What is the main reason for sealing gaps or holes in structures for pest management?

Sealing gaps or holes in structures is primarily aimed at limiting pest entry and harboring. When pests can find openings in a building, they can easily infiltrate and establish themselves within the space. Many common pests, such as rodents and insects, can fit through surprisingly small openings, making it essential to maintain a sealed environment. By closing off these potential entry points, pest management becomes significantly more effective, reducing the likelihood of infestations.

While preventing water damage, improving building aesthetics, and avoiding energy loss are all valid considerations related to building maintenance, they are secondary benefits in the context of pest management. Sealing is fundamentally about controlling access for pests, which in turn helps to minimize the risks associated with pest-related damage and health concerns within the structure.
