Undertaker is a 100% waterproof scrape starter made from real dirt that is infused with Apparition Scents. Use Undertaker to establish mock scraper or enhance an existing scrape to keep bucks returning daily. It will not wash away due to weather and will maintain its lethal attractiveness for 1-2 months depending on weather conditions. We have eliminated the need for messy unreliable scent drippers and educating deer with human interaction.
