It will dig tunnels in your pond dam or bank about a foot under water. Buy a head trap and mount it over the hole. Do it yourself because you may have muskrats in the future so it will be handy to have the trap available. If you are vigilant you could shoot him if you catch him on the bank. If you shoot him on the water remember that the bullet could deflect off the water and end up who knows where. The head trap is the way to go.
