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.

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.

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 downwind 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.

Then there are weird muskrats. In the Klamath Basin, in southern Oregon east of the Cascades, muskrats were not native to the landscape. They were introduced first in the 1920's, and the first introductions were of course by a couple of enterprising ranchers. The original stocks came from Minto Flats area outside of Fairbanks! They were valued for their very dark pelts. However, they were pretty small compared to their Louisiana cousins, and as such, another batch was brought in from there.
When the fur boom went bust, like so many other fur farms that went under, the rats were turned loose.
The Basin is perfect habitat for the rats and they flourished, to the chagrin of some here that rely on ditches and dikes to manipulate the water here.
Enter me, and a biologist that steered me to a fellow with an 800 acre rat problem. This is only the 2nd year I have trapped the property, and while I try to at least put a dent in his problems, he is adjacent to an even bigger, (roughly 1 mile by 12 mile), problem. A perfectly un-disturbed rat marsh heaven that is completely un-molested.
These three rats were taken the same day within 50 yards of each other.
