Greetings from Borneo rainforest, 23% Icaridin did the trick, no bites. Except on the areas that weren't sufficiently protected. Yes, this is also nasty stuff, it burns ons skin when you apply it, even if it's on top of sunscreen. Icaridin doesn't melt plastics like DEET does. I was surprised how well it protected me, even if I was sweating like a monkey. Btw, we were only ones on that hiking trip who used this stuff, most used citronella, because they didn't like these chemicals. Also some areas ban these chemicals for environmental reasons.
