Can't add much to that, except I spray my hunting clothes with permitheran, let them dry and watch skeeters land on me and die. One sprayin is good for up to 4-6 washings too. It works on Canadian skeeters and black flys, and if works on those critters it'll work on bout anything else. Vets use it to dip dogs also. Sawyers makes it in a spray, but you can buy it in a bottle at your local version of Tractors Supply.
