This product was also specially manufactured per my request. It is a combination of different vegetable essences and has a long lasting odor that will lure groundhogs during the late summer and fall until the time in which they go into hibernation. (in northern climates) I first put this product in the paste form, but found it to be about 30% more effective in liquid. This lure is also very attractive to the striped skunk in mid to late summer. Many trappers across the country have chosen this as their all around lure for all species.
