Sorry, but you are incorrect. Malaria is not an environmental disease. In a nutshell, the plasmodium is carried through the female anopheles mosquito, which transmits the plasmodium to the uninfected person B ONLY after biting infected person A. Mosquitoes are not born with the plasmodium in their bodies but rather get it from human hosts. The mosquito lifespan is only a few weeks. If we eliminate the plasmodium from the human population, then the mosquitoes can no longer carry it.

The US eradicated malaria in the 50s and 60s not by clearing out all the swamps and refuse pits but by putting in public health measures that prevented mosquitoes from biting humans (ie screens on doors and windows became building codes), as well as killing off a lot of mosquitoes with the spread of DDT (which global experts now agree was a bad idea with a good outcome). They also instituted strict quarantine and treatment measures to ensure the malaria infected human would not be able to host the plasmodium and spread it to others if s/he were bitten. Go to the US today - anopheles mosquitoes are still there but the plasmodium was eliminated from our human pool. This is why our Centera for Disease Control are very strict when people travel from malaria endemic areas - there’s still a great risk that malaria can resurface in the population of someone were to carry it over from, Ghana for instance, and then get bitten when in the US.

Of course refuse pits and water logged areas need to be cleaned up but it will do precious little to halt malaria.
