Jonesie, here's the deal. You make sure to tell everyone that they need to trail your skunk lure at least ten feet in either direction from the two doors of the Comstock cage and that they need to put a least a half a bottle underneath the triggering wires. Don't thank me, just send me a check. ( And don't tell me you're too busy making skunk lure )

We have set and used mostly 7x8x24 safeguards for skunks for many years with very good results. Both in posi sets and open area set ups.Gang setting is our key with a variety of set ups/odors on different locations using the wind to your adavantage as you should.

Like Eric and LT said it is a balance of presentation, visuals and good odor selection as it is for most trapping.
Forced / guided trapping is a slam dunk most times. For open area grubbing problems "gang setting" is a given procedure. I shy away from larger traps to reduce raccoon catches unless it is the target animal and in some grubbing cases it is both animals that must be taken out. In those cases both size traps are used.

Use what size traps that you are confident in using and you think is needed to get the job done. That is the key to being a productive ADC operator. Adapt and improvise as needed.We all have had avoidance problems and having to deal with nomadic visitations always being a problem. Or the skunks decide to leave the site the night before we set up a job never to return until we have pulled the job. I am sure no one has had that one occur yet.
