James Valley Scent Company Scrape Gel. Scrape Gel enhances breeding scrapes during the pre and full rut periods. It contains doe internal glands, "in-season" estrous urine, domestic and foreign musks, doe secretions and calling agnets that "trigger" breeding behavior in whitetail bucks. James Valley Scrape Gel also works as a great trail attractant for making scent trails. Gel form is the way to go when using scents at breeding or mock scrapes. Evaporation is minimal. The gel scent lasts much longer. Use 3-4 weeks prior to the peak of the rut in your area. James Valley Scent Company Scrape Gel.
