It’s easy to say you’ll never use DEET, that is until you come down to South Carolina. My home state boasts mosquitoes that rival your house pet in size and stature. But still, many fear the toxicity of DEET and try to avoid it even with those mini-monsters landing on you noon and night. According to the CDC, lemon eucalyptus oil could be a much safer and more natural weapon. The CDC confirmed that lemon eucalyptus oil can be as effective as DEET in repelling mosquitoes, a story reported on Mattermore:

    Oil of lemon eucalyptus [active ingredient: p-menthane 3,8-diol (PMD)], a plant- based repellent, is also registered with EPA. In two recent scientific publications, when oil of lemon eucalyptus was tested against mosquitoes found in the US it provided protection similar to repellents with low concentrations of DEET

Mattermore reports that until recently, DEET was the only repellent recommended by the CDC, and approved for individual use by the Environmental Protection Agency (EPA). Oil of lemon eucalyptus is plant-based repellent oil made from leaves of Eucalyptus citriodora.
