i just happened to have a stock of alcohol on hand (wink) and found that it repeals mossies but only for a half hour or so...
I was on the beach this weekend after sundown - the recent wet weather has increased the numbers of mosquitos a lot and I felt being bitten many times on my legs and saw bumps already forming. My legs started to itch badly. Twice I spayed those lumps with ethyl alcohol and then my whole legs. I never experienced any itching again and the bumps diminished in size rapidly.
