So, health authorities have been working on the twin challenges of eradicating mosquitoes and educating people.

Many insects, like the viruses that attack the human body, reproduce quickly and can develop resistance to whatever we throw against them. As doctors turn from one antibiotic to another to find one that still kills a given virus, so health officials experiment to see what still kills different mosquito species.
