Jameson's Formula Two Woodchuck Paste Bait has an herbal base and is a special blend of natural herbs and select fragrances that 'chucks cannot resist. Like "Formula One" this unique bait has a lush green base that is also a proven staple food of the groundhog. It is excellent bait by itself. Added to it are two proven ingredients that are excellent side odor attractants that can't be matched in calling power.
