What is the most important fly control measure that can be applied in most cases?

Basic sanitation is the most important fly control measure because it addresses the root causes that attract and sustain fly populations. Flies are often drawn to areas with food, waste, and other organic materials that provide breeding sites and food. By implementing rigorous sanitation practices, such as proper disposal of garbage, cleaning food preparation areas, and managing composting processes, the environment becomes less hospitable for flies to breed and thrive.

While chemical treatments can eliminate existing fly populations, they do not prevent new flies from entering or breeding in the environment. Screening windows and exclusion methods can help reduce fly access, but they are most effective when combined with sanitation practices. Ultimately, maintaining a clean environment is key to long-term fly control and prevention, ensuring that potential breeding grounds are minimized and reducing the likelihood of infestations.
