Mosquitoes have been disturbing humans ever since both have co-existed. The earliest records of nets being used to protect people from mosquito bites are from ancient Egypt, but it was not until the early 1980s that the first trials of insecticide impregnated bednets took place. As evidence for the impact of insecticide treated nets (ITNs) on malaria grew, along with the political commitment to win the fight against malaria, technological developments led to a commercial market for long-lasting insecticidal nets (LLINs). Over a billion LLINs have now been distributed in Africa and have been largely credited for reducing malaria cases there by 60%, but the use of one class of insecticide (pyrethroids) in LLINs, has led to growing insecticide resistance in malaria vectors. This, in turn, is threatening the enormous gains that have been made. The arrival of the next generation of LLINs will require not only the technology but also the political will and funding to enable scale-up in the countries that most need it.
