A mosquito net is a protective barrier made from finely woven mesh material designed to keep mosquitoes and other insects away from individuals. It is typically used in areas where mosquito-borne diseases, such as malaria and dengue, are common. Mosquito nets can be suspended over beds, used in tents, or installed around windows and doors. They are usually lightweight, breathable, and come in various sizes to fit different needs, from single bed nets to larger ones for multiple people. Some mosquito nets are treated with insect-repellent chemicals for added effectiveness.
