I used to have pics of mosquitoes on my permethrin gloves and shirt trying to bite through it while out fly fishing when I lived in northwestern Maine. The only thing I found truly effective against mosquitoes and black flies is DEET. And that stuff is pretty nasty. It once melted one of my fly boxes when the can I had in the same pocket sprayed it down. Can’t be good for you.
