Which statement best describes the use of biological pest control measures?

• A. They Are Used Only After Pesticides Fail
• B. They Are Never Used Indoors
• C. They Can Replace More Disruptive Or Hazardous Methods
• D. They Are Effective Against All Pests

Answer: (C)

Biological pest control uses living organisms or their byproducts to suppress pest populations, and its strength lies in reducing reliance on disruptive or hazardous methods. This approach can replace more harmful methods by targeting pests more selectively, lowering environmental impact and minimizing non-target effects. In practice, it’s often used as part of an integrated pest management plan, combining monitoring, preventive tactics, and compatible controls to keep pest levels in check without overusing chemicals. It isn’t limited to situations after pesticides fail, it isn’t confined to indoor use, and it isn’t universally effective against all pests—its success depends on the pest, the available natural enemies, and the environment.
