The study showed that community-scale distribution of free topical mosquito repellents in Cambodia did not reduce malaria transmission because of human behaviour. In the study area, a high proportion of malaria vectors bite outdoors in the evenings when people are active; therefore, theoretically a mosquito repellent could prevent malaria in this setting. However, even though the repellent was freely available and highly effective, the authors also did a mixed-methods study and discovered that only 8% of participants regularly used it, despite 70% reporting daily use.
