🐭 How Small of an Opening Can Matter to a Mouse?
You might be surprised by how little space a mouse needs to enter a home.
A house mouse can squeeze through an opening approximately ¼ inch (6 mm) wide—about the width of a pencil.
As temperatures cool across Minnesota, small exterior gaps can become important access points for mice seeking shelter.
🏠 Some areas worth paying attention to include:
▪️ Foundation and wall transitions
▪️ Openings around utility pipes and cables
▪️ Garage door corners and lower seals
▪️ Gaps where exterior building materials meet
🔎 The size of an opening doesn't always reflect its importance. A gap that looks insignificant to a homeowner may still be large enough for mouse entry.
Understanding these vulnerabilities is part of identifying how rodents may be getting inside.
📌 Save this post as a reminder to pay attention to the small gaps—not just the obvious ones.
