rodentproofing

Rodentproofing is the practice of preventing rodents, primarily mice and rats, from entering and living in a building. The goal is to reduce health risks, prevent damage to structures and stored goods, and minimize disease transmission.

A rodentproofing program combines sanitation, exclusion, and ongoing monitoring to create a barrier that rodents cannot breach. It emphasizes an integrated pest management approach rather than relying on traps or poisons alone.

Exclusion techniques include inspecting the exterior for gaps and openings around foundations, doors, windows, pipes, utility lines, vents, and chimneys. Seal openings with appropriate materials such as metal hardware cloth or sheet metal for larger holes, copper mesh for smaller gaps, and concrete or mortar for masonry joints. Install door sweeps and weatherstripping; cap chimneys; use vent screens and covers on attic and crawlspace openings.

Interior and sanitation: Store food in sealed containers, promptly clean up spills, manage garbage, and reduce clutter that provides hiding places. Remove wood piles, rubble, and dense vegetation near the building. Ensure drainage directs water away from the foundation. Keep basements, crawl spaces, and attics dry and well-ventilated.

Maintenance and monitoring: Regularly inspect for new gaps, chew marks, droppings, and signs of nesting. Revisit sealing after renovations. If an active infestation is present or if access points are difficult to close, professional pest control assistance may be required. Rodentproofing is most effective as part of a long-term preventive plan rather than a one-time fix.
