How can you remove mice from under a house roof? - briefly
Seal all gaps and cracks in the roof and eaves, then place snap traps or live‑catch traps with appropriate bait in the affected area; follow up with rodent‑proofing measures such as mesh screening and regular inspections. Use a non‑toxic rodenticide in bait stations only if traps fail, and remove any dead mice promptly to prevent disease.
How can you remove mice from under a house roof? - in detail
Identify and block all access points. Walk the perimeter of the building, inspect eaves, soffits, vents, and any gaps larger than ¼ inch. Use steel wool, copper mesh, or expanding foam to seal openings. Install weather‑resistant flashing around vents and replace damaged siding or roofing material.
Set up a trapping system. Snap traps positioned along walls, near known runways, and close to entry holes provide immediate reduction. Bait with peanut butter, dried fruit, or small pieces of cheese. Check traps daily, dispose of captured rodents, and reset traps until activity ceases.
Deploy bait stations if the infestation is extensive. Place tamper‑proof stations in concealed locations, such as behind insulation or under joists. Use rodenticide formulations approved for indoor use, following label instructions and safety precautions. Monitor stations regularly and replenish bait as needed.
Eliminate food and shelter sources. Store grain, pet food, and waste in sealed containers. Remove debris, stacked firewood, and vegetation that touch the roofline. Keep the area under the roof clean, vacuuming droppings and nesting material with a HEPA filter to prevent disease spread.
Consider environmental modifications. Install predator‑deterrent devices, such as ultrasonic emitters, although effectiveness varies. Maintain proper ventilation to reduce humidity, which discourages nesting.
If activity persists after sealing, trapping, and baiting, engage a licensed pest‑control professional. They can conduct a thorough inspection, apply targeted treatments, and provide a long‑term management plan.
