My dad while he was still with us would tell the story (possum)
this works on all the critters that want to make your home theirs
one night (when my dad was a boy on the farm) the chickens erupted into a ruckus.
his dad and the brothers went outside to see. yes the three legged dog went to (lost a hind leg to a badger many years before) there it was the dog got to it first. yes it too was now playing possum. they tried shewing it prodded it with a stick, a gun, kicked it too.just played dead while the dog sniffed it. nothing they did had any effect, moving the old possum along.
well sir grandpa wanted to go back to bed. Mother nature stirred more than he could bare.
so Grandpa wiped it out. Yep he whizzed on the possum. Bam like a bullet leaving the muzzle of the varmint gun, ole possum ran off not to be seen again.
the moral of this tail, when all else fails ya just gotta do the unthinkable.
