How can you drive mice out from under the roof? - briefly
Identify and seal every gap, vent, or crack that provides access, then place snap traps or bait stations and, if desired, use ultrasonic devices or peppermint oil as deterrents. Eliminate food sources and maintain low humidity in the attic to discourage future infestations.
How can you drive mice out from under the roof? - in detail
Rodent infestations beneath the roof structure require a systematic approach that combines exclusion, population reduction, and habitat modification.
First, locate entry points. Inspect eaves, soffits, vent covers, and any gaps around chimneys or skylights. Use a flashlight to trace mouse pathways and mark openings with chalk. Seal all cracks larger than ¼ inch using steel wool, copper mesh, or expanding foam reinforced with metal flashing. Install tight‑fitting hardware cloth over vents and gaps to prevent re‑entry.
Second, reduce the existing population. Deploy snap traps or electronic kill traps along established runways, placing bait such as peanut butter or dried fruit. Position traps perpendicular to walls, with the trigger end facing the wall, because mice travel close to surfaces. Check traps daily and dispose of captured rodents promptly. For larger infestations, consider a professional rodenticide program, ensuring bait stations are placed out of reach of children and pets and comply with local regulations.
Third, eliminate attractants. Store food in sealed containers, clean up crumbs and spills, and remove accessible compost or pet feed. Trim vegetation and tree branches that overhang the roof, creating a physical barrier that limits climbing. Maintain attic insulation by keeping it dry; moisture attracts rodents and provides nesting material.
Finally, monitor and maintain. Install motion‑activated infrared sensors or electronic deterrent devices that emit ultrasonic sound intermittently, discouraging return. Conduct quarterly inspections of the roof envelope, repairing any new openings immediately. Consistent vigilance prevents re‑infestation and protects the building’s structural integrity.
