Humans bear a large part of the responsibility. The study showed that the change in the natural environment resulting from various human activities was the main reason for the spread of house flies. The latter has negative consequences for human and animal health and the economic sector. The control is based on chemical and, to a lesser extent, mechanical methods. At the same time, biological methods are completely absent. Changing human behaviours can play an important role in combating this phenomenon.Arhouse flies, Spread, Environmental conditions, wadi Souf.الذباب المنزليMaster
