原文：Update 11/10/2014:Executive summary or tl;dr: When applied correctly, this works as well as DEET on mosquitoes. Approved by governmental agencies for use in malaria-prone areas. EXTREMELY SMELLY. Buy and use it with confidence.I have been using this product to repel mosquitoes exclusively for seven
years. I became so confident in it that I volunteered to survey wildlife in New England bogs and swamps for six years running. I can't think of a better test than standing around in prime mosquito territory for four hours at a time just daring them to bite. It works every time and they don't get their free lunch. I also used it in Alaska, Kenya, and India and was NEVER BITTEN.This is the only non-DEET product that the International Travel Clinic at Dartmouth-Hitchcock recommends to those with destinations in malaria-prone countries, and oil of lemon eucalyptus is one of only two non-DEET chemicals approved by the CDC.There are many reviews here that say this product didn't work well for them. I wonder if it may be that some people are not applying it correctly. This is an oil, not an aerosol, and it must be applied like sunscreen. The pump is merely for convenience. You spray some on, and then rub it over the entire area to be protected. If you fail to cover everything, the mosquitoes will home in on the uncovered area and bite there instead. You must apply this to your skin UNDER your clothes! Mosquitoes can bite through jeans, so thin summer shirts and shorts are no barrier to them.You must also apply enough of the oil. If you stretch it too thin, it will not protect you. I cannot overstate how PUNGENT this stuff is; I wonder if some people don't apply enough because of the strong smell. You may have to try different amounts a few times until you find the amount that works right for you. Still, you don't have to slather on half a bottle or anything. The quickest I've ever gone through a supply was the one summer where I spent four days a week of swamp slogging with eight hours logged each day, and that only used one bottle. I'm pretty sure most people won't need nearly as much.You must re-apply the oil at regular intervals. The effectiveness will wear off long BEFORE the smell does, so many people may think they are still protected when they are not. Re-apply every four to six hours. As an oil, this stuff is somewhat water resistant, but you will have to reapply sooner if you are swimming.Another reason why people may think this isn't working is because it only keeps the mosquitoes from biting. It won't keep them from seeking you out. This is because it does not jam their long range radar, only the short range. A mosquito tracks potential prey using different senses when hunting for a potential lunch, than when it is looking for the safest place to bite an already discovered one. What happens with this stuff is they get close, and then get really confused. It's like they can see you until they get within a foot, and then you disappear. You can have several mosquitoes hovering around you, but none of them can find a good place to bite. They eventually give up and look for a less confusing blood source.Lemon Eucalyptus will NOT work for you if you primarily want to repel black flies, ticks, or chiggers. In my experience, it is only so-so in repelling deer flies.Finally, this stuff is AMAZINGLY SMELLY. In outdoor environments, this usually isn't a problem. But you really, really, really don't want to apply it before getting in a small enclosed space like an elevator or a car. Even outside, some people will hate the smell, others like it better than the DEET spray alternatives. It kinda smells like cough drops mixed with citronella. Unlike most repellents, the smell does not fade much with time. You are going to smell like this until you shower. If you wore clothes over it, they will smell of it until they are washed. But I think the smell is a small price to pay to stay bite-free.Original review from 2007:I am allergic to Deet. I've been the one at the back of the camping/hiking/fishing trips silently feeding millions of mosquitoes and other biting insects in misery for years- until now. I've tried everything on the market and was always disappointed, since all the deet free products I tried either triggered my allergies or just plain didn't work. This year, my doctor recommended I try the deet-free Repel, and I am sold. The difference is like night and day. We took it on a trip photographing butterflies and dragonflies in swamps in the Rio Grande Valley, TX, and came away bite free. Didn't work on chiggers, but I don't think it's supposed to. I'm not sure it lasts as long as the deet-containing products- my husband started using it exclusively as well, and he has to apply it more often than the Off or Cutter products he used to use. But I'm talking a drop from six hours of effectiveness to four, hardly a problem if you have room in your pack to carry the stuff. Also, it smells like Eucalyptus, which some people don't like, and you will smell of it for HOURS, even after it has lost it's effectiveness or until you take a shower.

