I have heard a lot of people talking about cover scent. You go to the local store and there is tons of the stuff. From fresh earth to acorn spray. All these scents are pricey. Whether you get the "biscuits" or the spray. Something we started doing in our lease several years ago has benefited us quite well and may help you also. We started using our surroundings to make our cover scent.
We have lots of pine trees in parts of our lease. So when we are hunting that area, we store our clothes with bags of pine needles. Just use a plastic bag, poke a few holes in the bags and after about 24 hours, your clothes smell like the woods you are hunting. We have quite a bit of hard woods in our lease also. We like to take acorns and pine needles, boil them for a bit, strain, and then bottle. This works really well as a spray cover scent.
So wherever you are hunting, use your surroundings to make your cover scent. If you're using something to cover your scent that is not natural in your habitat, then it's just another scent that you are adding. Be sure to be as scent free as possible and then smell like your surroundings. Hope this helps.
