The success of remakes after a catch shows how the overwhelming scent from a previous catch can be attractive for some reason. I have always wondered if there was a way to reproduce that scenario from the start as a cover scent. I can’t remember which famous trapper’s directions I was reading long ago, but he used a ton of urine on the sets. He even coated his hands with urine as a cover scent for any contamination by his own scent. EJ Dailey maybe? While I have not put urine on my hands, or on a bare trap, I have misted a whole set with a few sprays of urine as a cover scent at dirt holes with louder bait. I don’t keep good enough records or control other variables to look at the stats over the long run. I like to do this at sets I make when it’s warm out.

Again, anecdotal evidence is all I have. Once a coyote gets caught, I remake the set as best I can and usually put in another new set nearby. The remake is definitely more attractive than the newer set, at least in the next couple days in my experience.
