Ive had great results. Once they find your site, they keep coming back. I have one place we threw it down and they have dug a 5 foot wide hole around the place. Allwe do now is throw a new bag down each year.

We have also found that the deer love cattle cake, especially the fawns. We put some down last year around these sites due to the drought and lack of food. They just ate the stuff up.
