Ceylon cinnamon oil comes top in new research into natural mosquito repellents

Certain essential oils are exempted from pesticide registration by the U. S. Environmental Protection Agency because they pose a minimum risk to human health.  Consumers are increasingly interested in these natural alternatives to toxic chemical products.   A team at New Mexico State University has been lab testing the mosquito repellent effect of these natural oils.   This is the first time such research has been conducted and the results came as a surprise.

The surprise winners

The research, published in November 2019 in the Journal of Medical Entomology, measured the mosquito repellent effect of 21 essential oils.   The team found that only three of the oils – garlic, spearmint and Ceylon cinnamon – “are truly repellents that cause mosquitos to fly away from the odor source”.  Further, cinnamon oil is “the most persistent, effective mosquito repellent according to our test results”, repelling mosquitos for 90 minutes after application. 

This confirms the findings of the London School of Hygiene and Tropical Medicine, which concluded after lab testing in June 2019 that our cinnamon oil-based Canelle Spray is 97% effective as a mosquito repellent for at least 90 minutes.

Old favourites proved ineffective

The research team found that, of the two oils most commonly marketed as mosquito repellents, citronella oil “is not an effective repellent” and that lemongrass oil “resulted in only a small reduction in attraction”.

The research team also looked at commercially available sprays that contained various combinations of essential oils but found that the products produced only “weak, short-lived repellency effects”.  None of these combination products contained any cinnamon oil.

Ceylon cinnamon oil is the way forward

This news is a real breakthrough for us as producers of Canelle Spray and for all Ceylon cinnamon farmers and oil producers in Sri Lanka.  Now you know that you don’t have to use DEET-based or other toxic chemical products and you needn’t waste your money on ineffective natural repellents such as citronella.  Ceylon cinnamon oil, farmed sustainably in Sri Lanka, is the way forward.
