Second time I had to do it. If I didn't kill the fucker, and it can tolerate the stinking hole still, then I'm going with a trap. I have a Hav a Hart trap, but at this point, I'm out for blood. If I see the hole is dug out again, then I am going to use 2 foot traps. One near the hole w/ some apple 1/4s in and around it, and one upside down over the escape hole, so it clamps on his fucking head. If I get him either way, I'm going to ask my neighbor if he wants to bring over a mastiff and make a youtube video. One time I shot a woodchuck in the belly w/ a cheap crossbow pistol. Nice sounding thud when the bolt hit. Thing musta died in that hole after the wound became infected, because no wood chuck ever went near it again. It is too dry this year, but another technique I've used is to put the discharge hose from the sump pump into the hole and flood/drown the fucker out. I wouldn't care too much, but the fucking ground hog is digging in and around my horse's run in shed and fucking up the siding. If he stayed in the hedgerow on the side of my property I wouldn't bother killing him.
