A mouse has entered the apartment — what should I do? - briefly

Identify and block all gaps or holes where the rodent could enter, then deploy snap traps or humane catch‑and‑release devices while storing food in sealed containers and maintaining a clean environment. If these actions do not eliminate the problem, contact a licensed pest‑control professional.

A mouse has entered the apartment — what should I do? - in detail

When a rodent appears in a living space, act quickly to prevent damage and health risks.

First, isolate the area. Close doors to rooms where the animal has not been seen and block any obvious gaps with towels or cardboard. Turn off food sources: store all perishables in sealed containers, clean countertops, and sweep crumbs from the floor.

Next, locate possible entry points. Inspect walls, baseboards, windows, and utility openings for holes larger than a quarter‑inch. Seal gaps with steel wool, caulk, or expanding foam, because rodents can squeeze through very small spaces.

Choose a control method. Options include:

  1. Snap traps – positioned perpendicular to walls, with the trigger end facing the wall; bait with peanut butter or chocolate.
  2. Live‑catch traps – placed along known pathways; release captured animals at least ten miles away, following local regulations.
  3. Electronic traps – deliver a quick lethal shock; require batteries and regular cleaning.

Avoid glue boards; they cause prolonged suffering and are less effective for larger rodents.

After a capture, wear disposable gloves, place the rodent in a sealed bag, and discard it in an outdoor trash bin. Disinfect the trap and surrounding area with a bleach solution (1 part bleach to 9 parts water) to eliminate pathogens.

Finally, implement long‑term prevention. Keep trash cans covered, repair any water leaks, and maintain a tidy environment to reduce attractants. Schedule periodic inspections of the building’s exterior for new openings, especially after renovations or seasonal weather changes.

By following these steps, the infestation can be resolved swiftly and the risk of recurrence minimized.
