What is an example of mechanical control?

• A. Sanitation
• B. Quarantine
• C. Release of predators
• D. Traps

Answer: (D)

Mechanical control uses physical means to reduce pests by directly removing, trapping, or blocking them. Traps are a classic example because they rely on capturing or killing pests through a physical device rather than chemicals or living organisms. Whether a snap trap, sticky trap, or pheromone trap, the pest is dealt with by a tangible mechanism that interrupts its presence in the area. The other approaches operate through different principles. Sanitation focuses on removing food, water, and harborage to deter pests—it's about habitat management rather than a physical tool. Quarantine involves regulatory actions to prevent the spread of pests, not a direct method of reducing their numbers in-place. Release of predators uses living organisms to suppress pest populations, which is a biological control approach rather than mechanical. So, traps fit the idea of mechanical control by providing a straightforward, physical means of reducing pests without relying on chemicals or biological agents.
