How can I remove mice from under a stretched ceiling? - briefly
Seal all gaps leading to the space, then place snap traps or bait stations directly beneath the ceiling panels, checking them regularly; if the infestation persists, enlist a licensed pest‑control service.
How can I remove mice from under a stretched ceiling? - in detail
Inspect the area thoroughly. Locate every opening that rodents could use to enter the cavity: gaps around light fixtures, ventilation ducts, conduit entries, and seams where the ceiling material meets walls or floor. Use a flashlight and a mirror to view hidden spots. Mark each opening with chalk or tape.
Seal all identified gaps. Apply steel wool or copper mesh to small holes, then cover with a high‑temperature silicone sealant or expanding foam designed for pest control. For larger openings, install metal flashing or hardware cloth cut to size and fasten with screws. Ensure the sealant adheres to both the ceiling membrane and the surrounding structure.
Reduce attractants inside the building. Store food in airtight containers, clean crumbs and spills promptly, and eliminate standing water. Remove clutter that could provide shelter near the ceiling perimeter.
Deploy control devices within the cavity. Options include:
- Snap traps positioned against the underside of the ceiling, baited with peanut butter or dried fruit.
- Live‑catch traps placed in concealed corners, checked and released far from the property.
- Electronic rodent repellents that emit ultrasonic waves, though efficacy varies.
If using bait, choose tamper‑proof stations to prevent access by children or pets. Replace bait regularly, monitoring for activity.
Maintain a regular inspection schedule. Check traps weekly, re‑seal any new gaps that appear due to building movement, and record signs of rodent activity such as droppings, gnaw marks, or urine stains.
When infestation persists despite these measures, contact a licensed pest‑management professional. They can perform infrared inspections, apply targeted rodenticides, and recommend structural modifications to prevent future incursions.
