We live in a state park and so have a lot of critters around. There is a painted foam covering on the cement block foundation of our home. The problem is, the chipmunks have absolutely ruined it. There are holes in it everywhere where they have eaten into it. I need something to cover it with that the animals will leave alone. I saw something on HGTV where they covered the cement block with cedar. Would this be a viable solution? I know that cedar repels insects, but not sure about animals. Please help!
