just learning;
Be sure and get those tips from Asa. They will help you. Also as mentioned, a video will also help.
Here is one thing I think anyone who is trying to coyote trapping should remember!!!! DON'T MAKE IT ANY HARDER THAN IT IS! No doubt, the coyote is the most cunning of the canines you will trap, he still can't count to one, so don't screw yourself up by making it to complicated and hard. I have caught my share of coyotes and for the first couple of years (early 70's) I made it to hard on myself. I thought there was about 100 different steps I had to go through just to get a trap in the ground that would take a coyote. So I would take 20 minutes to get a trap in the ground. That is nonsense! Now I punch out a bed, set and gone in under 5.
1. Habits: Learn the habits of coyotes and you can't get it all in books or videos. You have to be out there with him. Learning what makes him tick. Not just where he travels, but WHY he travels that route instead of another. When you learn to "think" like him, then he isn't so hard to catch. Remember that a coyote (or any other animal) CANNOT go beyond his nature. His sole instinct is his preservation and survival. He cannot "think" beyond that. It just can't happen! Everything he does is directly linked to the perpetuation of his species. Even his "play" is linked to his survival. So if you know his nature, and his habits being a part of that nature, then you have an advantage over him.
2. Locations: Some of his locations have been mentioned above. Others on the places you are trapping will become evident. You may find his tracks or sign and that may be a good location to set. HOWEVER, I DON'T TRAP TRACK! While I do pay attention to tracks that I see, I do not set specifically because of a track being there. What if it is a transient coyote just passing through and looking for a new home? He may never come back. A good 80% of my sets will not be set directly as a result from seeing his tracks. I set where I know he will be without ever seeing a track. Believe it or not, I can sit here at my computer desk with a topographical map of your trapping ground and pick his locations without setting foot on where you are trapping. But that doesn't make me special-most any good coyote man can do the same. That is something that you will have to work at by staying out there with him and getting a lot of experience under your belt. "High Rollers" / "Long liners" often use this technique when going into new and unknown areas. If the terrain makes it possible, these same men can spot a set location 1/4 to 1/2 mile away or further. Scouting an area is good but "going in cold turkey" can be just as productive if you know what to look for and "home in" on a location "just because he will be there". Once you have mastered Step #1 Habits) above, then you can get his location with no problems. Many, many times, I have seen a location from a distance that I had never been to before and go there and find scat, tracks, etc. That comes from the experience of knowing his habits. That won't come to you in a week or even a season probably. That is why I say get out there with him and not just rely on books and videos. Books and videos will definitely help and I have a number of them. But NOTHING can make you a coyote trapper if you don't get out there and do it and learn him in the field.
Yes, it would take volumes of this forum to "teach" coyote trapping to its fullest. Set construction, lures, cleanliness, etc. all play a part. Just to much to post all at once. Stay here with the forum and I bet you will get a lot of answers that will help you.
