Well, it really kind of sucks, but in addition to the military issued bug juice and Skinsosoft, I used to suck on match heads to increase the sulfur in my blood. Ticks wouldn't keep latched on, and mosquitoes would avoid biting you too. Don't know I'd recommend it unless you're going into the deepest darkest though...You might consider wearing some Coolmax or Nike Dri-fit leggings to cover your exposed skin.... and putting some reppellant on them too.
