I'm a 25% DEET minimum man myself. The 90 something percent stuff is even better, but it really melts plastic.

I can't use it when carrying camera gear except on my legs, but the DEET really does work. However, I've found that it seems less effective in certain areas, particularly in the woods, especially pine forest, compared to out in the open. Maybe it works best with a little breeze?
The off wipes are a cool idea, but work less than the 25% DEET spray, which is the bare minimum in my mind. Sometimes I want to put on the dog's Frontline/Advantix, and let the suckers bite me, only to have them die when they do.

As for the Apple Cider Vinegar, I've heard that too, and I imagine that it has to have some effect, because I can smell other things on myself days after I eat them, like onions and garlic, but I have a freakish sense of smell. I won't be using this rememdy, however, because even with a 40mg Zegerid (PPI acid reducer) a day and a bottle of Tums a week, I'm still having stomach pains despite being medicated for this "gastritis w/GERD" for nearly a year. I think my doctor's aren't helping me enough...
