How can I get rid of mice in drywall? - briefly
Identify and seal all cracks, gaps, and openings in the drywall and adjacent framing. Deploy snap or electronic traps inside the cavity and use a rodent‑repellent powder or ultrasonic deterrent to eliminate remaining mice and prevent re‑entry.
How can I get rid of mice in drywall? - in detail
Eliminating rodents that have taken residence in interior wall cavities requires a systematic approach. Begin with a thorough inspection to locate activity signs—droppings, gnaw marks, or nesting material—focusing on gaps around plumbing, electrical boxes, and vent openings. Mark each suspected entry point for later treatment.
Next, seal all openings larger than a quarter‑inch. Use steel wool or copper mesh backed with expanding foam, followed by cement or metal flashing for durability. Pay special attention to gaps around pipes, ducts, and where the drywall meets the foundation.
Deploy trapping devices inside the cavity. Snap traps positioned against interior walls capture mice quickly; place them perpendicular to the wall with the trigger end facing the expected travel path. For concealed areas, use glue boards or electronic traps that can be set within the cavity opening and retrieved later. Bait with high‑protein foods such as peanut butter or dried meat, refreshing it every few days.
If trapping alone proves insufficient, introduce bait stations containing anticoagulant rodenticides. Position stations in tamper‑resistant containers near active zones, ensuring they are inaccessible to children and pets. Follow label instructions strictly and monitor for signs of decline in rodent activity.
Consider repellents as a supplementary measure. Ultrasonic emitters mounted in the affected rooms create frequencies uncomfortable to rodents, while natural deterrents like peppermint oil applied to cotton balls placed near entry points can discourage re‑entry. Replace these applications regularly to maintain effectiveness.
After confirming the absence of activity for at least two weeks, remove all traps and bait stations. Repair damaged drywall sections using new sheets, applying joint compound and paint to restore the surface. Finally, implement preventive practices: keep food storage sealed, maintain a clean environment free of crumbs, and schedule periodic inspections to catch early signs of intrusion.
If infestations persist despite these steps, contact a licensed pest‑management professional. They can conduct comprehensive assessments, apply advanced exclusion techniques, and ensure compliance with local regulations regarding rodent control.
