Beav, I'm surprised that you are unsure of the dps for skunks. We have great luck using them up here. But maybe there is a difference between your skunks and ours, kinda like muskrats on floats in the fall from one region to the next.
What are you using for bait?
5 gallons of cheap cat food gets 1 pint of fryer oil, 1 bottle of sweet baby rays BBQ sauce, a hand full of fish meal, and a coffee can of lucky charm marshmallows. To compliment that I use a 28oz gatorade bottle that gets 1oz of cavens mooshine, 1 healthy squirt of liquid smoke, 1 squirt of fish oil, 1 squirt of beaver sac oil, the rest is filled with more fryer grease. I keep a 4oz squirt bottle filled from the gatorade bottle and use a healthy dose on and at each set. Always 2 traps or more per location filled completely with bait.
Pretty much any general location will work when it is warm but as temps cool, being as close to denning areas produce better for skunks. 66 DPs and 88 pounds of bait has equated to triple digit numbers of all 3 targets, racoon, skunk, and possums.
If skunks are the target then you kinda gotta forget what you know about coon spots and spend a little time looking for skunky spots. Junk yards, old abandoned bldgs, round bale stacks, dry culverts, rock piles, piles of debris, old log piles, the closer to people with gardens and mowed yards the better.
How you orient the trap for a short animal to comfortably access the bait is also something that will help.
