NMB in crawl space

Bats? What bats? I didn't see no bats!

The worst thing you can get in an unsealed attic is a bat problems with bats living in the attic.

You can't just go in and remove or kill them because there are laws and serious fines for disturbing bats. So you have to hire certified bat removal service. This can run into many thousand of dollars.

You can think you have the space sealed and still have bats, they don't need much of a hole to enter.
