The Ole Time Woodsman Fly Dope challenge to chemical mosquito "repellents"!
For over 100 years, Ole Time Woodsman Fly Dope's formula has kept mosquitoes, black flies, noseeums, and now ticks at bay because it interrupts a biting insect's ability to sense the carbon dioxide that humans and animals exhale every time that we breath.
Chemical repellents rely upon a person applying or spraying on globs of Deet et al, to prevent biting insects from landing on you or your pet without hair. If you question this, please do the research about "landing" versus "biting" that is published by the chemical insect repellent manufacturers.
Ole Time Woodsman Fly Dope's formula states, "if they cannot find you, they cannot bite you!"
Ole Time Woodsman Fly Dope should be applied "before" you go out of doors. A couple of drops on a hat brim, some on a bandana, and at few drops on your shoe laces.
As for chemical "repellents", just follow their instructions. Rub, glob, spray, whatever.
The challenge: How many biting insects are around you when you are trying to do an outside activity during "bug" season?
