Final answer:
One basic rule to keep operations pest-free is to seal cracks and holes in the building's structure. This physical control method is part of a preventative strategy that reduces the need for chemical pesticides and minimizes waste and environmental impact. The correct option is (C).
Explanation:
One of the three basic rules to keeping operations pest-free is C) Seal cracks and holes in the building's structure to prevent pest entry. Ensuring the integrity of the physical structure is a vital part of a pest management plan. This involves mechanical/physical control methods, which may include using screens on windows and doors, applying weather stripping, or sealing other points of entry that pests could use to gain access to the facility.
Preventive strategies should be the first line of defense in pest management. By creating an environment that limits the introduction and spread of pests, operations can reduce reliance on chemical pesticides, which should be used safely and as a last resort. It's essential to minimize waste by purchasing only the necessary amount of pesticides, following label instructions for storage, and securely containing any spills or leaks to prevent environmental contamination.
In summary, maintaining a strong physical barrier to deter pests from entering, engaging in consistent cleanup and monitoring procedures, and using chemical controls judiciously combined with appropriate safety measures can lead to effective pest management while also safeguarding human health and the environment.
