Effective bednets have a relatively short shelf life due to both loss of insecticide and physical damage.
People in target regions can and do buy bednets, though for much of the target market the cost might still represent a day’s income so they won’t necessarily be inclined to replace them at optimal intervals. (On the other hand, it’s a tiny fraction of a typical GiveDirectly handout, which is probably why “people buy bednets with it” isn’t a major feature of their research even in regions with significant malaria). Consumers see [not necessarily as effective] alternative products purporting to achieve mosquito control in the same shops , and won’t necessarily prioritise purchasing replacement nets when it represents a large spend for them, their reason for doing so is the existing bednet doesn’t seem to be working, and people who are relatively informed about malaria prevention are also informed that governments and NGOs tend to dispense bednets for free… Programmes dispensing free nets tend to provide advice on using them properly too.
Bednets on sale in some local markets are often untreated, so buying replacements locally isn’t necessarily even a good decision.
