“Malaria parasites, which kill nearly 600,000 people a year, mostly children, are spread by female mosquitoes when they drink blood.

Current efforts aim to kill mosquitoes with insecticide rather than curing them of malaria.

But a team at Harvard University has found a pair of drugs which can successfully rid the insects of malaria when absorbed through their legs. Coating bed nets in the drug cocktail is the long-term aim…

Nets are both a physical barrier and also contain insecticides which kill mosquitoes that land on them.

But mosquitoes have become resistant to insecticide in many countries so the chemicals no longer kill the insects as effectively as they used to.”
