If you want to start fresh, soak them in vinegar for a day, rinse good, and set or re-dip. I just think you’re trying to blame something either you KNOW is the problem, or you’re overlooking the obvious.
My son had some issues and we straight up swapped traps. I even used his traps on his property and caught. His “solid” and my “solid” weren’t the same. We now “BOTH” solid now and catching, lol.
If you’re catching Greys and using dirt holes then maybe your sets are too close to the bait/hole. Maybe a coyote or cat is coming up and going to “dig” the hole and uncovering the trap. If I want fox or setting for fox I set close, everything else gets set farther back. Possibly an issue.
"I just think you’re trying to blame something either you KNOW is the problem, or you’re overlooking the obvious." Possible, but even though I may know the problem or am overlooking it the problem is still there and I have not identified it. I am thinking that even though I am using blind walk throughs for Bobcats I am leaving scent that coons or coyotes are picking up on. Same for dirt sets, so I have refined my process to be as clean as possible for all species if that makes sense. My dug up cubby holes are probably coons.
Now I never considered my trap being to close to the bait hole. That is a strong possibility. I have been watching many youtube videos and I know my sets are bedded as good and probably better than what I am seeing. Deer can be a problem and I have seen deer tracks around my sets as well as coyote.
I will be checking for seized pans, possible thinning down of the mixture may work better in regard to seizing as I have not noticed anything when thinning.
Not using formula 21 degreaser. I used vinegar.
Have not noticed a lot of rust under the coating, yet
Appreciate all the feedback. Bit confusing at times as some have good luck others don't with formula 1. Maybe we are all making a different mistake.
