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.

To supplement the other answers that recommend a one-way pest exit door based on the comments that the current hole size and location will not accommodate such a door: You can always patch the current hole, create a new one for the door (preferably in an inconspicuous location if possible), and then either remove and patch up the new hole after you are sure all pests are gone or leave it in place should pests find a new entryway in the future.
