Beat the Bite, Naturally
All repellents, chemical and natural, camouflage your humanness by messing with insects' olfactory senses. Going natural simply requires a shift in thinking, says Steven Kolmes, a biology professor at the University of Portland in Oregon. "If you want a product that's safe, it's going to be less convenient and you'll need to reapply it every two hours," he points out. All bug repellents should be tested first on a small patch of skin to avoid allergic reactions. Also, experiment with a variety of combinations and brands because everybody's chemical physiology is different.
In 2002, The New England Journal of Medicine compared several repellents. Oil of lemon eucalyptus tested similarly to low-level DEET, but is safer and lasts two hours. Soybean oil offers 94 minutes of protection with no known risks. Citronella protected for 20 minutes.
In other research on natural bug repellents, scientists from Taiwan found that cinnamon oil--an environmentally friendly pesticide--was actually more effective than DEET at killing mosquito larvae. To use any essential oil topically as an insect repellent, always dilute by mixing 1/4 tsp. of essential oil ...
