Mice have entered the house—what should be done? - briefly

Seal all gaps, store food in airtight containers, and use snap or live traps to remove the rodents. Follow up with rodent‑proofing measures such as trimming vegetation, fixing screens, and maintaining cleanliness to prevent re‑infestation.

Mice have entered the house—what should be done? - in detail

Rodent intrusion in a residence requires immediate assessment and systematic action.

First, confirm the presence of mice by looking for droppings, gnaw marks, nests, or audible activity. Collect evidence in a notebook to track locations and frequency.

Next, eliminate food sources that sustain the infestation. Store all pantry items in airtight containers, clean crumbs from countertops, and empty pet dishes after each feeding. Keep garbage sealed and remove it regularly.

Seal entry points to prevent further ingress. Inspect the building envelope for gaps around pipes, vents, doors, and windows. Use steel wool, caulk, or expanding foam to close openings larger than one‑quarter inch. Repair damaged screens and weatherstripping.

Implement control measures. Choose one or more of the following, based on the severity of the problem and personal preference:

  1. Snap traps placed perpendicular to walls, with the trigger end facing the wall. Bait with peanut butter or chocolate. Check daily and dispose of captured rodents promptly.
  2. Electronic traps that deliver a lethal shock. Position similarly to snap traps; they provide rapid kill and reduce handling.
  3. Live‑capture traps, if relocation is desired. Release captured mice at least two miles from the residence, complying with local regulations.
  4. Bait stations containing anticoagulant or non‑anticoagulant rodenticides. Secure stations to prevent access by children or pets; follow label instructions precisely.

If the infestation persists after these steps, engage a licensed pest‑management professional. They can conduct a thorough inspection, apply advanced control methods, and provide a monitoring plan.

Finally, maintain a preventive routine. Conduct monthly inspections for new signs of activity, keep the home free of food debris, and periodically check that all sealed openings remain intact. Consistent vigilance reduces the likelihood of repeat incursions.
