A mosquito net (also called supaneti in some areas) is a protective mesh fabric that helps prevent mosquito bites, particularly while you're sleeping. It's usually hung over a bed or sleeping area, creating a barrier between you and any mosquitoes or other insects. The mesh allows air to flow through, so it doesn’t trap heat, but it keeps mosquitoes out. Some nets are treated with insecticides like permethrin, which kills mosquitoes on contact, offering extra protection. Mosquito nets are especially useful in regions where mosquito-borne diseases like malaria or dengue fever are common.
