I know alot of trappers use cotton, sheep's wool etc., to place their lure on and shove it down a dirt hole. A couple of years ago I experimented using lure holders and not. It is kinda of hard to have a control group, but I found that by pouring the lure directly into the hole, the animal worked the set harder and longer. One thing they can not do is grab your lure holder and run. I just wonder what the rest of you think about this subject.
