What size hole can mice typically squeeze through?

Mice are remarkably flexible and capable of contorting their bodies to fit through surprisingly small openings. Typically, a hole the size of a nickel is the approximate maximum dimension they can navigate. This is due to their skeletal structure, which allows them to compress their bodies.

Understanding this is crucial for pest control and prevention, as identifying and sealing off potential entry points can significantly reduce the likelihood of a rodent infestation. Knowing this sizing also helps in assessing damage or signs of mice presence, as the openings they leave behind can provide clear indicators of their activity. Other sizes, while they might seem plausible, exceed the typical realm of what mice can manage to fit through.
