What is the primary objective of exclusion in pest management?

The primary objective of exclusion in pest management is to avoid the introduction of pests. This strategy focuses on preventing pests from entering an area where they could cause harm, whether it be to crops, structures, or ecosystems. By using physical barriers, such as screens and sealed entry points, along with cultural practices that reduce the likelihood of pest establishment, exclusion aims to safeguard resources from pest damage right from the outset.

This proactive approach is essential in integrated pest management (IPM) as it minimizes the need for chemical interventions, leading to better environmental stewardship and reduced pest populations over time. Keeping pests out not only protects existing crops or ecosystems but also plays a critical role in maintaining overall agricultural health and sustainability.
