Insecticide-treated bed nets are special nets designed to protect people from insect bites, especially from mosquitoes that can spread diseases like malaria. These nets are coated with a safe insecticide that kills or repels insects, making them an effective barrier while people sleep. They are usually hung over beds or sleeping areas to create a protective shield. Using these bed nets is a simple yet powerful way to reduce the risk of insect-borne illnesses. Many health organizations promote their use in areas where diseases like malaria are common, helping to save lives and improve overall health in affected communities.
