Snow is a great learning tool. I rarely have any snow down here in Central Texas. Most of my trapping is like trapping on the moon. All rock and no soil. I’m always envious of guys who have snow.
A lot of guys crowd the hole with their trap. That it’s fine if you have what the coyote wants. But take a look at where most of the traps are concentrated. With a dirt hole set, the tracks are farther back - 18 inches or more sometimes.
It takes some confidence to set a trap way back there when you think you might miss a coyote coming in from the side. I rarely set whole set down here because it’s hard to dig a hole in our ground. But when I do, I’ll put one set crowding the hole on an earth anchor. I’ll set another trap back 18 inches down wind on a drag.
I’ve had some luck catching a coyote on the drag and having one stuck at the hole. I have more luck catching a single coyote on the drag 18-24 inches back.
With flat sets, crowding the attractant is more important. The set is more subtle and natural. A coyote has no fear of a single piece of poop on a road, so he walks right up to it. So there is no need for your trap to be set back. He won’t hesitate as much. Down here, even a T-bone driven down to the ground can make a coyote back off a ways. So I set my trap accordingly.
All this is just my experience. Let your experience guide you. Thanks for sharing. Maybe try a flat set before a snow and see where the tracks concentrate.
I'm no great trapper, but I'll give my opinion (everyone has one and most are worth about what you pay for them) crowding the hole or attractant makes it much easier to direct and/or guess exactly where he is going to put his foot. This is a more productive method if you are trapping unwary critters. On the other hand if you are dealing with wary critters they will often hesitate to approach closely, so you need to place your trap further back to snag them. To make it even more difficult, they are already wary and anything but the most subtle guiding will often cause them to avoid the set entirely. This is where being able to think like your quarry and know where he is going to place his foot comes into play. And even the best are still going to have misses. But they'll have less refusals, also.
Know your quarry, and your goals, and set accordingly. If you are going for numbers and have a bunch of dumb, uneducated critters. You are better off putting in a number of sets, crowding the attractant and using blocking to direct their feet. You will really cut down on your misses. But if you are dealing with primarily educated animals or are needing to catch a particular stock killer, etc., you are going to get way too many refusals with that method and subtle, trap placed back and little to no guiding will give you the best results.
