In pest management, what does 'Exclusion' involve?

Exclusion involves implementing physical or chemical barriers that prevent pests from gaining access to certain areas. This practice is a fundamental part of integrated pest management (IPM) strategies as it aims to stop pests from entering or infesting spaces, thereby minimizing the need for chemical interventions and promoting a healthier environment. By effectively blocking entry points, such as cracks, openings, or using screens, exclusion not only helps in managing existing pests but also plays a crucial role in preventing future infestations. This proactive approach is especially valuable in maintaining the integrity of aquatic environments, where invasive pest species can significantly disrupt ecosystems.
