I've been using picaridin for years....Cutter Advanced. Actually got the tip off this board. Works great on Mosquitos....not so good for Ticks though.

Was just reading this article today...

In Consumer Reports’ entire history of testing bug sprays, harsh chemicals like N, N-diethyl-meta-toluamide, commonly known as deet, have always come out on top. But for the first time, safer, gentler products were more effective.

The winning products used picaridin and oil of lemon eucalyptus as the active ingredients. Both are chemically synthesized ingredients but more similar to natural compounds than deet; they also come with fewer side effects. Best in show were Sawyer Fisherman’s Formula, which held mosquitoes and ticks at bay for eight hours, and Repel Lemon Eucalyptus, which protected against ticks for eight hours and mosquitoes for seven hours.

Products starring plant oils like citronella, lemongrass and rosemary didn’t work. Candles and wristbands didn’t work, either.

“Look first for products with 20 percent picaridin or 30 percent oil of lemon eucalyptus,” the report said. “We think they’re safer than those with deet.” If deet is your only option, aim for a concentration of about 15 percent, which even outperformed the product with 25 percent. In concentrations more than 30 percent, deet might be dangerous, the authors conclude.
