Seal all gaps, remove food and nesting materials, and deploy snap traps or bait stations throughout the garage. Keep the area inspected and maintain barriers to prevent future entry.
How to get rid of mice in a garage? - in detail
Eliminating a mouse infestation from a garage requires a systematic approach that combines inspection, exclusion, sanitation, and control devices.
Begin with a thorough inspection. Identify gnaw marks, droppings, and nesting material along walls, beams, and stored items. Trace pathways to the exterior, focusing on gaps around doors, windows, vents, and utility penetrations. Record each opening that could serve as an entry point.
Seal all identified openings. Use steel wool or copper mesh to fill small cracks, then cover with caulk, expanding foam, or metal flashing. For larger gaps, install weather‑stripping, metal plates, or hardware cloth with a mesh size of no more than ¼ inch. Ensure doors close tightly and that any garage door seal is intact.
Reduce attractants inside the garage. Store food, pet feed, and birdseed in airtight containers. Remove spilled grain, crumbs, and waste promptly. Keep the floor clean, sweep regularly, and dispose of garbage in sealed bins. Eliminate standing water sources by fixing leaks and draining puddles.
Deploy control devices strategically. Place snap traps or electronic traps along walls, behind stored boxes, and near identified runways. Use a minimum of three traps per suspected activity zone, spacing them 6–12 inches apart. Bait traps with high‑protein items such as peanut butter, dried meat, or commercial rodent attractants. Check traps daily, dispose of captured rodents according to local regulations, and reset with fresh bait.
If a severe infestation persists, consider bait stations. Choose tamper‑resistant stations containing anticoagulant or non‑anticoagulant rodenticides, and position them out of reach of children and pets. Follow label instructions for placement density—generally one station per 250 square feet—and monitor consumption.
Supplement mechanical methods with repellents only as an adjunct. Apply ultrasonic devices near entry points, recognizing that efficacy varies. Use natural deterrents such as peppermint oil on cotton balls placed in corners, but do not rely on them as primary control.
Maintain a monitoring routine. Inspect traps and stations weekly, re‑seal any new gaps that appear, and keep the garage orderly. Rotate trap locations periodically to prevent habituation. Document activity levels to assess progress.
Finally, implement preventive measures to avoid re‑infestation. Keep the garage door closed when not in use, maintain exterior landscaping to reduce vegetation that shelters rodents, and schedule periodic inspections, especially after seasonal changes.
By following these steps—inspection, exclusion, sanitation, targeted trapping, and ongoing monitoring—rodent presence in a garage can be effectively eliminated and prevented.
