That's nice; get back to me when you find something portable, ie something good for hiking.
The point of the article is they can't fly faster than 2 mph or so. Simply move faster than 2 MPH. I've ridden my bicycle thru swamps and not gotten bit.
I also hike and between walking and a bit of wind there is not much problem as long as I don't stop.
A bug in the eye still hurts... wear sunglasses.
I haven't tried them.
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]
