We put out several pallets of sod for a client back in October. He called me last week and said that he thinks some animal has been turning over the corners and edges of the sod. I went by to see and, sure enough, numerous corners were peeled back 4-6 inches and a number of the edges were pulled up. One of my buddies suggested it might be moles, but there was no evidence of burrowing. I couldn't see any evidence of digging either. The property is surrounded by woods (oak trees) and there are a lot of acorns on the ground. Another buddy suggested a squirrel or a raccoon. Has anyone had any similar experience?
