Demonstration And Research Pest Control Practice Test

Rodent-proofing is about exclusion—the goal is to block access to the building so rodents cannot enter or nest inside. This means sealing and repairing potential entry points, installing barriers like screens and door sweeps, and using durable materials to close gaps around foundations, pipes, vents, and roofs. Because rodents can squeeze through very small openings, effective proofing targets every potential route and makes the interior unattractive for nesting. When entry is prevented, infestations are less likely to start, reducing damage and disease risk without needing to rely on traps or poisons after the fact. Other measures, like washing walls to erase scent trails, or decorative deterrents, don’t stop entry, and relying solely on traps or poisons addresses a problem after it occurs rather than preventing it.
