What should I do if a mouse runs into an apartment? - in detail

When a rodent appears inside a residence, immediate, systematic action reduces health risks and prevents recurrence.

First, secure the area. Close doors to limit movement, turn off lights in the room, and keep pets and children away. Use a flashlight to locate the animal without startling it.

Next, decide on removal method. Options include:

  1. Live capture – Place a snap‑tight trap baited with peanut butter, cheese, or chocolate. Check the trap every 15–30 minutes; release the catch outdoors at least 100 m from the building.
  2. Humane catch‑and‑release devices – Use a cage trap with similar bait. Once the mouse is inside, transport the cage to a suitable external location.
  3. Professional extermination – Contact a licensed pest‑control service for immediate removal and assessment.

After the mouse is removed, address sanitation and exclusion:

  • Sanitize all surfaces the rodent may have contacted. Use a disinfectant containing at least 70 % alcohol or a bleach solution (1 part bleach to 9 parts water). Dispose of any contaminated food or packaging.
  • Eliminate attractants. Store food in sealed containers, clean crumbs promptly, and secure garbage in tightly sealed bins.
  • Seal entry points. Inspect walls, floors, windows, and utility openings. Apply steel wool, caulk, or metal mesh to gaps larger than ¼ inch. Install door sweeps and check vent covers.
  • Set preventive traps. Deploy a few snap traps or electronic devices along walls, behind appliances, and near suspected entry routes. Replace bait regularly.

Finally, monitor the situation for at least two weeks. Record any new sightings or trap activity and adjust preventive measures accordingly. Persistent problems warrant a thorough inspection by a pest‑control specialist to identify hidden nesting sites or structural vulnerabilities.
