Some of the stories of effectiveness of Avon Skin So Soft came out of Canadian tree planting camps. I believe that oil of Citronella was an ingredient.
Some say that there was gov't pressure to change the formulation to avoid getting tangled up as an unregistered insect repellant. I do not know what transpired, I've been away from the tree planting mob for a long time.
Oil of Citronella works. Even for Black Flies (Simulidae) when you work near moving water which is larval habitat. Dab drops of it along your jacket collar.
I can 100% vouch for that, spent a week roughing it on a caye off Belize. Mate and I were pretty much bathing in skin so soft, sand flies didn’t touch us. A lot of the other lads were eaten alive. It was way more effective than Deet.It's not a soap but Avon's Skin so Soft dry oil spray is supposed to be a very good repellant
