What should you do if mice have infested the attic? - briefly
Identify and seal every opening through which rodents enter the loft. Then set snap or live traps with appropriate bait, and if the issue continues, hire a licensed pest‑control service to eradicate the infestation and sanitize the space.
What should you do if mice have infested the attic? - in detail
Mice in the attic create health risks, structural damage, and noise. Address the problem systematically to eliminate the infestation and prevent recurrence.
First, confirm activity. Look for droppings, gnaw marks, shredded insulation, and rustling sounds, especially at night. Use a flashlight to inspect corners, ducts, and joist spaces. Document findings to guide treatment.
Next, secure the entry points. Walk the exterior of the house, focusing on roof eaves, soffits, vents, and gaps around pipes. Seal openings larger than ¼ inch with steel wool, copper mesh, or cement‑based caulk. Install metal flashing over larger cracks to deter chewing.
Then, choose a control method. Options include:
- Snap traps – steel or wooden devices placed perpendicular to walls, baited with peanut butter or dried fruit. Position at least 10 inches apart, near walls and travel routes.
- Electronic traps – battery‑powered units delivering a lethal shock; require fewer placements and allow easy disposal.
- Live‑catch traps – humane cages that capture rodents for release far from the property; ensure local regulations permit relocation.
- Rodenticides – professional application of anticoagulant baits in tamper‑resistant stations; recommended only for severe infestations and must follow safety guidelines.
Deploy traps in the evening, when mice are most active, and check them daily. Remove dead specimens promptly, wearing gloves and a mask to avoid disease exposure. Dispose of carcasses in sealed bags according to local waste regulations.
After removal, clean the attic thoroughly. Vacuum droppings and urine‑stained debris, then disinfect surfaces with a solution of 1 part bleach to 9 parts water. Allow the area to dry completely before reinstalling insulation or storage items.
Finally, implement preventive measures. Keep food sources sealed inside the home, avoid leaving pet food outdoors, and maintain a tidy yard to reduce shelter. Schedule regular inspections—at least twice yearly—to detect new activity early. If signs reappear, repeat the sealing and trapping cycle or consult a licensed pest‑control professional for integrated pest management.
