My mother had one come into her apartment several times (well not sure it was the same one). Several times she called the local police who came and tried to get it out. One time successfully using an old paint can. That one had paint on its wing so we don't think it was always the same bat. Another time the cop wasn't successful and Mum said that everytime he opened a cabinet door or something, he'd scream if he thought he saw it. That alone was worth it to her, she got a good laugh. Another time I was home and my Uncle was visiting. Mum and I were screaming like idiots everytime we tried to venture out of her bedroom. My Uncle never came out of the room. Next morning we tell him the story, turns out he was awake and heard the screaming, but thought it was the neighbors.

I appreciate their importance, but I too do not want bats in my home. Neither did our cat.
