Can Pomelo be a mosquito repellant?

Yes. My mother has been practicing this for many, many years now. Indigenous knowledge? Probably. According to her, this practice is common in their barangay since she was young. She is now 67 years old and she came from a rice farming community in Cagayan Valley. She puts few fresh leaves of pomelo depending on the amount of rice to be poured in our rice dispenser and it works! No bugs in our rice. You just have to change the pomelo leaves every time you put another sack of rice in your dispenser.
