Squirrels are evil, vicious vermin.
They will eat your entire garden.

You had 6' tall corn stalks, just starting to put on ears? Now you have a bunch of corn mulch.

Also, these things have a bite.
Their front teeth are designed to bite through nuts. Hard nuts. They will go through your leather glove and through your finger.

They will figure out how to get into anything solid with no holes anywhere. They will push wire out of the way, leap from trees ten feat away or burrow underneath to get at your tender vegetable garden.
