What preventive measure can help limit rodent entry into buildings?

Sealing cracks and openings is an effective preventive measure to limit rodent entry into buildings because it addresses potential entry points directly. Rodents, including mice and rats, can squeeze through very small openings, often as tiny as a quarter of an inch. By thoroughly inspecting and sealing gaps in walls, around windows, doors, and utility entries, you create a physical barrier that makes it difficult for rodents to enter. This method not only helps to prevent current infestations but also serves as a crucial proactive strategy to keep rodents from gaining access to the building in the future.

Maintaining a clean and tidy environment, which includes mowing lawns regularly and removing debris, may help deter rodents indirectly, but does not physically block their entry. Using scented candles or maintaining wet environments does not relate to rodent exclusion and may not effectively address the problem of rodent entry at all. Therefore, sealing cracks and openings stands out as the most practical and direct approach for limiting rodent access to structures.
