防蚊液DIY
準備材料
1.酒精
2.水
3.尤加利精油
4.天竺葵精油
5.茶樹精油
6.薄荷精油
7.100ml噴霧瓶
除了DEET敵避之外，天然植物精油也是防蚊另一種好選擇，根據美國疾病管制署(CDC)的建議，含有檸檬桉醇成分的精油也是可以有效驅蚊，而尤加利精油就是含有高量的檸檬桉醇，再加上防蚊樹天竺葵讓蚊子討厭的氣味就是最佳天然的防蚊素材。而被蚊蟲咬傷後最需要的就是舒緩，這個任務就交給茶樹精油與薄荷精油，茶樹溫和抗菌消炎、薄荷清涼止癢，可以減緩皮膚被蚊蟲叮咬後的痕癢感受。
調製步驟
1.先調出75%酒精100ml
一般我們購買的優質酒精濃度約為95%，酒精濃度70-75%可以有效的殺菌並可當成油跟水互融介質，我們沒有使用乳化劑來讓油水互融所以使用酒精是最方便的做法。
這裡調製可以75ml酒精加25ml的冷開水或純水即可。
2.加入精油2-3%
蚊子討厭的精油為尤加利與天竺葵，舒緩的部分為茶樹跟薄荷。
尤加利20d(1g)、茶樹14d(0.7g)、天竺葵10d(0.5g)、薄荷6d(0.3g)
3.倒入噴霧瓶就完工了
當然我們也可以購買類似配方的精油防蚊液也能有效的防蚊驅蚊

CDC Adopts New Repellent Guidance for Upcoming Mosquito Season
Americans have more options than ever to use in protecting themselves from mosquito bites. Today, the Centers for Disease Control and Prevention (CDC) released new guidance about effective mosquito repellents available in the United States. The updated guidance includes addition of two active ingredients - picaridin and oil of lemon eucalyptus - which have been shown to offer long-lasting protection against mosquito bites. Repellents containing DEET continue to be a highly effective repellent option and are also included in the CDC guidelines.
Picaridin, also known as KBR 3023, is an ingredient found in many mosquito repellents used in Europe, Australia, Latin America and Asia for some time. Evidence indicates that it works very well, often comparable with DEET products of similar concentration. One product, containing 7 percent picaridin, is being distributed in the United States for the first time this year. The other repellent is oil of lemon eucalyptus (also known as p-menthane 3,8-diol or PMD), a plant-based mosquito repellent that provided protection time similar to low concentration DEET products in two recent studies. It is available in a variety of formulations throughout the United States.
"We're very excited that the number of options people have to protect themselves from mosquitoes and therefore West Nile Virus has increased," said CDC Director Julie L. Gerberding. "Products containing DEET, picaridin and oil of lemon eucalyptus are all excellent choices. The important thing is that they remember to protect themselves from mosquito bites when they're going to be outside. We want people to enjoy their spring and summer free of West Nile Virus."
Mosquito season has already begun in some parts of the country. With mosquitoes comes the risk of West Nile Virus infection and other infections spread by mosquitoes. Just one bite can lead to an infection that could cause serious illness or even death. While people over 50 are more likely to become seriously ill if infected with WNV, people of any age can become mildly to seriously ill. Most people who contract West Nile Virus do not show any symptoms. However, about 20 percent of people experience symptoms such as fever, headache, nausea and vomiting and an estimated 1 in 150 people infected with WNV will develop severe illness. The severe symptoms can include high fever, stupor, disorientation, coma, tremors, convulsions, muscle weakness, vision loss and paralysis.
DEET, picaridin and oil of lemon eucalyptus are all registered with the U.S. Environmental Protection Agency, which regulates these products. Repellents registered with EPA have been evaluated for both safety and efficacy when used according to label instructions.
CDC recommends that people use repellent anytime they go outside, especially during prime mosquito biting hours, between dusk and dawn. People should follow the label instructions, and if they start getting bitten re-apply repellent.
CDC works with state and local health departments, federal and other government agencies, as well as private industry, to prepare for and prevent new cases of West Nile virus infection. CDC coordinates ArboNet, a nation-wide electronic database that gathers information about West Nile virus in humans and animals, in order to guide prevention and response activities.
