Malaria remains a significant public health concern in Rwanda, particularly in urban areas like Kigali. Effective malaria vector control strategies are essential for reducing mosquito populations and mitigating disease transmission. A randomized controlled trial was conducted, comparing traditional insecticide-treated bed nets (ITNs) with a mobile app-based vector control intervention. Mosquito populations were monitored weekly using electrocuting traps. The mobile health tech model resulted in an average reduction of 25% in mosquito population compared to ITN use alone, with no significant side effects observed. Mobile technology can be a viable and effective tool for malaria vector control, providing substantial benefits over traditional methods. Further research should explore scalability and cost-effectiveness of the mobile tech intervention across different urban settings in Rwanda.
