Bats are protected by the migratory bird act of 1918. They cannot be harmed. Instead, we must seal up building to keep them out. If bats are already nesting inside of a building, we must wait for them to fly south in late fall and seal up the building then. Sealing a building requires a lot of inspection work to make sure every opening is found and sealed.
Thorn also performs clean up of attic spaces when necessary.
