What is a common measure for insect control in food establishments?

Installing screens on doors and windows is a common measure for insect control in food establishments because it acts as a physical barrier that prevents insects from entering the premises while still allowing for ventilation. This method is effective in maintaining air circulation without compromising food safety, as it minimizes the risk of pests contaminating food by entering through open doors or windows.

Using chemical pesticides can be effective, but it often raises concerns regarding chemical residue on food, the health of employees and customers, and potential negative impact on the environment. Likewise, leaving lights on tends to attract insects rather than deter them, and storing food outside is not a viable option for safety and hygiene reasons, as it exposes food to contaminants and increases the risk of spoilage or pest infestation.
