How to flush out a groundhog
Alright I have a real problem.A whole community of groundhogs has just made its home in my dams retaining wall. I have counted around five separate holes in the wall and have tried to smoke them out with around 5 separate smoke grenades, but apparently the tunnel system is much like the Viet Cong and are just to vast. I need to nail these rodents ASAP before they break through. Any help would be great thanks.
