Almost any so-called "repellent" when applied to your skin will deter black flies from landing and biting in varying degrees of effectiveness. However, the word "repellent" is a misnomer. Repellents should be called "blockers" because that is all that they do. They do not prevent a horde of blood thirsty black flies from swarming around your head, eyes, and mouth desperately looking for a place that you missed when you applied the latest goop of the day!
The trick is not to block an insect from biting you, buy rather to prevent them from finding you in the first place!
Today, science has proven that 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 Reseach) And, science has also proven that certain formulas of fragrances will interfere with an insect's ability to detect carbon dioxide.
"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.
Ole Time Woodsman Fly Dope. The world's first and best protection against all biting insects!
Just took this camping this weekend, put some on a bandana just like when I was a kid. Not a bite! Thank you!
