Which method is considered a non-chemical approach to pest control?

Trapping is recognized as a non-chemical approach to pest control because it relies on physical methods to capture pests rather than employing chemical substances that could potentially affect the environment or non-target organisms. This method can effectively reduce pest populations by physically removing them from an area without introducing chemicals, making it a safer alternative, especially in sensitive environments like homes, schools, or natural areas.

Non-chemical methods like trapping emphasize biological and mechanical means, which can be integrated into an Integrated Pest Management (IPM) approach. By utilizing such strategies, pest control technicians can work towards sustainable pest management practices that minimize ecological disruption and promote the health of surrounding ecosystems.
