How do mosquito repellent essential oils work

Each essential oil is made up of different complex chemicals. The particular chemicals and molecules that these essential oils contain, simply mask the smells that the mosquitos are attracted to.   To repel mosquitos and other bugs it is the essential oil that is needed rather then just the plant.  Using the lemongrass essential oil, will be far more effective than simply using the lemongrass stalks.

It is also worth noting that while warming the oils, either by way of a burner or candle, or applying to our skin, which in itself will warm the oils, will release the fragrances of the essential oils, thus bringing them into the air to repel the mosquito, as the aromas evaporate, which they will do after about 2 hours, the effects wear off.  It is important to replenish whatever method you are using after this time, to ensure continued protection.

Precautions of essential oils to repel mosquitos

Most essential oils are safe to use on the skin in small amounts as long as they are blended with a carrier substance.

Do not use essential oils neat on the skin – apart from a dab of tea tree, that can be applied directly to a mosquito bite.  

Some essential oils cannot be used topically during pregnancy; Citronella, Cedarwood, Thyme, Melissa, White Camphor.
