How Do Mice Get in Your Attic?
Mice are tiny, resourceful creatures that can squeeze through openings as small as a dime. If you’ve noticed scratching noises, droppings, or insulation damage in your attic, chances are, mice have found a way inside. Here’s how they typically get in:
Gaps in the Roofline – Small cracks or holes around vents, soffits, and eaves provide easy entry.
Unsealed Utility Openings – Openings around pipes, electrical wires, and HVAC lines can serve as highways for mice.
Damaged or Missing Roof Shingles – Any weak spot on your roof can become a doorway for mice.
Gaps Around Windows and Doors – Poorly sealed attic windows or gaps in fascia boards can allow entry.
Tree Branches & Vines – Mice are excellent climbers and can use overhanging branches or thick vines to reach the attic.
Chimneys & Roof Vents – Uncovered vents and chimneys can be an open invitation for rodents.
How to Keep Mice Out of Your Attic
Now that you know how they get in, here’s how to keep them out:
✅ Seal All Entry Points – Use steel wool and caulk to block small openings. Larger gaps may require metal flashing.
✅ Trim Trees & Vegetation – Keep tree limbs at least six feet away from your roof to prevent easy access.
✅ Install Vent & Chimney Covers – Mesh screens over vents and a proper chimney cap will keep rodents out.
✅ Declutter & Keep It Clean – Mice love hidden nesting spots. Keep storage areas tidy and avoid leaving food sources nearby.
✅ Use Repellents & Traps – Peppermint oil, ultrasonic repellents, or strategically placed traps can help deter mice.
✅ Call a Professional – If mice keep returning, a professional wildlife removal service can provide a permanent solution.
