A mosquito net is a protective barrier made from fine mesh fabric designed to prevent mosquitoes and other insects from entering an enclosed area such as a bed, sleeping area, or outdoor space. It is typically suspended above the sleeping area or attached to windows and doors to create a physical barrier that prevents insects from biting and bothering individuals.

Mosquito nets are commonly used in regions where mosquitoes are prevalent, particularly in tropical and subtropical climates where mosquito-borne diseases like malaria, dengue fever, and Zika virus are a concern. They come in various shapes and sizes, including rectangular, circular, and conical, and can be made from materials such as polyester, nylon, or cotton.

The mesh size of a mosquito net is critical as it determines the effectiveness of the barrier. The mesh must be small enough to prevent mosquitoes from passing through while still allowing adequate airflow for comfort. Additionally, mosquito nets may be treated with insecticides to enhance their effectiveness in repelling or killing mosquitoes.

Overall, mosquito nets provide an essential layer of protection against insect bites and the diseases they can transmit, making them a valuable tool for ensuring a good night's sleep and maintaining health in areas where mosquitoes are prevalent.
