Squirrels on my Lawn

Ok, I hear you saying, "it's a lawn with pock marks, so what?" You forget; we live in pretty dense woodland and we have many many squirrels hereabouts. And we have had a particularly warm spell this week; it went from zero degrees Fahrenhait to sixty within day or two. Put those two things together and you get a seriously chewed up lawn as the squirrels emerge to try to recall where they buried their stash in The Fall, grab a quick bite to eat and chase each other up and down the trees before returning to their nests before temperatures plumment back to freezing. This they have now done. Last night's frost has solidified the squirrel's pock pattern, and tonight we expecting a pretty big dump of snow; 4-6". The good thing is that the lawn will be covered for a fair stretch now.
