Which statement describes regulatory pest control?

• A. Is unrelated to international trade.
• B. Only domestic pests are regulated.
• C. Pest control activities are unrestricted at ports.
• D. Airports and ocean ports are monitored by pest quarantine regulatory agencies.

Answer: (D)

Regulatory pest control is about government actions that prevent pests from entering or spreading, especially at points where goods and people cross borders. Airports and seaports are key control points where pest quarantine regulatory agencies operate, performing inspections and enforcing quarantine rules on shipments, travelers, and cargo to stop pests from hitchhiking into the country. This work helps protect agriculture, ecosystems, and international trade from pests.

The other ideas don’t fit because regulatory pest control is tied to border protection and trade safety, not to being unrelated to international trade, limiting regulation to domestic pests, or allowing port activities to be unrestricted.
