Are natural products, like essential oil of citronella, as effective as synthetic products?
NO
While essential oils are known for their repellent properties, and while we have used this type of product for many generations, their effectiveness remains limited due to a short duration of action related to the volatility of essential oils. This is why they have steadily been replaced by synthetic products, which are less volatile and have a longer duration of action.
It is therefore strongly recommended not to use these products as mosquito protection in high-risk areas.
