Statement from The New England Journal of Medicine

Eucalyptus repels insects -
“Thousands of plants have been tested as potential botanical sources of insect repellent. Most plant-based insect repellents currently on the market contain essential oils from one or more of the following plants: citronella, cedar, eucalyptus, peppermint, lemon grass, geranium, and soybean. Of the products we tested, the soybean-oil-based repellent was able to protect from mosquito bites for about 1.5 hours. All other botanical repellents that we tested in our initial studies, regardless of their active ingredients and formulations, gave very short-lived protection, ranging from a mean of about 3 to 20 minutes. Preliminary studies suggest that the oil-of-eucalyptus products will confer longer-lasting protection than other available plant-based repellents."
