What is the goal of using exclusion in pest management?

The goal of using exclusion in pest management is to prevent pests from entering a structure. This approach focuses on creating physical barriers that eliminate entry points for pests, such as sealing cracks in walls, installing door sweeps, and ensuring windows are properly fitted. By stopping pests from gaining access, it significantly reduces the likelihood of infestations and minimizes the need for chemical treatments. Exclusion is a proactive strategy that forms the foundation of integrated pest management, emphasizing prevention as a critical component for maintaining a pest-free environment.
