Common House Fly

House flies are ubiquitous and found globally, especially in close association with humans and domestic animals. They thrive in environments with decaying organic matter, such as garbage, compost piles, animal waste, and food waste. They are common in homes, farms, restaurants, and urban areas.

House flies are generalist feeders and consume a wide range of liquefied substances, including decaying organic matter, feces, spilled food, and sugary liquids. They regurgitate digestive juices onto solid food to liquefy it before ingesting.

Flies are highly mobile and are strong fliers. Many species are attracted to light. They undergo complete metamorphosis with egg, larval (maggot), pupal, and adult stages. Larvae often thrive in decaying organic matter or moist environments.

Potential risks include serving as mechanical vectors for numerous pathogens (bacteria, viruses, parasites) causing diseases like typhoid fever, cholera, dysentery, and food poisoning, by transferring them from contaminated surfaces to food. They can also cause annoyance and irritation due to their presence. Benefits are limited but they can play a minor role in decomposition of organic matter.
