Sawyer Products SP543 Picaridin Insect Repellent, 3-Ounce, Pump Spray

In this 20% formulation (the strongest available in US) picaridin seems almost as good as much higher concentrations of DEET in repelling our ravenous Minnesota mosquitoes. It might not last quite as long as the strongest DEET products. However, the huge advantage of picaridin is that it doesn't dissolve plastic products like cameras, binoculars, camping gear, etc. I can apply it and not worry about causing damage to my gear. I gave away my bottles of DEET, and I'll never go back to it. This particular Sawyer product has almost no scent when dry. I've also tried another company's 20% picaridin product, but it was so perfumy that my wife refused to ride in the car with me when I used it. I threw it out! Now I'll only buy 20% picaridin and only in unscented products. But I wish that Sawyer had a more predictable and consistent sprayer.

This strength of Picaridin based insect repellant is nearly impossible to find. (Major drug store had some, but the % of Picaridin was way too low.) Son has gone on mission trip to Panama, and this is the mosquito repellant his doctor told him to get when he went to get his shots for the trip, for Malaria and Dengue/Yellow Fever prevention. The bonuses are that it smells nice, and it does not "eat" your clothes, flip flops, etc - and I am assuming wouldn't affect nail polish the way DEET does. It's in a pump spray bottle, which is much less cumbersome than a big aerosol - and you know how much is in there, which is nice. Hint: He flew from Atlanta to Panama, and arrived at night, which is the worst time. The bottles are too big to clear TSA, so we dispensed some into a travel sized pump bottle and checked the rest in his luggage. He was able to spray it on before he ventured out from the airport.
