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

• A. Physical Control
• B. Chemical Control
• C. Biological Control
• D. Cultural Control

Answer: (A)

Using barriers to prevent pests from entering an area is a physical control method. It relies on a tangible barrier to block access, rather than killing pests or altering their biology. Examples include screens on windows, door sweeps, seals around openings, fences, or nets that keep pests out at the boundary. Chemical control involves pesticides to kill or repel pests, biological control uses natural enemies or pathogens to reduce pests, and cultural control changes the environment or practices to lessen pest pressure. Because the focus here is prevention through a physical barrier, it is classified as Physical Control.
