When should non-chemical pest control methods be prioritized?

Non-chemical pest control methods should be prioritized when they are effective and can reduce reliance on chemical pesticides. This approach aligns with integrated pest management (IPM) principles, which advocate for sustainable practices that minimize the use of chemicals. By employing non-chemical methods, such as biological controls, habitat manipulation, and cultural practices, pest populations can be managed in an environmentally friendly manner. This is particularly important for reducing chemical residues in the ecosystem, minimizing harm to non-target organisms, and addressing pest resistance to chemicals. The effectiveness of these methods in combination with chemical controls can lead to more sustainable pest management strategies, making option B the clear choice for prioritization.
