Targeted indoor residual spraying (TIRS) to control Ae. aegypti. In urban environments, houses are primarily built of brick and cement, and Ae. aegypti rests preferentially below 1.5 m of height. Spraying residual insecticides in walls below 1.5 m and in key resting sites such as under furniture (#1 in figure, represented in green) will eventually kill Ae. aegypti that may be emerging from immature larval habitats outdoors (2) and rest indoors on treated surfaces (3). After exposure to the residual insecticide, mortality can occur immediately (4) or after several hours/days (5)
