Finding droppings, chewed packaging, or nesting material in a garage can be unsettling. Mice can squeeze through small gaps and often stay close to sheltered places where food and water are available. Start by looking for the conditions that are drawing them in, then address those conditions instead of relying on a single repellent.
Quick plan: Protect yourself while inspecting and cleaning, remove food and clutter, close likely entry points with durable materials, and monitor for fresh signs. If activity persists or the affected area is extensive, arrange a professional inspection.
Look for signs of mouse activity
Check along walls, behind stored items, near the garage door, and around pipes or utility openings. Common signs include small dark droppings, gnaw marks, shredded paper or fabric, damaged food packages, and scratching sounds. Avoid touching droppings or nests with bare hands.
Clean up safely
Before cleaning, keep children and pets away and ventilate the area if practical. Wear disposable gloves. Do not sweep or vacuum droppings and nesting debris while dry, since this can put contaminated particles into the air. Wet the material with an appropriate disinfectant according to its label, allow the stated contact time, then wipe it up and dispose of it in a sealed bag. Wash gloved hands before removing the gloves, then wash your hands.
If there is a large amount of droppings, a dead rodent, or contamination in an enclosed or hard-to-reach space, do not disturb it; seek appropriate professional help and follow local public-health guidance.
Remove food and hiding places
- Move birdseed, pet food, grass seed, and other dry goods into sturdy containers with tight-fitting lids.
- Clean food spills and crumbs, and avoid leaving pet food or water in the garage overnight.
- Use bins with secure lids for rubbish and remove waste regularly.
- Reduce clutter, especially cardboard piles, fabric, and other materials mice can use for nesting.
- Keep stored items off the floor where possible and leave space to inspect along walls.
Find and seal entry points
Inspect the bottom and sides of the garage door, corners, vents, foundation edges, and gaps around cables or pipes. Look for daylight, gnawing, or rub marks. Repair door seals and use rodent-resistant materials suited to each gap; soft foam alone may be chewed through. Maintain ventilation and do not block a vent or alter a fire-rated assembly when sealing openings.
Choose control methods carefully
Repellents and strong scents are not a reliable way to remove mice from a garage. If using a trap, follow its instructions and place it where children, pets, and non-target animals cannot reach it. Avoid loose poison bait or improvised methods: they can expose pets and wildlife and may leave rodents in inaccessible places. If you are unsure which approach is appropriate, ask a pest-control professional.
Monitor and prevent a return
After cleanup and repairs, check the garage regularly for new droppings, gnawing, or damaged packages. Keep food sealed, rubbish covered, and storage organised. Continued signs may mean a hidden entry point or nesting area remains, so reassess the space rather than simply adding more repellents.
When to call a professional
Consider an inspection if you keep finding fresh signs, hear activity inside walls or ceilings, cannot identify how mice are getting in, or are uncomfortable cleaning the affected area. A professional can help locate access points and recommend a targeted plan for your property.

Frequently asked questions
Will peppermint oil get rid of mice in my garage?
No scent is a dependable substitute for removing attractants and sealing entry points. The smell can fade, and mice may continue to use other parts of the garage.
Should I use poison in the garage?
Rodent poisons can pose risks to children, pets, and wildlife. Do not use loose or improvised bait. If considering any pesticide, follow its label exactly and seek professional advice about safer, suitable options.
Why do mice keep returning?
They may still have access to food, shelter, or an opening into the building. Check door seals and gaps around utilities, keep stored food secure, and monitor for fresh evidence.
