Does natron (or similar compounds) work against malaria mosquitoes?

– a proposal for health and economic growth.

I read at Wikipedia that natron (Na2CO3) was an ancient household insecticide. I don`t know how it works, but it can possibly somehow act on the carbonic anhydrase (CA) enzymes in red blood cells (and from plant feed), and thus interfere in the CO2 / CO3–/ H+ / O2 cycle. It has a wide geological occurrence, is cheap, environmentally friendly and worth a try! Mosquitoes live on blood and nectar, and natron can maybe impede their digestion. Maybe the gut bursts as CA transforms HCO3- and H+ to CO2 and H2O, before the digestive enzymes break CA down!
And since the mosquitoes lay their eggs in lakes, and natron exists in arid water beds, it should be natural to spread it on water surfaces. Female mosquitoes hunt their blood host by detecting carbon dioxide, and an increase in this stuff should lure them.

After further reading, I found that mosquitoes and their larvae produce their own carbonic anhydrase enzymes in the gut. Their anterior gut has a high pH, and the enzymes` main function is to convert CO2 to H2CO3. By adding Na2CO3, the enzymes will work in reverse, producing much CO2 which hopefully could destroy the mosquitoes.
