This is very concerning. I remember when I was a kid it was very common to see bats at dusk and early evening. When playing late outdoors we would see bats fly past by watching the street light as they came on. I remember my mother carefully removing a bat that had somehow got trapped on our back porch and explaining to me how beneficial bats were to our health.I heard about this disease killing bats several years ago and am surprised that nothing has been done to successfully  eradicate it.
