What is an effective method to prevent pests in food storage areas during fieldwork?

Using sealed containers is an effective method to prevent pests in food storage areas during fieldwork because it creates a barrier that protects food items from insects and rodents. When food is securely sealed, pests are unable to access it, significantly reducing the risk of contamination and spoilage. This practice helps maintain food safety and hygiene, which is essential in any field operation.

In contrast, leaving food uncovered allows pests direct access to the food, which can lead to infestations and health risks. Storing food in open bags similarly does not provide adequate protection and can attract pests. While using pesticides might seem like an effective approach, it can pose health risks to workers and may not be sustainable as a primary prevention method. Sealing food not only deters pests but also keeps the food fresh and safe for consumption.
