Which method is used for controlling pests through trapping?

The method used for controlling pests through trapping is classified as mechanical control. This approach involves physical means to prevent or reduce pest populations, and trapping is a direct example of this method. Traps can be designed to capture or kill pests, thereby reducing their numbers without the use of chemical pesticides or biological agents.

Mechanical control is often favored for its straightforwardness and can be effective in managing specific pest issues while minimizing environmental impact. It also has the benefit of being safe for humans and non-target species when utilized correctly.

The other options pertain to different strategies; chemical control focuses on the use of pesticides, biological control involves using natural predators or pathogens to manage pests, and integrated pest management combines various techniques, including trapping, but is more holistic and complex in its approach.
