I believe as far as the earth scent goes that when it is dry there is not much earth scent so picking up a handfull and putting it in your pocket dosn't get anywhere. The waffers go in my box when I store my hunting duds over the summer. As for the pine sap, it's sticky and I don't like that as it picks up all sorts of other things as well.
If I am hunitng pine I will pick up a pine bough and put it into a plastic bag and lay that at the bottom of my storage container to allow the scent to my camo.
My 2 cents
