I have more waterways to trap than I can cover. They are loaded with holes along the edges(from the edges out to 50ft away) that yotes have dug going after voles and such.

I know the general rule is to set on sign. But what's the likelihood of yotes returning to a hole that they or another yote made ?

Would I be better off to make another set , flat set,dirt hole,pipe dream or whatever. Or would it be worthwhile to "remake" a few of the dirt holes that they have made ?

I don't trap coyotes a lot, but if I found where a wolf had been digging I would absolutely blind set in front of that hole

You can set the dugout holes if you would like. I would make a couple of the sets you mentioned just to see what one gets more attention. Seeing how they are going after rodents it probably would not hurt to use a mouse based Bait and make sets based on wind direction .

Answer- They will return.
Trappers make dirtholes to mock a Canine or Rodent digging. Dirtholes are the #1 Canine catcher.
Setting where they are digging and rodents living is a good spot to make 2 to 4 sets.

As has been stated they will return to digging sites and we as trappers try to duplicate a digging sight. Here if I find where coyotes have been digging along waterways it will normally be along a slough or a levee in a crawfish farm. When I find where they have been digging I know that I have to draw them to my set as they can see for a long ways and there are normally tons of dig sites. I approach it like this...

I must get their visual attention. I will take duck down or rabbit fur, and put just enough on the ground and on grass, cane, low bushes, etc, not a lot, just enough to that if they are running along they can’t miss it. This is done last.

I will take a pickax and dig a trench set. I want it to standout from all the other diggings. I try to duplicate an animal digging out an old site. They can see this a mile away and the smell of fresh dirt draws them in. Also, down here I found if you use a deep trench in a dig area a coyote will drop down in the hole and start digging without too much investigation.

Early season I will use bait and a little red fox urine. Down here everything hates red fox and will investigate. If I have some scat it will be used. In late January I switch to coyote or bobcat urine, and I will use just a tiny bit of gland lure. If otters using the area I will use bobcat as they love it and who doesn’t like a piling up otters.

It works down here where I trap, not clue about up north.

Good to read.

I was thinking about setting a couple of the bigger dogs that they've made and making some of my own as well.

But I'm about as far from an expert yote trapper as you can get.

Just wanted to make sure that my pea brain was thinking right about them. As well as get some ideas from you all that have more experience with trapping yotes.

Almost all of the waterways on 6,000 acres are riddled with dogs and they are loaded with holes and mice.

Also thinking about trying a tire set because they would really stand out on the landscape.

If ur going to try a tire set u just as well try cages too.
My opinion is u catch coyotes more so by their nose than there eyes.

When you say cages...what exactly are you talking of

He was being sarcastic.

I would do both.Some new dirtholes yourself and some of theirs.

It's been my experience that if they dig something they do not come back to that bury often because they got what was there. It works better for me in my area to make my own holes with something new in them. I have sandy soil and a lot of voles and moles and lots of digging. Sometimes a flat set gives them something different of there are a lot of holes.
