I don't think it is the way I set the trap that will make the difference.
I really think it is the trigger that I need to find that will get them to move in.
The right gland lure but most likely not in a tight space like a pot, or large bait. My wolverine are much the same way. They ignore anything that isn't substantial. They walk right by my marten sets. At least the last few years. But big baits like a beaver will hold the interest of both. When ever I put out a beaver for bait. The marten are on it. But they will walk right by a small piece time and time again. I can't figure. I have to transport my bait quite a ways. Along with camp etc. Time to change my stategies.
I have seen multiple marten hold up on a beaver. I am hoping that by working less sets with larger baits and more traps at a set will bring more marten home with me.
Castor I set so few with legholds I don't remember exactly. I think I took the tag end of the wire that was left on the trap chain and gave a hook through a fence staple. Something that with a struggle would give way.
I found a great way to make a ground cubby release for a conibear and tipup.
By cutting a tree that the conibear will just fit over when unset will hold very firmly when set. I just poke the tree into the snow and pack firmly. Attach conibear and then build my cubby. This made a difference but still was not as consistent as I would like.
I built the cubbies out of black spruce tree tips. One side shaved down. They worked quite well.
Something that I did last year. As mentioned above was to keep a can of spray adhesive in my coat. At a set I would spray the tree and apply feathers. Same inside the pot. How much eye appeal do you need? The method worked really well in theory. Marten were indifferent..
