How and why do mosquito nets work?
The female Anopheles mosquito, which spreads malaria by transmitting the Plasmodium parasite to humans, is nocturnal. She only bites at night. Therefore, an insecticide-treated bed net can be an extremely effective tool in the prevention of malaria. A mosquito net is hung up over the middle of a bed so that it completely covers one or more sleeping persons. Mosquito nets not only create a barrier to mosquitoes, but the insecticide kills mosquitoes on contact as well, creating limited protection even for family members sleeping outside the net.
