I've been using the fresh earth spray and scent wafers the past three years. But now I'm thinking about trying to be as scent free as possible. I think the fresh earth scent that is manufactured isn't natural to the deer. If anything I would use dirt and leaves from the spot I'm hunting. I might try some deer dander this year. I'm still up in the air about it. I've heard some good things about it and think it might be worth a try.
