Oriental Latrine Fly
Chrysomya megacephala
The Oriental Latrine Fly is an introduced species of blowfly that has become a major pest of medical and veterinary importance, particularly in the warmer parts of Australia. As its name suggests, it is strongly attracted to and breeds in decomposing organic matter, especially feces, carrion, and garbage. This behaviour makes it a significant mechanical vector for a wide range of human pathogens, including bacteria that cause dysentery and food poisoning. It is a classic 'filth fly' and its presence is a strong indicator of poor sanitation. In addition to its role as a disease vector, it can also cause myiasis (maggot infestation) in livestock and domestic animals.
For effective control and prevention, professional pest management is recommended.
