How often are you guys changing out bait in cubby sets for fisher? Currently have some boxes out that are baited with venison scraps. 1-2 pounds in each box, have been out for 2 weeks now. It’s been highs in the 20s and lows in the teens to sub zero temps at night. We now have had a warm front that is lasting 4ish days with highs in the mid 30s but still lows in the 20s. Should I worry about changing my bait out? There is still plenty of bait in each box, haven’t been hit by mice too hard, and i can’t smell like tainted meat or rotten meat when I’m checking.

Unlike many, I actually prefer tainted bait for marten, the only time I change it out is when it gets freeze dried. I try and avoid fisher since we don't have a season on them, but from my experience they have similar preferences to marten.
