I also believe that human scent a factor in someplace but not in others. You go down to South Texas near the border where the coyotes are thick as flies and you will catch them easy. BUT go to West Texas in sheep country. And you better come correct. Drop cloth clean gloves and traps are a must for sheep killing coyotes
And the Crimson Tide was picked to win the SEC
I never used a drop cloth unless I was kneeling in pure mud or very wet conditions.
If it is too wet, I've used a mud flap from a truck, but that's a specif circumstance.
I normally just kneel on the ground, with one or both knees.
I don't have scent glands on my knees, after all, and when you are tall, it is much easier than squatting, especially as you get older.
I have killed coyotes year-round that kill calves, poultry, and even yes, even sheep.
I'm the least correct person you'll likely meet and I still get paid.
Coyotes aren't ( for the most part ) spooked by human scent at a set.
Calling ? Yes
When they can't see you ? Yes
But not at a trap or snare location. . .( again ) at least for the most part.
Unless you're oversaturating an area, by being there too much, then yes, you'll see where the coyotes will move out.
What I meant was, for the most part, the human scent does not spook a coyote at a set.
Set the trap, get in, get out and leave it alone.
That's killed a lot of coyotes for me and most trappers I know.
