What is the maximum size of an opening a house mouse can squeeze through?

A house mouse can squeeze through an opening that is as small as 1/4 inch in diameter. This small size is significant because it reflects how adaptable and flexible the body structure of a house mouse is, allowing it to navigate through tight spaces to access food, shelter, or escape from predators. Their ability to fit through such narrow openings is one of the reasons they are prevalent in human environments, as they can easily infiltrate homes and buildings. This knowledge is crucial for pest control efforts, as it underscores the importance of sealing gaps and cracks in structures to prevent mouse infestations. Understanding this characteristic can help in implementing effective measures to deter these rodents from entering living spaces.
