Sealing cracks and crevices and small openings in buildings is an example of which type of pest management method?

Sealing cracks and crevices and small openings in buildings is categorized as a physical pest management method. Physical control methods involve non-chemical strategies to prevent or eliminate pests. By sealing these entry points, you are physically obstructing pests from accessing the interior of a structure, thus reducing the likelihood of infestations.

This method is effective because many pests, such as rodents and insects, require specific entry points to gain access to food and shelter. By implementing physical barriers, pest invasions can be significantly curtailed, showcasing the importance of preventive measures in a comprehensive pest management strategy.

Other methods, such as biological (involving natural predators or parasites), cultural (changes in practices to make the environment less conducive to pests), and mechanical (using devices or tools to remove pests), do not involve creating physical barriers to stop pests at the entry points. Thus, the focus of sealing openings directly aligns with the principles of physical pest management.
