One big downside to most repellant sprays is that the mosquito's aren't the only things that can smell. Deer can pick up the scent, too. I like to expose my clothing to smoke. Smoke is a natural scent that doesn't alarm deer. I spray my face, arms, and legs with 29% Deet, then add my layers of clothing. Leafy-wear is my outer-most layer, so that is the layer I cover with the smoke scent.
