Everyone is familiar with house flies. Common household pests, they visit dumps, sewers and garbage heaps, feeding on fecal matter, discharges from wounds and sores, sputum, and all sorts of moist, decaying matter such as spoiled fish, eggs and meat. Flies regurgitate and excrete wherever they come to rest and thereby are ideally suited to mechanically transmit disease organisms. House flies are suspected of transmitting at least 65 diseases to humans.
