How small of an opening can mice enter buildings through?

Mice are remarkably small and agile creatures, and they can squeeze through surprisingly tight spaces. The correct choice— a quarter of an inch—reflects their capability to enter buildings through openings that may seem negligible to us. This adaptability helps them find shelter and access food, which is why it's crucial for food handlers and building managers to be vigilant about sealing any gaps.

In practical terms, ensuring that openings greater than a quarter of an inch are sealed can significantly reduce the risk of a mouse infestation. Regular inspections and maintenance can help address potential entry points, thereby enhancing food safety and protecting public health.
