Which pest management practice involves the use of non-chemical means?

The practice of pest management that involves the use of non-chemical means encompasses various strategies, including biological control, mechanical traps, and sanitation measures.

Biological control relies on natural predators or parasites to manage pest populations, effectively utilizing the ecological balance in an environment without introducing synthetic chemicals. This can include introducing beneficial insects that prey on harmful pests.

Mechanical traps are physical devices designed to capture or kill pests without the use of chemical pesticides. These traps can include sticky boards, snap traps, or various types of barriers that prevent pest movement.

Sanitation measures involve the maintenance of a clean environment to eliminate potential pest habitats and food sources. This can include regular cleaning of living spaces, proper waste disposal, and eliminating standing water, all aimed at making the environment less conducive for pests to thrive.

Given that all these practices are viable non-chemical methods for pest management, the correct answer indicates that a comprehensive approach utilizes multiple strategies simultaneously to effectively manage pest issues.
