I like to use coon urine but I think fox urine works well too. I spray it on my boots and on the backside of the tree I’m in. The logic behind these types of cover scents is that fox and raccoon are meat eaters but they aren’t a threat to deer. So, any predator smell that might leak out of your scent control program will mix with the scent of the urine and, hopefully, will not be picked out by the deer as being a threat. It’s along the same lines as the folklore that we’ve all heard that the Indians used to not eat meat for days before a hunt to minimize their predator odor. I don’t think it’s a good idea to use an attractant as a cover scent. Acorn, vanilla, etc. are more lures than cover scents. I think you want a scent that blends in with the forest, not one that causes a deer to focus in on you or your trail. Scents like coon and fox urines, Fall Essence, pine, cedar, earth, etc. are better choices for cover scents.

Of course, being as scent free as possible is the first step. No cover scent will make up for a poor scent control program but I disagree with the guys that say a good scent control program with a cover scent is somehow worse than a good scent control program without a cover scent. Just MO.
