Good tip, RdFx.
I almost exclusive make bank blind and dirthole sets for mink now, and occasionally put in a pocket set. Areas I trap are generally low-grazed pastures or farmland with small creeks, mostly predator trapping. I catch most of my mink in either dirthole sets, or by specifically setting #110s in blind sets near the stream edges, fencerows that meet creek areas, anywhere I find some mink tracks. I also leave a set or two at rat runs long after I've taken the last rat or so from the run...the set sits empty for several days but I've taken enough mink at the now empty runs that I'm convinced its worth the wait and leaving traps a bit longer after the rats quit coming.
I can't remember the last time I made a bait set just for mink!
