Name a method of controlling flies in food establishments.

Installing air curtains or screens on doors is an effective method of controlling flies in food establishments. Air curtains create a barrier of air that can deter flying insects from entering the premises while still allowing for easy access for customers and staff. This method is particularly beneficial as it does not obstruct the entry and exit points, unlike physical screens that may hamper movement. Additionally, air curtains can be activated only when doors are open, further enhancing their effectiveness in preventing flies from entering.

Effective pest control in food establishments is critical for maintaining hygiene and preventing contamination. Physical barriers like screens, combined with air curtains, serve to minimize the presence of pests without relying heavily on chemical solutions, which can pose health risks or cause allergies to both staff and customers. This approach aligns with integrated pest management practices, focusing on prevention and reducing reliance on pesticides.
