Midges in the Scottish Highlands are so sensitive to wind that the act of hiking itself creates enough of a breeze to prevent them from biting. As I found out first-hand this week: just keep walking. [Additional: Avon Skin-so-Soft seems to prevent midges from surviving a landing, but I didn't find anything to beat larger clegs/horseflies except a good slapping - they will bite through clothing]
