I had mixed results here in Michigan. When I put it on the ground, the deer would hit the area if that was the only food present at that feeder site. However, if there was corn or other type of feed avialable they would not hit the buck grub. I also tried using it as a topping over the corn in my feeder. Since the deer ate the corn anyways, it was difficult to see if the Buck Grub had a true effect. When the feeder would go off, you could see Buck Grub Dust going everywhere. It seems to work best when concentrated and not in my feeder. I just could not see the benefit when other feeds, i.e. corn, was also available at the site.
