The common Indian housefly or Musca nebulo is cosmopolitan in distribution and particularly found on organic food and excreta. The body of the adult housefly is divided into a distinct head, thorax and abdomen. The thorax has 3 pairs of legs. The housefly has 1 pair of thin transparent wings.

The housefly undergoes complete metamorphosis. It exhibits all the four stages in its life history-egg, larva, pupa and adult.

It spreads several diseases like dysentery, cholera and typhoid. The housefly picks up germs from filthy places and contaminates the food when it sits on it. The food is also contaminated when it drops excreta while eating on the food or when it regurgitates food, which it has consumed in filthy places.
Flies may be controlled by elimination of breeding places and by spraying of insecticides like DDT. Food should be covered and sleeping infants should be protected by net umbrellas.
