DEET: The Gold Standard Mosquito Repellent
DEET is considered the gold standard of mosquito repellents, providing several hours of protection when applied to the skin. It was developed in the 1940s and has been found to be safe for use by pregnant women and children over two months old. DEET can damage plastics and synthetic materials, so caution is advised. Although it is absorbed into the bloodstream, it is cleared from the body within a few hours with minimal adverse effects when used correctly.
Alternatives to DEET: Picaridin and Lemon Eucalyptus
While DEET has been the most effective mosquito repellent, alternatives like picaridin and lemon eucalyptus have emerged. Picaridin has shown similar efficacy to DEET with fewer adverse effects and a more pleasant odor. Lemon eucalyptus, recommended by the CDC, has been effective in repelling mosquitoes and ticks for up to seven hours. Other natural repellents and essential oils have shown limited effectiveness and are not recommended.
