Our family doc told me a story about when his brother was a toddler. They were at their lake cabin and his brother kept getting out of bed, crying. Finally their dad gave him a swat on the rear and a bat flew out of his diaper.
Our creepy crawlies are just bigger.
Oh, Yes. I used to have an old farmhouse and bats were always an issue. One fall I had six of them in the house at once!
Well, seven - much later I found a dead, crispy one behind a bookcase.
It cost me close to $10K to clean, sanitize and re-insulate the attic once all the cracks were filled to stop them getting in!
