Hand removal, traps, barriers, and repellents are examples of which type of control?

• A. Cultural controls
• B. Chemical controls
• C. Mechanical and physical controls
• D. Biological controls

Answer: (C)

Mechanical and physical controls rely on directly manipulating the pest or its access to the turf rather than using toxins. Hand removal physically takes pests out of the area. Traps capture them. Barriers create a physical obstacle that pests can’t cross. Repellents deter pests from the treated area or resource by behavior or perception, not by killing them with a pesticide. These methods change pest pressure through actions and barriers, fitting this category. Cultural controls adjust the environment to be less favorable to pests, chemical controls use pesticides to kill or suppress, and biological controls rely on natural enemies.
