Mosquito net

A mesh barrier that keeps mosquitoes and other insects away from people, commonly suspended over beds or enclosing outdoor spaces.

Insecticide-treated net: A mosquito net treated with insecticide to repel or kill mosquitoes that contact it. It adds chemical protection to the physical barrier, reducing malaria transmission during sleep.
Insect screen: A porous mesh barrier that permits airflow while blocking insects from passing through. A mosquito net is a wearable or suspended form of insect screen.
Mosquito control: Methods used to reduce mosquito populations or limit their contact with people. Mosquito nets are one personal barrier within broader control efforts.
Malaria: A potentially severe disease caused by Plasmodium parasites and transmitted to people by infected female Anopheles mosquitoes. Nets reduce nighttime exposure to the mosquitoes that spread malaria.
Mosquito repellent: A substance applied to skin or clothing to discourage mosquitoes from landing or biting. Repellent moves with a person, while a net protects only within its enclosed space.
Long-lasting insecticidal net: A factory-treated mosquito net designed to retain insecticidal activity through repeated washing and years of use. It is the standard form distributed in many malaria-control programs.
Mesh: A material made by interlacing or joining strands to create a regular pattern of openings. Its openings must block mosquitoes while preserving ventilation.
Ronald Ross: A British physician who demonstrated in 1897 that mosquitoes transmit malaria parasites between birds. His discovery helped establish mosquitoes as targets for malaria prevention.
Anopheles: A genus of mosquitoes that includes species capable of transmitting malaria parasites to humans. Many malaria vectors bite at night, when people are protected by bed nets.
Indoor residual spraying: The application of long-lasting insecticide to interior walls where mosquitoes rest. It treats mosquito resting surfaces rather than placing a mesh barrier around people.
