[Right Wing Assault]

I put a road-kill squirrel in their hole.

I did that too! The squirrel disappeared and the groundhogs stayed, so I think some critter ran off with the squirrel before the hogs noticed.

I heard that they are very fussy about their burrows and if you pee in them, they move out. I tried it and they never came back.

I pounded in rocks on top of the squirrel.
