Using barriers to prevent pests from getting into an area is an example of which type of pest management method?

• A. Biological
• B. Mechanical
• C. Genetic
• D. Regulatory

Answer: (B)

Blocking pest entry with physical barriers is a mechanical pest management approach. It relies on creating a barrier that pests cannot cross, keeping them out of the area rather than killing them or changing their biology. Examples include screens on windows, door sweeps, sealing gaps, nets, and other physical exclusion around an area. This reduces pest pressure and can lessen the need for chemicals, fitting well within an integrated pest management strategy. In contrast, biological methods use living organisms to reduce pest populations, genetic methods alter pest traits or reproduction, and regulatory methods involve laws, quarantines, or restrictions.
