Maybe, but I've seen any evidence of it. It does work for squirells. Plenty using it for them. Biggest issue, is that it works well on hedgehogs too.

Yes true, a box with some sort of restriction, may help with regards hedgehogs. They should make a decent squirrel trap, as you said. Up on a tree trunk, away from none target's. Difference between here, and most of the UK is that A, we have a lot more reds, and B, we have a lot more pine marten. Pine marten like peanut butter too. That kind of leaves the trap unsuitable for most parts of this country.

Only way I can see these been usable here for mink, and you reminded me of it, is using it in a wooden box, with a hole in one end. You would have to check regularly though, as the dead mink would remain in the box.

You would, if using a box. The dead mink would block it up. This is why I wouldn't dream of investing in one.

Bait, fish oil maybe? Wouls a mink stick its head in the trap for a bit of oil? Nowhere to put actual solid bait. They have a squirrel bait/liquid, but doubt they'll have a mink bait of any kind. One that would stay fresh for weeks at a time.

If it blocks the hole up, then nothing else can get in, therfore the trap is no better than a fifteen euro Fenn trap. Not worth paying out two hundred or more euro, for something that may end up being absolutely useless.

The fenn wouldn't be at the top of the list for killing quickly, but it's hard bet when it comes to catching imo.

I like timber tunnels. Used as a tunnel, and not a mink box or cubby. Tunnel opened both ends.

Timber tunnels can work very well, especially if you can find a spot where a mink doesn't have many other options, bar go through that tunnel. With either a fenn or conibear in the middle, set in the right location, you will take every mink that runs that bank. No need for lure, bait or anything.

I have a couple of little spots on the rivers I trap, that are perfect for a tunnel set. Ditch that runs right down to the waters edge, with a steep bank on the river. So say, a drop off from the end of the ditch to the water. I will set the tunnel on the ditch, say going through the ditch, and then block off any holes in the ditch around where my tunnel is. Any mink that comes down that bank will use the tunnel, because its the easiest way for him to get through the ditch.

Not a hundred percent sure what mine are. Maybe two foot. Hole seventy to eighty millimeters. Preferably round holes.

Most definitely, and no bait

It would have to be a ledge close to ground level. Easy for a mink to pop onto it when running the bank. I have perfect one on one of my stops. Mink use it regularly. I'd set both sides, if there's a ledge both sides.

Get the odd rat. If the conditions are right, mink will use them a lot. The ledge I set the most, is actually under a dry bridge. Well it's a third bridge that is there to prevent flooding. I've caught mink on that ledge when thre is water underneath it, and even when it's practically dry.

Some good information there on mink and mink sign.

Otters have always been been plentiful here. In the UK the otter population was until recently, not as healthy as ours. In recent years, there has been a major increase in otters there, at the same time, mink numbers have dropped. They say its because of the increase in otters. I don't think they have any hard evidence, that this is the case.

No, the MK6. The MK4 is a bit small for a buck mink

I have a video or two on setting them in tunnels, and in holes in the banks. I can stick them up here if you like

Here's one with a tunnel set up, using a Fenn trap.
