What to do if there are mice in the attic? - briefly
Seal entry points, set snap or live traps, and place bait stations in the attic. After removal, disinfect the area and install rodent‑proof barriers to prevent re‑infestation.
What to do if there are mice in the attic? - in detail
Signs of rodent activity appear as droppings, gnaw marks, shredded insulation, or audible scurrying. Prompt identification prevents damage to structural elements and wiring.
Begin with a thorough visual inspection. Follow joists and rafters, examine insulation layers, and check vent openings, eaves, and roof penetrations. Record each potential entry point; typical gaps range from ¼ inch to 1 inch.
Seal every opening before deploying control measures. Apply steel wool or copper mesh to small cracks, then cover with caulk, expanding foam, or metal flashing. For larger gaps, install sheet metal or hardware cloth secured with screws. Ensure weather‑tight closure to block future ingress.
Select appropriate trapping devices. Snap traps provide rapid mortality, while live‑catch traps allow relocation. Place traps perpendicular to walls, with trigger end facing the wall, at least 2 feet apart. Position near known runways, behind insulation, and within 12 inches of suspected entry points.
Choose bait that attracts mice but does not compromise human safety. Peanut butter, chocolate, or dried fruit work effectively. Apply a pea‑sized amount to the trigger mechanism. Replace bait daily to maintain potency.
Remove food sources and eliminate clutter. Store pantry items in sealed containers, clean crumbs from surfaces, and relocate pet food to airtight bins. Repair any water leaks, as moisture attracts rodents.
Maintain a monitoring schedule. Check traps each morning, record captures, and reset as needed. Continue observation for at least two weeks after the last sighting to confirm eradication.
If infestation persists despite these actions, engage a licensed pest‑control professional. Experts can conduct advanced inspections, apply rodenticides safely, and offer long‑term exclusion plans.
