The old man I used to work for when I was a kid always kept a box of matches on the mantle, next to his shotgun shells. I always thought they were used to light the fireplace until we went hunting one day and I saw him slip them into his jacket. We would find a likely place and he would gently shake that box and sure enough, a squirrel of two would show up. Pretty neat how that worked. I am going to have to try the quarters.
Squirrels are so dang inquisitive and destructive. You should see the damage they do to my barn and the number of feed sacks they rip open. I had left my medicine cabinet open and one had found its way inside and decided it was a good place to store acorns...
I am really surprised no one has come up with the age old answer to getting squirrels... I thought every youngster was taught this growing up... Just climb a tree and act like a nut!
