I love bats too but smart enough not to mess with them. We would open all doors to get them out of the house. We had to turn the TV on mute because hubby said it may have been confused with the echo signals, that it was not able to detect the openings of the doors. I do not know if that is true but our house is old and has smaller rooms than normal modern day homes have.
It stumped me still how it got in. I don't see any bats flying out of our house, thought it would be the eaves of our house but nothing came out of it at dusk. The only two things bats are getting in our house, are the chimney (already had a cap on it) or coming in while daughter came in from playing outside. Why of all places must they come in the house?!
Daughter was upset because we could not keep that bat as a pet. I told her they are best as wild animals and treated like such and respect them for being wild to catch mosquitoes and insects that we don't like.
