Musca domestica

House fly


Houseflies are a well-known pest of farm and home. Believed to have originated in central Asia, the insect expanded its range worldwide long ago as a commensal organism to human populations; the housefly is always found in association with human activity. As the most common species of fly found on livestock farms, they represent both a nuisance and a risk for disease transmission. High-density housing systems and abundant manure production create the ideal conditions for maggot development. In extreme cases, large fly populations can even create public health issues for the communities surrounding a farm.
