Mice are known to enter buildings through openings that are as small as:

Mice are highly agile creatures with the ability to squeeze through very small openings. They can fit through gaps that are as small as one-fourth of an inch, which is roughly the size of a pencil. This ability to enter through tiny spaces allows them to infiltrate buildings and places where food is stored, contributing to potential contamination and health hazards. Understanding this fact is crucial for food handlers and those responsible for food safety, as it emphasizes the importance of proper pest control measures, sealing gaps, and maintaining cleanliness to prevent mice and other pests from entering food preparation and storage areas. Being aware of such details enables food handlers to implement strategies to safeguard food from rodent infestations effectively.
