Insecticide treated curtains and water jar covers control dengue vector

Window curtains and domestic water container covers treated with insecticide can reduce the population of the mosquito vector for dengue fever and potentially reduce disease transmission. Kroeger and colleagues (p 1247) conducted a cluster randomised controlled trial in 36 urban sectors in Mexico and Venezuela. Sectors were paired according to mosquito infestation, and one sector per pair allocated to intervention. Although reduction in infestation was not significantly bigger in the intervention group after follow-up of 9 or 12 months, the intervention reduced mosquito populations in neighbouring control clusters.
