Final answer:
The answer is 'None of the above', as successful pest control uses an integrated approach that minimizes environmental harm and relies on natural predators and the prudent use of pesticides.
Step-by-step explanation:
Successful pest control is not based on the ability to eradicate all pests nor is it prudent to use pesticides whenever pests are identified. It also should not aim to contaminate the environment. Integrating various methods, such as chemical, biological, and cultural control, and using them judiciously is known as Integrated Pest Management (IPM). IPM encourages the use of ecologically based control measures and regards pesticides as a last resort to minimize environmental disruption. Biological control, specifically, describes the use of organisms to control pests, and managing landscape complexity can enhance the effectiveness of these natural predators and parasites in controlling pests.
The correct answer to the question is None of the above. Effective pest control should involve an integrated approach that considers environmental impact and sustainability, such as introducing species that prey on pests or reducing the use of synthetic pesticides.
