just a thought if you are camping and there are lots of midgees that can get quite anoying there is a product by Avon cosmetics called 'skin so soft' and is apparently the best repellant someone told my dad about this and he used to use it when working in midgee territory. It was not designed as a repellant but is apparently better than other things that are.

ps I'm afraid i don't know Avon's policy on animal testing.
