No you can notcover or mask your scent. Just ask the officers who use drug sniffing dogs. Drug smugglers use all kind of things to cover the scent but fail. The dogs can even smell drugs put in gasoline. Dogs are also used to find a drowning victim under water. The molecule do not mix or get covered up. A deer can smell one part per million. If cover scent worked then a deer would never be able to pick up on the scent of another deer or person on the ground. The smell of the dirt and grass would cover up the very small amount of scent left on the ground by the other deer or person. So don't think a couple of squirts of scent can overpower a deers nose.
