Beaver oil sacs

I have a gallon of beaver oil sacs, frozen fresh. What can I do with then to make a bait/lure for K9s?

I would post this in the lure and bait maker's forum. Will get seen by the right folks.

A lot of the coyote and cat lure makers use oil sacs.

If you want to use them yourself just strip out most of the oil then leave the empty sacs to taint a bit. Then freeze them for the up coming season.
Tainted oil sacs are a great attractor.

Then you may be able to sell the oil.

If you decide not to make Anything.you can sell them. Ours go for 3-5 dollars a pound

trade them to a lure maker for already made lure. That's what I do, anyhow. And add the castors, too. Most lure makers give you a discounted price on traded product.
