Testing and Recommendations
In 2000 the World Health Organization proclaimed that, due to its safety, effectiveness and cosmetic properties, Picaridin was their recommended product for repelling the mosquitos that carry Malaria. They noted that under some circumstances it was more effective than DEET.
Dermatological testing has shown that Picaridin is almost odorless and not irritating to the skin (a major drawback to DEET insect repellents). The Jan-Feb 2004 issue of the Journal of Drugs in Dermatology declared it to be "as effective and less irritating than diethyl toluamide (DEET)".
In 2005 the US Centers for Disease Control revised it's mosquito repellent recommendations to include Picaridin in their list of products which are effective in preventing against the transmission of West Nile Disease
. Also added to the list was a naturally-derived product, Oil of Lemon Eucalyptus. Products containing oil of lemon eucalyptus
offer mosquito protection comparable to low-concentration DEET
Picaridin has also has been tested for effects on various household substances and has been shown to cause no major damage to plastics, sealents, plastic coatings or other synthetics.
