In an attempt to find safe and ecofriendly plant-based insect repellents, researchers tested 23 essential oils for their mosquito-repelling properties, specifically against Aedes Aegypti. Three essential oils outperformed the rest: litsea, geranium and rosewood oils.
In this particular study, the top 10 mosquito-repelling essential oils were identified as the following, listed in order of highest effectiveness:
Litsea
Rosewood
Geranium
Lemongrass
Lemon scented Camphor
Citronella
