Which method describes non-chemical pest control?

The method of exclusion techniques, such as sealing entry points, is a fundamental component of non-chemical pest control. This approach focuses on preventing pests from entering a space in the first place, thereby reducing reliance on chemical treatments. By identifying and sealing potential entry points in buildings—such as cracks, gaps around windows and doors, and openings in the foundation—property owners can effectively impede pest access and reduce infestations. This method is both preventive and sustainable, promoting a long-term solution to pest management without the use of chemicals.

In contrast, using pesticides in all areas entails a chemical approach, which does not fit the non-chemical definition. Application of organic pesticides, while often seen as a more eco-friendly chemical option, still involves the use of substances that are intended to kill or repel pests, making it part of a chemical control strategy. Similarly, trapping and killing insects involves direct chemical or mechanical intervention to manage pests, which also does not align with the principles of non-chemical pest control.
