What is an example of a non-chemical pest control method?

• A. Using chemical repellents
• B. Biological control, such as using natural predators to manage pest populations
• C. Chemical spraying as a preventive measure
• D. Using traps with pesticides

Answer: (B)

Biological control, which includes the use of natural predators to manage pest populations, is an excellent example of a non-chemical pest control method. This approach relies on the natural balance within ecosystems, where certain organisms, such as beneficial insects, birds, or even plants, can effectively reduce pest numbers without the need for synthetic chemicals. By introducing or encouraging these natural predators, farmers and pest controllers can manage pest outbreaks in an environmentally friendly manner. In contrast, using chemical repellents, chemical spraying, and traps with pesticides all involve the application of chemical substances to deal with pest issues. These methods can be effective but often carry risks such as environmental contamination, harm to non-target species, and the development of pest resistance. Emphasizing non-chemical methods like biological control supports sustainable agricultural practices and minimizes reliance on chemicals, making it a preferred option for many pest management strategies.
