Interceptor G2 Dual-Insecticide Bed Net Initiative

Tanzania, Benin, Sub-Saharan Africa, Sub-Saharan Africa

The Gates Foundation supported development and scale-up of next-generation insecticide-treated bed nets to combat growing pyrethroid resistance in malaria-endemic regions. The Interceptor G2 net uses dual insecticides (pyrethroid + chlorfenapyr), reducing malaria infection among children by nearly half in trials in Tanzania and Benin. The initiative combines technology innovation with behavior change campaigns to ensure proper and consistent bed net use, partnering with countries for digitized distribution systems.

Behavior Goal

Increase consistent bed net use and acceptance of next-generation nets to reduce malaria transmission despite insecticide resistance

Implementers & Partners

  • Gates Foundation
  • Catholic Relief Services
  • WHO
  • Researchers at LSHTM

Key Takeaways

  • 1Dual-insecticide nets overcome pyrethroid resistance in mosquitoes
  • 2Nearly 50% reduction in childhood malaria infections in trials
  • 3Estimated 13 million cases prevented and 25,000 lives saved (2019-2022)
  • 4Digitized distribution systems improve efficiency and household coverage
  • 5Behavior change essential - compliance declines without community engagement
