What does the term 'non-chemical pest control methods' refer to?

The term 'non-chemical pest control methods' refers to approaches that utilize physical and cultural practices for managing pests without relying on chemical solutions. This encompasses a variety of techniques, including physical barriers (like nets), manual removal of pests, and cultural practices that create an environment less conducive to pest infestations, such as crop rotation and proper sanitation.

In contrast, methods that rely solely on chemical solutions to eliminate pests are categorized as chemical pest control methods, which is not what is being asked about. The mention of biological controls, such as utilizing natural predators, does constitute a non-chemical approach, but focusing exclusively on this narrow aspect does not encompass the full definition of non-chemical methods. Similarly, standard pesticides with lower toxicity still fall under the category of chemical methods, so they do not fit the definition of non-chemical pest control practices.
