Without following you around,I don't know.Some thoughts are,pullouts are over reported by new trappers.Most of today's traps,regardless which one you choose,hold coyotes.Most pullouts are from deer or freeze/thaw conditions and too light of pan tension.If there are multiple pullouts,most likely there is some other problem.Toward the end of the season,there are smarter coyotes but smarts don't get you out of a trap.
Coyotes also change with tbe seasons.The trapper needs to as well.EarlyFall,late Fall,Winter,Late Winter/breeding season,etc.Most places,breeding is starting.Most coyotes are'nt as interested in baits and food lures as they were.Where I am,they even use some different different traveways now.
If you are using the same sets,attractants and locations as ealier,you probably need to change up,in a big way.If you find those trails and few deer are present,you can slay some.I have gotten doubles and triples with blind sets on a short section of trail,this time of year
If too many deer,you might try a couple sets,off the trail with only droppings as the attractant.Make sure you have coyotes on each location before setting.Like I said,there often some seasonal changes.I am just throwing out some ideas.I am not there.Sometimes it is time to move or even call it a day.I would check your pan tension,at least.Good luck.
