Traps, barriers, screens and preventing pest access are examples of what method of pest management?

• A. Biological
• B. Chemical
• C. Cultural
• D. Mechanical

Answer: (D)

Traps, barriers, screens, and preventing pest access are physical actions that block or remove pests without using chemicals or biological agents. This kind of approach is mechanical pest management because it relies on practical, hands-on, physical interventions—catching pests with traps, blocking entry with barriers, and screening to keep pests out. It’s different from chemical methods (which use pesticides), biological methods (which involve living organisms or their products to control pests), and cultural methods (which change the environment or practices to reduce pests). Using mechanical controls often fits well within integrated pest management to lower pest pressure while limiting chemical use.
