Which pest management principle focuses on the physical aspect of pest removal?

The correct answer is focused on the principle of mechanical control, which emphasizes the physical means of pest removal rather than relying on biological, cultural, or chemical interventions. Mechanical control methods include techniques such as trapping, hand-picking pests, vacuuming, and using barriers or screens to exclude pests from areas where they are not wanted.

This approach is considered effective for managing pest populations because it directly eliminates pests from the environment without the need for chemicals or biological agents. Implementing mechanical control can help reduce pest numbers while minimizing impacts on non-target organisms and the surrounding ecosystem.

Understanding mechanical control is crucial in integrated pest management (IPM) strategies, as it promotes a tangible and often immediate response to pest issues by utilizing tools and devices that physically disrupt pest activities or remove them from situations where they pose problems.
