What smell do gnats hate?
Frankly, you can spray or glob dozens of so-called repellents on your skin to hopefully keep gnats from landing on you. However, "blocking" gnats from landing is not "repelling" them! If a swarm of gnats have located you, it is only a matter of time before they discover a part of your body that you have missed!
Today, science has proven that gnats, mosquitoes, black flies, no see um, chiggers, minges, deer flies, and ticks are all attracted to one thing......the carbon dioxide flume that all humans and animals exhale when they breathe! (Research the Research) And, science has also proven that certain fragrances will interfere with an insect's ability to detect carbon dioxide. Go figure!
"If they cannot find you, they cannot bite you!" Says Ole Time Woodsman Fly Dope!
Back in 1910, when fly fisherman Obie Sherer was being chased from his favorite fishing hole in Maine by a hungry horde of black flies that he noticed a local Native American sitting peaceably by the stream without a biting insect in sight! Now this was way before chemical bug repellents became in vogue. Deet was not patented until 1946.
Somewhere in his mind, either by chance or his love of fly fishing, Obie reckoned that a particular blend of natural fragrances from living in the woods could protect a person from biting insects! Using a base formula that hunters in the day applied to themselves to camouflage their human scent, Obie developed a product that he called Ole Time Woodsman Fly Dope. Soon thereafter a logging foreman saw Obie peaceably fishing in his favorite spot. A handshake contract was made and the first commercial batch of Fly Dope was sold.
