What is the minimum size opening that a mouse can squeeze through?

Mice have a remarkable ability to squeeze through tight spaces due to their flexible skeletons. The minimum size opening that a mouse can fit through is approximately 1/4 inch. This small size allows them to access a variety of environments and can pose challenges in controlling their entry into structures. Knowing this size is crucial for effective pest management strategies, as it assists in identifying gaps and openings in buildings where mice may enter. Understanding this fact can help homeowners and pest control professionals take appropriate measures to seal potential entry points and prevent infestations.
