Montana is mosquito paradise. I never saw more or larger biting insects. We also endured hordes of chiggers, deer and horse flies. If you are not averse to using DEET, this product may be for you. It is 34.34% DEET and available in a cream lotion, like a sunscreen. The benefit of this lotion is that it provides an honest 12 hours of protection and is splash and sweat resistant! I used it on the top of my hands and neck mostly. Even when my hands were wet from the frequent splashing of water, the mosquitoes kept away. If you are worried about the DEET smell getting on your flies or rig, simply apply the cream with a paper towel. This is truly a great product, if you don't mind the risks associated with DEET. It is costly at $9 for 2oz., but worth the cost. Give it a try.
