Yes it would have a effect on efficiency. To reduce the effect do as I said in my previous
post. But, mark your snares with a orange florescent painted clothes pin attached to a limb/whatever above or near the snare so you can locate it at a greater distance.
Walking thru the same route each check should make the coyotes think it's a normal routine and of no significant threat.

Some very interesting information being shared here. Has anyone had succes into a frozen cattail marsh, matting down an area to start a bait site and then hung cable on the natural openings / funnel points that are present?

I do a fair amount of snaring in just that senerio. You don't have to mat down to big of an area, the coyotes will do that for you once they find it. Set on trails they make but don't set snares too close. You can set multiple snares on each trail.

That's how i started snaring.I had leased a large marsh I allowed duck hunting but I was after the rats. The duck hunters beat down many trails as they accessed open water. Once the marsh froze I dumped all my saved rat carcasses on the ice or up on the rat huts. Then I started hanging snares In those trails. The fox were already using those trails checking out the rat huts. The bait just made things better.

I would drill a hole in the ice and drop a dead man through the hole to anchor the snare.

This scenario works great. I have a spot just like this. Tall cat tails and reed canary. What's nice there are a few beaver runs running through this and am able to put bait in and setup the trails before the coyote move in. There are some years I don't even need to put bait out.

Thanks.for.the replies!
