Moth ball time...Tie 4-5 in old socks or woman's hose, make up
5-6 of these and tie in cedar trees around his stand...Find another area to hunt for the rest of the year...You can remove after the season...
I wouldn't waste my time or breath talking to him or the GW...This guy knows exactly what he's doing, doesn't want to scout or learn to hunt...He saw your stand and said "Screw him"...I'd return the favor...
