Wait a minute!! What the hell size are the woodchucks which need THIS???
The 38 'chucks I have killed over the last 6 years all went down with .22LR, delivered neatly to the head or through the lungs.
Of course, if you can't AIM, then larger weapons are humane.
Glad it worked so well for you. But the suckers out this way take more than a .22.
The mosquitos get kind of surly in the simmer, too.
And as for the groundhogs....
I remember being out in Oklahoma and wishing I had a Stinger for every mosquito that buzzed me.
They were much too big for swatting to be effective, and bug repellant was apparently maranade to them.
Mosquito Squadron 52, the ones with the big red eyes and dun brown bodies.
I'm told they're still there.
As for the groundhogs, I'm glad we don't import them this way.
The ones we have are evil enough.
