What is a characteristic of house flies?

House flies are known for their significance as vectors of disease, primarily because of their feeding habits. They are often found in unsanitary conditions and can feed on decaying organic matter, feces, and other contaminated materials. When they feed, they can pick up bacteria and other pathogens, which can then be transferred to food surfaces or humans as they move about. This ability to spread bacteria makes them a significant concern for public health, emphasizing their role as disease carriers rather than mere pests.

Understanding the behaviors of house flies, including their feeding habits, is crucial for pest management and for addressing the risks they pose in various environments, particularly in agricultural and urban settings.
