What type of pest management method do barriers that prevent pests from entering represent?

Barriers that prevent pests from entering a specific area exemplify mechanical control methods in pest management. This strategy involves physical barriers or devices designed to obstruct pests from accessing plants or turf. Examples of such barriers include screens, nets, and fences that are strategically placed to shield vulnerable plants from potential pest invasions.

Mechanical control is a proactive approach, focusing on preventing pests from causing harm rather than reacting to their presence. This method is often environmentally friendly since it does not rely on chemicals or biological agents, making it suitable for use in various settings, including residential lawns and ornamental gardens. Understanding the benefits of mechanical control can help in developing a comprehensive integrated pest management plan that minimizes reliance on other methods, such as chemical control or biological agents.
