哪种驱蚊产品好？
答：CDC推荐使用经过科学实验包含有效成分并且被美国环境保护协会（EPA）注册认可的皮肤或衣服上使用的产品。当EPA注册一种产品的时候，他们会评价该产品的疗效以及其对人和环境的潜在影响。EPA注册意味着EPA不希望，一个产品根据其标签说明使用的时候，对人体健康或者环境带来不合理的有害结果。
在EPA注册的有效成分中，CDC相信两种在同行评审和科学文献中 Publications已经表现出很高的疗效。包含这些充分的产品通常提供比其他产品更长时间的保护：
• 驱蚊露DEET (N,N-diethyl-m-toluamide)N，N-二乙基-3-甲基苯甲
• Picaridin (KBR 3023)
• Picaridin (KBR 3023)
柠檬桉油是一种植物驱蚊剂，同样也是EPA注册的，最近的文献指出和，其提供和低浓度的deet类似的驱蚊效果
Which mosquito repellents work best?
A. CDC recommends using products that have been shown to work in scientific trials and that contain active ingredients which have been registered with the US Environmental Protection Agency (EPA) for use as insect repellents on skin or clothing. When EPA registers a repellent, they evaluate the product for efficacy and potential effects on human beings and the environment. EPA registration means that EPA does not expect a product, when used according to the instructions on the label, to cause unreasonable adverse effects to human health or the environment.
Of the active ingredients registered with the EPA, CDC believes that two have demonstrated a higher degree of efficacy in the peer-reviewed, scientific literature (See Publications page.). Products containing these active ingredients typically provide longer-lasting protection than others:

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.
