Could someone post a descrption of how those funnel traps are made?
Do they have some kind of door, or??
I'm particularly interested in otter sized traps.
Use heavy chicken wire and make the funnel opening about as big as your fist for otter, a little smaller for mink and rats. Wire the funnel on secure otter can squeeze through any small opening and can literally wreak a trap. I use cage clips or wire to fasten them. I used to stretch the funnel shape by pulling the wire mesh down on a nail evenly all around.
Set in tiny creeks with thin ice. Pile brush on trap so the otter/mink will not see it and hunt for fish in the brush and makes them dive under. The red willow tips are commonly used to hide the funnel. Pile dead grass, snow on top of the brush.
Its alot of work to run a line of them allot of shoveling, and big holes to chop open when they freeze.
Most trappers just hung the trap in the bushes and set it again next year. I still have traps hanging out where I used to set, if the prices ever come back. I have one in the shed if you need to see it.
I had a article in the ATA Magazine before the internet days that had some pictures of otter In them. cant remember when that was.
