Almost any natural or chemical repellent on the market will protect your covered skin in VARYING degrees for varying lengths of time. Unfortunately, they will not stop the hordes of blood thirsty black flies from tormenting you to death looking for a place to land! The word "repellent" is a misnomer. Black flies or any biting insect for that matter cannot be repelled. But you can "hide" from them!
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!
