Mice are between walls, what should I do? - briefly
Identify and block all entry points, then place snap traps or bait stations in the wall cavities. If activity persists, contact a licensed pest‑control professional for comprehensive treatment.
Mice are between walls, what should I do? - in detail
Rodents hidden in wall cavities create noise, insulation damage, and potential fire hazards. Begin by confirming activity: listen for scratching, squeaking, or gnawing, and look for droppings, grease marks, or shredded material near baseboards, vents, and outlets.
-
Identify entry points. Inspect the exterior for gaps around pipes, cables, foundation cracks, and vents. Inside, check interior walls, utility openings, and the attic for holes larger than a quarter‑inch. Seal openings with steel wool, copper mesh, or expanding foam, then cover with cement or metal flashing for durability.
-
Reduce attraction. Store food in airtight containers, clean crumbs promptly, and keep garbage sealed. Eliminate standing water by fixing leaks and using a dehumidifier in damp areas.
-
Deploy control devices. Place snap traps or electronic kill traps adjacent to suspected pathways, positioning them perpendicular to walls with the trigger end facing the rodent’s travel direction. Use bait such as peanut butter, dried fruit, or nesting material. Replace traps daily and dispose of captured animals according to local regulations.
-
Apply repellents cautiously. Ultrasonic emitters may deter activity but are not universally effective; use them as a supplemental measure, not a primary solution.
-
Consider professional extermination. If evidence indicates a large infestation, multiple access points, or damage to structural components, contact a licensed pest‑control service. Professionals can perform comprehensive inspections, employ bait stations, and apply rodenticides safely.
After removal, re‑inspect the sealed openings quarterly for a year to ensure no new breaches. Maintain a clean environment and periodic monitoring to prevent recurrence.
