- NAF Deet Fly Spray 750ml

This totally new formula from NAF contains simply Deet, which is an extensively researched and proven fly repellent, and fully HSE approved. NAF have not mixed the Deet with any other insect repelling ingredients as it is most effective when used alone. Its included in the formula at a level of 19.6, which NAF believe makes it the strongest available on the market, whilst falling within the HSE guidelines. NAF Off Deet also comes in the option of a gel. NAF have made the concentration of Deet in the Gel weaker than in the spray as it is designed for use around the eyes and other sensitive areas.
