Ah, I see you ordered 40% Deet. Keep it for use on clothes (cotton or wool) but buy some 100% for use on skin. Oh, almost forgot! Start taking B vitamins about a month before you leave, B-6 is the key one. Don't eat bananas or potatoes for a week of two before you go. Mosquitos target, potassium, carbon dioxide, and body heat...and probably a million other things ;-) The B-6 is widely used in the Alaskan bush. Double or triple the dose on the vitamin bottle. Your pee will be bright yellow but you'll get fewer bites. Dark colors are also said to attract mosquitoes, like I said a million things.
