A powerful, curiosity odor that is a proven call lure to the woodchuck when applied to some type of leafy greens for eye appeal. You cannot find a better combination. "Formula One Lure" can also be used alone as a trailing scent. Just apply a few drops of lure to the ground at burrow or den entrance and lead scent trail to cage trap. (Place baited material in the back of the cage in full view.) A great combination when used with Formula One or Formula Two Paste Baits.
