In Kazakhstan we're using nets because of mosquitos. Flies are not a real issue, they're a nuisance, but not a big deal. Mosquitos on the other hand are real night-killers. Few of them might keep me awake until sunset with their buzzing. Of course preventing flies is a good side effect.

In South Asia, I could imagine that mosquitos are more dangerous because of diseases they transmit.
