Final answer:
To prevent rodents from burrowing into buildings, remove debris and vegetation, seal cracks and openings in foundations, and regularly inspect and repair any structural damage to deny entry.
Step-by-step explanation:
The question asks about how to prevent rodents from burrowing into buildings through decaying masonry or cracks in the foundation. To address this issue:
- Remove debris and vegetation around the building to eliminate potential hiding and nesting spots for rodents.
- Seal up any cracks or openings in the building's foundation with appropriate materials to deny entry to rodents.
- Regularly inspect the property for signs of decay or damage that might attract or provide access to rodents and repair these issues promptly.
Using chemical repellents, bait stations, or motion-activated lights may offer some benefits, but these strategies do not directly address the issue of structural weaknesses that permit entry.
