Natural/Plant Based Repellants

It is important to remember that essential oils, while derived from plants that grow naturally, are chemicals too. Some are potentially hazardous if ingested or applied over wounds, cuts, irritated skin or mucus membranes, such as the eyes.

Eucalyptus Oil p-menthane 3,8-diol (PMD)

This plant based repellant uses the oil extract from Eucalyptus (E. citriodora) trees as its active ingredient. This has been the primary repellant used in China for 20+ years. PMD has been identified as the compound that provides the strongest insect protection in this plant. In 2000, the US EPA registered this compound for use. Although PMD, the active ingredient in Quwenling has been China's repellant of choice, products containing PMD are relatively new to the U.S. market. There are special warning labels on products containing PMD advising users not to get the product in their eyes and to avoid spraying directly on or near the face. Users are also advised not to use PMD on the faces or hands of small children. PMD is not to be used on children younger than three years of age.

Citronella Oil

Approved and registered for use in 1948 by the EPA as a repellant, Citronella Oil is derived from Citronella grass (Cymbopogon nardus). There have been no reports of serious adverse reaction to dermal applications at label rates. Testing has shown that it is moderately effective and also short lasting when applied to the skin. Candles and space sprays are largely ineffective as repellants.

Currently the Centers for Disease Control and Prevention recognize and recommend the use of DEET, Picaridin and Oil of Lemon Eucalyptus as effective in repelling mosquitoes and reducing the chances of contracting West Nile Virus and other mosquito-borne diseases.
