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

Sealing cracks and crevices in buildings falls under the physical pest management method. This approach involves employing physical barriers, which can effectively prevent pests from entering or moving within a structure. By sealing openings, you reduce access points for insects, rodents, and other pests, thereby minimizing potential infestations.

This method is proactive and focuses on modifying the environment to make it less conducive to pest presence, which is a key aspect of integrated pest management practices. In this case, the sealing acts as a physical barrier, showing the importance of altering the physical landscape of buildings to prevent pest intrusion.

Other methods mentioned in the options, such as mechanical, biological, and cultural methods, serve different purposes and involve different techniques that do not directly relate to the concept of sealing as a means to manage pest entry.
