I hate to say this because I'm sure it wasn't much fun for you but, your story is HYSTERICAL!!
!! i was laughing to myself reading it!! I had like this movie going on in my head
You made my day!! Try plugging up the holes where they are coming in...Bats can carry rabies...I would get a big fishing net...this would make it easier to catch the little buggers...they do fly fast...I had one in an apartment many years ago..I thought I was going to have a heart attack!
Good Luck...I hope your day is better than you night was
