Which of the following methods is NOT considered a part of mechanical pest control?

Mechanical pest control focuses on physical methods to manage pest populations without the use of chemicals. This includes practices such as trapping, sealing entry points, and creating physical barriers, which all fall under this category as they involve direct physical actions to prevent or eliminate pests.

The use of biological pesticides, however, involves organisms or substances derived from living organisms to control pests. This method relies on biological processes rather than physical manipulation, which sets it apart from mechanical control methods. Consequently, it does not belong to the mechanical pest control category. Understanding the distinction between mechanical and biological pest control is essential for effective pest management strategies.
