Unlike the standard insecticide- treated nets that contain insecticides from the pyrethroid class, these new-generation nets contain additional active ingredients combined with pyrethroids. “This study does not question the value of these nets but it shows that technology alone is not enough. They reduced mosquito biting, killed insecticide-resistant mosquitoes, and lowered malaria transmission better than older, pyrethroid-only nets,” said Moore. The model showed that human behavior—how long people stay in bed, how consistently nets are used, and how quickly nets deteriorate—can be just as important as the insecticides themselves.
