Using barriers to prevent pests from getting into an area is an example of which type of pest management method?

Using barriers to prevent pests from entering an area is classified as mechanical control. This method involves physical means to manage pest populations, such as installing screens, seals, or other physical barriers that restrict access to an environment where pests could cause harm. The intent is to prevent pests from coming into contact with plants, animals, or human structures without using chemical interventions.

Mechanical control methods are highly effective because they can provide immediate and ongoing protection without harming beneficial organisms. In contrast to other pest management strategies, mechanical control focuses on physical alterations to the environment or direct removal of pests rather than employing biological agents, cultural practices, or chemical pesticides. This method can serve as a foundational strategy in an integrated pest management plan, often working in synergy with other control methods for improved pest management outcomes.
