If you are a trapper that needs a consistant lure for M-44's, grub stakes, chew sticks or dirt holes, this is the one. I have sold a lot of this lure to trappers that rely on it for their job. It comes through every time. I don't how many of thousands of coyotes it has killed over the years, but I know it has made an impact. I always have a bottle of this one with me on my line.
