A few evenings ago at my sister's house (I was sleeping in the finished basement) I was startled by a very large bat. It flew into the enclosed laundry area so I shut the door. And we had not seen it since.
I talked to my sister about it and she likes the bat.
They've had a few in the basement and when her husband kills one of them, she starts seeing bugs in the basement. When there's a bat, it eats the bugs.
She says, "Better the bat I can't see than the bugs I can see".
But then...I like bats. Bats are the good guys. One bat in one night will eat a whole grocery bag full of mosquitoes.