执行摘要或tl; dr：
使用正确的方法时就会起到立竿见影的效果。经政府机构批准用于疟疾多发地区，因此非常自信地买下了。
这七年来，我一直在使用这款产品驱蚊，因此在新英格兰沼泽地调查了六年的时间里，我一直很自信。我想没有什么比一个站在蚊子区天天忍受蚊虫叮咬的人说的话更有说服力了，每一次都非常有用。我也在阿拉斯加、肯尼亚以及印度使用过，从来没被咬过。
这是达特茅斯 - 希区柯克国际旅行社推荐给疟疾易发国家目的地的无驱蚊胺产品，而且柠檬桉树油是CDC批准的两种不含驱蚊胺的化学产品之一。
有很多买家说，产品效果不好，我想是不是因为他们的使用方法不恰当。这是含油的驱蚊水，而不是气溶胶，要用防晒霜的手法使用它。按压泵很方便，你只要喷出一点，擦在要防护的地方，如果你不擦遍全身，就会给蚊子留下可乘之机。切记，不要以为穿了衣服就可以不用擦了！就算是有衣服挡着也要擦！蚊子能够透过牛仔裤咬到你，所以你穿薄薄的夏季衬衫和短裤是没有用的！
用量要多！涂薄薄的一层根本没什么用，我没有过度地褒奖这款产品，但是我想一定是有人嫌味道重就擦得很少才没有效果！你可以试一下擦多少量才对你真正起作用，同样，你不必用掉大半瓶涂得超级厚的。讲讲我的情况吧，我用的最快的一次是在一个夏天，我每周要花四天在沼泽地里调研，每天花八小时，所以每次都被飞来飞去的蚊子盯上，但是我也只是用了一瓶，所以正常情况的话，也没必要用这么多。
你还要定时地重新涂上，因为效果会慢慢消失，但是人们还以为一直受保护。所以我建议大家每过四到六小时就涂一次，还有，如果你要游泳的话，也还是早早涂上，因为虽然它防水，但是以防万一嘛。
还有人觉得这款驱蚊水只能防止蚊虫叮咬，却不能真正意义上让蚊子不要出现，这是因为驱蚊水的作用范围较短，不能大面积地进行抵抗。蚊子在寻找猎物时，会利用不同的感官追踪潜在的猎物，而不是寻找最安全的地方咬住一个已发现的猎物。而这款驱蚊水的作用就是在它们靠近你的时候给它们制造出假象，也就是说，蚊子在一步之遥的地方发现了你，但是却因为被气味迷惑而以为你不见了。也许仍然有几只蚊子在你身边徘徊，但是它们根本无法咬你，所以到最后还是会放弃，然后去寻找下一个猎物。
如果你想防止黑色苍蝇、蜱虫或恙螨，那这款驱蚊水可能不大适合你。在我的印象中，这种效果是微乎其微的。
最后想说，这款驱蚊水的味道很大，在室外可能不成问题，但是一进入
电梯或汽车等小型封闭空间味道就会很明显，所以建议在进入小空间以前不要使用。在室外的时候，有一些人会讨厌这种气味，但也有人会选择选择这种驱蚊水作为含驱蚊胺喷雾的替代品。它的味道有点像止咳药片和香茅的混合，与大多数驱虫剂不同，这款驱蚊水的气味不会随着时间而变淡，只有洗澡以后味道才会消失，而且衣服也要等到洗了之后，残留的味道才会消失。不过我觉得为了能起到效果，味道大一点也没什么。
2007年的原始评论：
我对驱蚊胺过敏，所以在野营、远足亦或是钓鱼这些活动中都要饱受蚊子之苦，直到现在，终于解脱了！我几乎试遍了市面上的所有产品，结果大失所望，那些不含驱蚊胺的驱蚊产品要么会让我过敏要么就是味道很淡不起作用。今年，我的医生给我推荐了这款产品，所以我就买来试试，结果效果是天差地别。我参加了在德克萨斯州里约热内卢格兰德谷的沼泽地拍摄蝴蝶和蜻蜓的旅行，而且意外地没有被咬，只是它对恙螨不起作用。我不知道它的效果会不会像含驱蚊胺的产品一样持久，但是我的丈夫也开始使用了，他以前是经常使用Off 或者Cutter产品的。我们把使用频率从六小时降到四小时，只要有足够空间携带不成问题。对了，它闻起来的味道有点像桉树。
