What is a primary rodent exclusion measure?

• A. Sealing entry points
• B. Installing electronic traps
• C. Closing gaps around doors and utility penetrations
• D. Removing attractants

Answer: (C)

Blocking access to the structure is the main idea here. The best primary rodent exclusion step is to close gaps around doors and utility penetrations because these are the practical, frequent entry routes rodents use to get inside. Tiny openings around doors where weather-stripping wears, or where pipes and cables enter the building, are classic entry points. By sealing these gaps, you prevent new rodents from gaining entry in the first place, which is more effective as a preventive measure than trying to deal with them after they’re inside. Other options represent important strategies, but not the primary exclusion action. Installing electronic traps targets ongoing control after entry, not preventing entry. Removing attractants helps reduce appeal, but rodents can still find ways inside if there are openings. Sealing entry points is a broad idea of blocking access; focusing on gaps around doors and penetrations is the specific, most impactful way to achieve exclusion.
