They work on marten so I know they will work on mink
Muskrat or duck would be your best bait
I am not so sure they are going to work on mink. Mink are a lot tougher then marten so I do not think you can draw conclusions from any success marten trapping.
I do not know anyone who has caught a mink in one. The only way we will find out is with a little experimentation. I hope we will hear the results of anyone trying for mink.
My suggestion: I would set the traps where if they prove to be not lethal the mink would drown. Mink sets typically go near water anyway so turning it into a drowning set if the mink remains alive should be easy enough.
