What term describes the practice of preventing pests from entering buildings by sealing openings?

• A. Exclusion
• B. Prevention
• C. Eradication
• D. Containment

Answer: (A)

Exclusion is the practice of keeping pests out by blocking access at the building’s entry points. By sealing openings, installing screens, door sweeps, weatherstripping, and repairing cracks around foundations, you create a physical barrier that prevents pests from entering. This direct, entry-focused approach is why it best fits the description. Prevention is a broader concept that includes exclusion but also covers sanitation and moisture control to reduce pest problems. Eradication means removing pests that are already present inside. Containment focuses on limiting the spread or movement of pests once they’re in an area.
