What should you do if mice have infested the roof? - briefly
First, identify and seal every opening that allows rodents to access the attic. Then, deploy snap traps or engage a licensed pest‑control professional, and thoroughly clean and disinfect the area to prevent future infestations.
What should you do if mice have infested the roof? - in detail
Mice in the attic require immediate action to protect the structure and health of the building.
First, confirm activity. Look for droppings, gnaw marks, shredded insulation, and audible scurrying. Use a flashlight to trace pathways from exterior walls to the roof cavity.
Second, eliminate access. Seal cracks, gaps around vents, eaves, and roof penetrations with steel wool, copper mesh, or expanding foam rated for rodents. Install metal flashing over openings that cannot be closed permanently.
Third, reduce food and shelter. Store grain, pet food, and garbage in airtight containers. Remove debris, overgrown vegetation, and stored items near the roofline that could serve as nesting material.
Fourth, set traps. Place snap or electronic devices along established runways, near walls, and close to entry points. Use bait such as peanut butter or dried fruit. Check traps daily, dispose of captured rodents following local regulations, and reset as needed.
Fifth, consider bait stations. If the infestation is extensive, deploy tamper‑resistant stations with anticoagulant pellets, positioning them out of reach of children and pets. Monitor consumption and replace according to manufacturer instructions.
Sixth, assess damage. Inspect insulation, wiring, and structural components for chew marks or contamination. Replace compromised insulation, repair exposed wiring, and clean surfaces with a disinfectant solution to prevent disease transmission.
Seventh, engage a licensed pest‑management professional when self‑treatment fails, when the population exceeds a few individuals, or when the infestation involves hard‑to‑reach areas. Professionals can provide comprehensive sealing, targeted baiting, and ongoing monitoring.
Finally, implement long‑term prevention. Conduct quarterly inspections of the roof envelope, maintain vegetation clearance, and keep exterior lighting minimal to reduce insect activity that attracts rodents. Regular maintenance of seals and flashing will deter future incursions.
