I know some guys who used the anise and beaver castor scented bombs this spring to spruce their baits up when on stand, they claim they worked. Personally I have used Anise and 12 miles of dead fish bear sense sticks to spruce up baits in the past. Like anything you need to be in the right place first off, if a bear can't smell it or doesn't feel comfortable in the surroundings to come in, they won't work very well. FYI, if you do use the beaver castor or 12 mile of dead fish look out the smell can be pretty intense[8D].

Good luck
