Backpacker Magazine did a test on mosiquito repelants. They did the arms in a cage full of mosquitos with the different products. The products that faired the best were lemon eucalyptus, not the deet based. Althought the Deet did pretty well.

We use the Repel lemon eucalyptus instead of deet when we camp and hike. It worked better then the deet based sprays and it doesn't have deet in it. The smell is strong but dissipates pretty fast. Never got a mosquito bite with the stuff on.
We have used the Ben's with 30% Deet, it works pretty well as well.

Working on some Frozen Summit. Cooper seems to be ok, Caya is loving the extra meals, hip is feeling fine, and the weather is awesome. Loving life right now.
