Indoor Residual Spraying (IRS)

Indoor Residual Spraying (IRS) is a method used to control mosquito populations and prevent malaria transmission. It involves applying insecticide to the interior walls and ceilings of homes, where mosquitoes often rest after feeding. The insecticide remains effective for several months, killing mosquitoes that land on treated surfaces. This targeted approach reduces the number of mosquitoes in the area, thereby decreasing the risk of malaria infection among residents. IRS is a key public health tool, particularly in areas where malaria is common, and is typically carried out by trained health workers using specialized equipment.
