What should I do if mice live under drywall? - briefly
Locate and block all openings with steel wool, caulk, or metal mesh, then place snap or live traps inside the cavity to capture any remaining rodents. After removal, disinfect the space and consult a pest‑control professional to prevent future infestations.
What should I do if mice live under drywall? - in detail
Mice hidden behind wall panels require a systematic approach to eliminate the infestation and prevent recurrence.
First, locate the activity. Look for droppings, gnaw marks, shredded insulation, and faint scratching sounds. Use a flashlight and a mirror to inspect the edges of the drywall, baseboards, and any accessible cavities. If the space is completely sealed, create a small inspection hole in an inconspicuous spot to confirm presence.
Second, block all possible entry points. Identify gaps around pipes, vents, electrical wiring, and foundation cracks. Fill openings with steel wool, copper mesh, or expanding foam rated for pest control, then cover with caulk or cement to create a durable barrier.
Third, choose an appropriate control method. Options include:
- Snap traps positioned against the wall where activity is evident; bait with peanut butter or dried fruit for rapid capture.
- Live‑catch traps if relocation is preferred; check and release captured mice promptly, far from the property.
- Poison baits placed in tamper‑resistant stations, ensuring they are inaccessible to children and pets; follow label instructions for dosage and placement.
Deploy traps or bait stations in multiple locations within the cavity, spacing them about 10‑15 feet apart. Check traps daily, dispose of dead rodents according to local regulations, and reset as needed.
Fourth, address sanitation. Remove food sources by storing pantry items in airtight containers, cleaning crumbs and spills immediately, and sealing garbage cans. Repair any water leaks, as moisture attracts rodents and supports their nesting material.
Fifth, consider structural repair. After confirming the mice are gone, repair damaged drywall, replace compromised insulation, and repaint surfaces. Use a disinfectant to clean areas contaminated by droppings, as they can carry pathogens.
Finally, evaluate the need for professional assistance. If the infestation persists after multiple attempts, or if the cavity is difficult to access, a licensed pest‑control operator can provide advanced techniques such as ultrasonic devices, exclusion services, or targeted rodenticide applications.
By following inspection, exclusion, control, sanitation, and repair steps, the problem can be resolved efficiently and the risk of future intrusion minimized.
