We used to get the Bens 100s
it was 99.95% pure deet. Burn the legs right off the little fkrs.
The CF issue stuff is 68.5% and
Canadian Commercially available limit is 30% Deet.
The High octane stuff was good to blend with Suntan lotion.
My Dad will swear by the Watkins and 20 years in the woods will learn you a couple thangs.
Still Citronella and dryer sheets and the Permetherine all good best solution to the little flying biting bastards....
