What type of pest management strategy uses physical barriers to prevent pest entry?

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

Answer: (B)

The pest management strategy that employs physical barriers to prevent pest entry is mechanical control. This approach involves the use of tools, devices, or physical structures to block, trap, or eliminate pests. Examples include screens on windows and doors to keep insects out, fencing to deter larger pests, or traps designed to capture rodents or insects. Mechanical control is effective because it directly addresses the pest issue without relying on chemicals, promoting a safer environment and reducing potential harm to non-target organisms. This method is particularly useful in scenarios where other control strategies may be less effective or inappropriate, such as in areas where chemical use is restricted or where sensitive habitats are present.
