Why control mosquitoes at all?

Mosquito control emerged at the beginning of this century once it was discovered that they can carry numerous viruses and bacterium, some fatal to man. Yellow Fever and Malaria were once endemic to this region, but are now either extremely rare or have been eliminated. Eastern Encephalitis, and now West Nile Virus, can also occur in Massachusetts, although more sporadically and without widespread human mortality. Mosquitoes have played an important role in the history of mankind — they have stopped wars, spread disease through entire populations, and altered human history in too many ways to count. It is estimated that mosquitoes have killed more human beings than all wars, famines and natural disasters combined — more humans than are alive today. 3-6 million people each year die from malaria alone, and up to 100 million are sickened annually. This is just from 1 disease transmitted by mosquitoes.
