Your mother sprays kerosene oil on stagnant water to prevent mosquito breeding. Kerosene creates a thin film on the water surface, which interferes with mosquito larvae breathing, thereby reducing their chances of growing into adult mosquitoes and spreading diseases.
I have seen my mother spraying kerosene oil on stagnant water. Why does she do so?

Your mother sprays kerosene oil on stagnant water to combat mosquito breeding. Stagnant water serves as a breeding ground for mosquitoes, where larvae develop. Kerosene oil forms a thin layer on the water surface, which disrupts the larvae’s ability to breathe. This prevents their development into adult mosquitoes, effectively reducing their population. By controlling mosquito breeding sites, she helps prevent the spread of mosquito-borne diseases like malaria and dengue fever. This method is a common and effective way to manage mosquito populations.
