Electric fencing can keep mink out.
18ga. stainless conductor 4" off the ground. Using a weed cutter (don't remember the brand) charger, suppose to be good for like 50-100 miles of wire. i do know that I have been hit with it a couple times. Makes my eyes go white, bite my tongue, and I stay sore for a couple days. Leaves a burn mark too!
I have actually killed mink on my electric fence. They hit the fence, being as mean as they are, they turn around and bite at the wire. I guess the electricity locks their jaws. Find'em smoldering dead on the wire.
What is premier perma fence?
