Which of the following is not a valid category of pest control methods?

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

Answer: (B)

Pest control methods are organized around practical approaches you can apply in the field: changing the environment or practices to make it harder for pests (cultural), physically removing or blocking pests (mechanical), using living organisms or their products to suppress pests (biological), and applying pesticides (chemical). Genetic methods aren’t typically listed as a separate, everyday category in standard operator training. They involve genetic engineering or sterilization techniques that are specialized tools and often fall under broader biological or biotechnology categories rather than a standalone pest-control category you routinely select in the field. In other words, the common, field-ready categories you work with are cultural, mechanical, biological, and chemical, while genetic methods occupy a more specialized niche.
