Anyone out there have experience with trying to mask food smells? I have noticed in areas where I have camped very near to civilization that a tiny bit of tea tree and/or cedarwood oil can help keep insects and small pests away from food, possibly by masking the smell or making it unappealing. I place it inside a plastic bag lining a stuff sack, but not in contact with food of course. I have never tried this in deep wilderness, and always hang or otherwise safely store food regardless. I'm wondering if anyone has tried this because I'd like to avoid foolishly drawing in animals with a half-baked idea that hasn't been thoroughly researched. I know nothing can perfectly prevent animals from finding food, it's the core of their survival, but I'd love to hear of anything that might reduce the chances of a faint smell(every food bag lets some smell out) from drawing in animals. I am more interested in repelling mice and other rodents anyway, since a bear will either tear down a bear bag, or fail to get it. Mice and other rodents can climb right in and leave me none the wiser till morning. Thoughts?
