Have you tried one of those essential diffuser things, and use peppermint. Powerful smells like that “blind” rodents because their main sense is smell. We also couldn’t get the tap dancing chipmunks to get out of the attic. Tried everything, peppermint essential oil worked for us. Tried the things made for rodent repelling that smells, but they don’t really work as well. Lol

Poison can kill nontarget animals, pets, owls, hawks, foxes, etc.
