Introduction
House flies are not the neatest of insects. They visit such places as dumps, sewers, and garbage heaps. They feed on fecal matter, discharges from wounds and sores, sput and all sorts of moist decaying matter such as spoiled fish, eggs and meat.
Economic importance
House flies are strongly suspected of transmitting at least 65 diseases to humans, including typhoid fever, dysentery, cholera, poliomyelitis, yaws, anthrax, tularemia, leprosy and tuberculosis. Flies regurgitate and excrete wherever they come to rest and thereby mechanically transmit disease organisms.
