This study identified modifiable factors affecting use of nets that were consistent across both surveys. While net replacement remains important, the findings suggest that: more education about use and care of nets; making nets more resistant to damage; and encouraging net mending are likely to maximize the huge investment in scale up of net ownership by ensuring they are used.

Open Access | Claims about the Misuse of Insecticide-Treated Mosquito Nets: Are These Evidence-Based?

Nearly all experts agree that insecticide-treated mosquito nets (ITNs) are a lifesaving intervention, supported by strong evidence from carefully conducted trials that show ITNs to be efficacious at preventing all-cause child mortality and malaria morbidity in children and pregnant women.

Outdoors mosquito sampling methods, namely human landing catch (HLC), ITT (Design B) and resting boxes (RB) were conducted in parallel with indoors sampling using HLC, Centers for Disease Control and Prevention miniature light traps (LT) and RB as well as window exit traps (WET) in urban Dar es Salaam, rotating them thirteen times through a 3 x3 Latin Square experimental design replicated in four blocks of three houses.
