My parents attic was a bat haven. Every once in awhile one would get into the house. I’d just put thick leather garden gloves on and GENTLY pluck them off the curtains. Then carry them outside, hold them above my head and let them go.
Bats can’t take flight from the ground(putting them on the ground is a death sentence), so you have to give them some height so they can glide away. Just thought I’d share this in case anyone gets a bat trapped in their house.
