How can you get rid of mice in a private house’s drywall walls? - briefly
Locate and seal all openings that permit rodents to access the wall cavity, then install snap traps or tamper‑proof bait stations inside the void. If the infestation persists, engage a licensed pest‑control professional for targeted rodenticide application or localized fumigation.
How can you get rid of mice in a private house’s drywall walls? - in detail
Eliminate rodents from interior wall cavities by following a systematic approach.
First, locate all possible entry points. Inspect the exterior for gaps around utility penetrations, foundation cracks, roof eaves, and vent openings. Inside, examine the drywall seams, baseboards, and any recessed lighting fixtures. Use a flashlight and a mirror to view hidden spaces. Mark each opening with chalk or tape.
Second, seal identified gaps. Apply steel wool or copper mesh to small holes, then cover with a high‑quality silicone or polyurethane caulk. For larger openings, install sheet metal flashing or cement‑based mortar. Ensure the sealant adheres firmly and remains intact after curing.
Third, deploy control devices within the wall voids. Place snap traps or electronic kill traps at the back of the cavity, positioning them perpendicular to the mouse’s travel path. Bait with a small amount of peanut butter, sunflower seed, or dried fruit. Check traps daily, remove captured rodents, and reset devices as needed.
Fourth, consider bait stations for areas where traps are impractical. Use tamper‑resistant stations containing anticoagulant or non‑anticoagulant rodenticides. Position stations behind baseboards or inside wall cavities, ensuring they are inaccessible to children and pets. Follow label instructions for dosage and disposal.
Fifth, address any existing damage. Cut out contaminated drywall sections, dispose of them in sealed bags, and clean the surrounding area with a disinfectant solution. Replace removed panels with new drywall, sealing the joints with joint compound and tape. Apply a protective coating to the repaired surface to discourage future nesting.
Sixth, implement preventive measures. Trim vegetation and remove debris within three feet of the building to reduce shelter. Install door sweeps and weather stripping on exterior doors. Maintain a clean interior by storing food in sealed containers and promptly cleaning spills. Schedule periodic inspections to verify that seals remain effective and that no new activity is observed.
If infestation persists despite these actions, contact a licensed pest‑control professional. They can perform infrared inspections, apply advanced exclusion techniques, and ensure compliance with local regulations regarding rodent control.
