I had bats last year. Thankfully my landlord had a company come in and make it so they can get out but not back in. We watch them in the backyard every night. They are okay as long as they are not flying above my head while I'm trying to sleep. I was so scared and alone when that happened. I was glad my cell was next to the bed so I could call a friend to get it out. The second one was in the living room and I watched it go out the bottom crack in the door. Hissed at me the whole time. Yuck!
