Here's a 100% DEET-free bug spray called Herbal Armor made by All Terrain. It was clinically tested at the University of Guelph in Ontario, Canada to be 100% effective at repelling bugs for 2 hours, 95.8% effective for 3 hours, and 77.1% effective for 4 hours. So it's recommended that you apply it every 2-3 hours to stay fully protected against those buggers.
It's made of 6 essential oils recognized by the EPA as bug repellents including Citronella, Soybean, Peppermint, Cedar, Lemongrass, and Geranium. It's water and sweat resistant, and it works! (I speak from experience.)
Even though it has Citronella Oil in it, the other oils mixed in there give it this lovely lemony scent. It's safe to spray on your skin and on your clothes. If you want to protect your face, just spritz some on your hands and rub them on your face, to avoid getting it in your eyes.
This stuff is safe for your skin, won't damage your clothes, and protects you from mosquitoes, ticks, gnats, flies, ants, black flies and other pesky insects, so bugs beware!
