I've been using the fresh earth scent wafers by HS Scents for years. I always use scent free laundry detergent on all my hunting clothes and then I store them in a plastic tote year round with 1 scent wafer. I've had deer all around me numerous times. I believe they work and I'll continue to use them. I had 3 bow kills this season and all were within 10 yards. Ya just can't argue with success.
