I have a low pitch roof that has an attic between it and the ceiling which is low enough to be useless for storage and access. I have had a problem with squirrels entering for a while and I finally found the hole they are using to enter. I would like to plug the hole but would not like to leave any squirrels inside to either try to dig another way out or go crazy while waiting for inevitable and slow, awful death.
Is there any way to lure them out before I plug the hole? They can be heard moving in the ceiling sometimes but an absence of the noise does not guarantee they are not inside.
