How does Neem oil repel mosquitoes?
Neem oil has a very strong bitter smell which is intolerable for mosquitoes. Neem oil contains many phytochemicals, including toxins for insect protection. The primary active compound present in neem oil – “azadirachtin”, interferes with the hormone systems inside the mosquitoes and disrupts their biological growth (molting) process, thus preventing them from growing and laying eggs.
The other active compounds that are present in neem oil – nimbin and salannin, are responsible for its anti-bacterial, anti-fungal and anti-inflammatory properties.
When applied on skin, the bitter odor that releases from neem oil forms a barrier on skin that prevents mosquitoes from finding and locating humans, as it masks the carbon dioxide and lactic acid emitted from humans. When applied through sprays, the neem oil interferes with their olfactory senses with its strong bitter odor which is highly unpleasant and intolerable for mosquitoes.
