Mice are on the roof, how can I combat them? - briefly
Seal all gaps in the roof and eaves, then place snap traps or bait stations in the attic, inspecting them frequently. If the problem continues, engage a licensed pest‑control service for targeted treatment.
Mice are on the roof, how can I combat them? - in detail
Rodent activity on a roof requires immediate, systematic action. First, identify entry points by examining eaves, vent openings, and any gaps around chimneys. Use a flashlight to trace gnaw marks, droppings, or nesting material. Mark each opening with chalk for later reference.
Next, seal all discovered apertures. Apply steel‑wool or copper mesh to larger holes, then cover with heavy‑duty caulk or expanding foam. For vent covers, install metal screens that fit tightly. Ensure weather‑stripping around roof access doors is intact and replace worn sections.
Implement control measures after the structure is secured. Options include:
- Snap traps placed along walls, near known pathways, and under insulation. Bait with peanut butter, chocolate, or dried fruit.
- Live‑capture traps positioned in concealed areas; release captured animals at least two miles from the property.
- Electronic ultrasonic devices mounted on rafters; use only if supplemental to physical barriers, as efficacy varies.
- Rodenticides applied in tamper‑proof bait stations; follow label instructions and keep away from children and pets.
Maintain a clean environment to discourage re‑infestation. Remove food sources by storing birdseed, pet food, and garbage in sealed containers. Trim vegetation that contacts the roof, eliminating bridges for climbing.
If damage is extensive or the population persists despite DIY efforts, engage a licensed pest‑control professional. Certified technicians can conduct thorough inspections, apply regulated baits, and provide warranties for future protection.
Finally, schedule quarterly inspections, especially after severe weather, to verify that seals remain intact and no new activity has begun. Regular monitoring prevents minor incursions from developing into full‑scale problems.
