What are "non-chemical" pest control methods?

Non-chemical pest control methods encompass a variety of strategies that aim to manage pest populations without the use of synthetic chemicals. Techniques such as cultural practices and mechanical controls are prime examples of these methods. Cultural practices may include crop rotation, proper sanitation, and selecting pest-resistant plant varieties, all of which help to discourage pest infestations by altering the environment in a way that is less favorable to pests. Mechanical controls involve physical means of pest management, such as traps and barriers, which can be used to directly eliminate pests or prevent them from reaching the plants.

This approach to pest control is often favored because it can reduce reliance on chemical pesticides, contribute to environmental sustainability, and minimize the potential for pesticide resistance. Non-chemical methods can be effective in a range of situations, particularly in integrated pest management (IPM) programs that emphasize a holistic view of pest control that includes various strategies.
