Nothing But Nets
In the poorest parts of the world, where effective window screens are lacking, insecticide-treated bed nets are arguably the most cost-effective way to prevent malaria transmission.
One bed net costs just $10 to buy and deliver to individuals
in need. One bed net can safely last a family for about four years, thanks
to a long-lasting insecticide woven into the net fabric.
Currently, nets are treated with pyrethroid insecticides. These insecticides have very low levels of toxicity to humans, but are highly toxic to insects. By repelling the mosquitoes, a bed net can protect other people in the room outside the net. When enough nets are used in an area, the insecticide used in the net fabric makes entire communities safer even for those individuals who don’t have nets.
