disease.
THANK YOU
We’ve had a bat house for about three years it never has been occupied. I contacted a “pest removal” expert in our area and asked if he could relocate bats to our bat house. His answer was that bats are routinely euthenized in our state according to law.
