How it works?
While some might think that lemongrass itself repels mosquitoes, actually only the oil obtained from the grass will repel mosquitoes and not the plant itself. So it won’t help to repel mosquitoes when you reside next to the citronella grass.
Citronella oil works by repelling mosquitoes from the skin and do not kill any mosquitoes. It masks scents that mosquitoes are sensing, so when a citronella oil is applied to the skin it blocks scents and they cannot be sensed by mosquitoes. These scents are carbon dioxide and lactic acid. Generally, insects will have much more difficult time locating you, when a citronella oil is applied to the skin. Some resources also suggests that citronella oil repels not only insects but also animals, but this is not scientifically proven.
Citronella oil usually works for about 20 minutes to half an hour and needs to be reapplied after that time has passed. This is significantly lower amount of time compared to DEET and other chemical insect repellents which can work even for couple of hours. As previously mentioned citronella oil is used in different insect repelling products, starting from candles to sprays, lotions and even bracelets that repels mosquitoes. Sprays and lotions are the most successful insect repellents using citronella oil and they usually contain mixture of citronella oils and other substances to increase the work time of the spray. Scanted candles usually proves to be less effective and needs to be used in a close range where people are residing. Many people are making their own insect repellents out of citronella oil in combination with other natural products.
