The problem

Spraying the walls and eaves of houses with insecticide is a long-used strategy for killing malaria-carrying mosquitoes. But with extended exposure, mosquito populations become resistant to the sprays they most frequently encounter. When the sprays weaken against the mosquitoes, spraying drops off in communities, giving malaria the chance to surge. At this project’s inception, indoor residual spraying had decreased about 40 percent over the previous few years because the older products were becoming ineffective, and the newer ones were too expensive.

Our response

The NgenIRS project aimed to usher in new indoor sprays for homes across 16 African countries, lower the price of the only next-generation insecticide available at the time, and bring more of these sprays to the market.

The project created a competitive and growing market for third-generation indoor residual spraying (3GIRS) products. By working with several manufacturers, fueling demand and underwriting a fixed quantity purchase, the project managed to achieve a median price reduction of 35% and support quality approval of three 3GIRS products.
