Who is responsible for mouse removal in a rental apartment

In most states, the landlord is legally responsible for pest control, including mice. Mice are considered a habitability issue — meaning the apartment cannot be safely lived in while they are present. Your lease almost certainly requires the landlord to maintain the unit in habitable condition.

Your first step is to notify your landlord in writing. Email, text, or a dated letter all work. Describe what you have seen: droppings, holes, sounds in walls, or actual sightings. Include the date and location. Keep a copy. This creates a record that you reported the problem and when.

The landlord must then arrange for a licensed pest control service to inspect and treat. They pay for this — you do not. If your landlord ignores the report or delays unreasonably (usually more than a week), you have legal options that vary by state, including rent withholding or breaking the lease without penalty. Contact your local tenant rights organization or housing authority to learn what applies where you live.

Key Takeaways

  • Report mice to your landlord in writing and keep a copy, because the landlord is legally responsible for pest control in rental apartments.
  • A licensed pest control service will inspect, set traps or bait stations, and usually return for follow-up visits over two to four weeks.
  • You can reduce the chance of mice returning by sealing food in containers, removing clutter, and reporting any new entry holes to your landlord when ready.
  • If your landlord does not respond within a week, contact your local tenant rights organization, because you may have the right to withhold rent or break your lease.

What to expect from a professional pest control visit

Once your landlord arranges service, a technician will arrive to inspect the apartment. They will look for droppings, gnaw marks, entry points, and signs of nesting. They will check under sinks, behind appliances, in cabinets, and along baseboards. This inspection usually takes 30 to 60 minutes.

After inspection, the technician will place traps or bait stations. Snap traps are common and kill mice quickly. Bait stations contain poison in a tamper-resistant box so children and pets cannot access it. Some services use electronic traps. The technician will tell you where traps are placed and warn you not to touch them.

Most pest control contracts include follow-up visits every one to two weeks for four to eight weeks. The technician checks traps, removes dead mice, resets traps, and looks for new entry points or activity. You should expect to see results — fewer droppings, no new sightings — within the first two weeks. If activity continues after four weeks, tell your landlord to request a different service or approach.

Sealing entry points and preventing mice from returning

Mice can squeeze through holes the size of a dime. Common entry points are gaps around pipes under sinks, cracks in baseboards, holes where utilities enter the wall, and gaps around door frames. Your landlord is responsible for sealing these, but you can help by identifying them.

Take photos of any holes or gaps you notice and send them to your landlord with your pest control report. Point out the location: "hole in baseboard behind kitchen stove" or "gap around pipe under bathroom sink." The landlord should have the pest control service or a maintenance person seal these with steel wool, caulk, or metal flashing. Mice cannot chew through steel wool.

While treatment is underway, reduce conditions that attract mice. Store food in sealed plastic or glass containers — not cardboard boxes or open bags. Clean up crumbs and grease when ready. Remove clutter where mice can hide: piles of paper, cardboard boxes, or fabric. Take out garbage daily. These steps do not replace professional treatment, but they make the apartment less appealing to mice and speed up results.

What to do if your landlord does not respond

If your landlord does not arrange pest control within seven to ten days of your written report, you have options. The first is to send a second notice, this time by certified mail or email with read receipt. State that you reported the problem on [date], that it remains unresolved, and that you expect treatment to begin within three business days.

If the landlord still does not act, contact your local housing authority, tenant rights organization, or legal aid office. Many areas allow tenants to hire a pest control service themselves and deduct the cost from rent — but only after documenting that the landlord failed to respond. Some states allow you to break a lease without penalty if the landlord does not maintain habitability. The rules vary significantly by location, so check your local tenant rights before you act.

Document everything: dates of your reports, photos of droppings or damage, copies of emails or letters, and the names of anyone you spoke to. If you end up in a dispute with your landlord, this record protects you.

Mice in common areas versus your unit

If mice are in shared spaces — hallways, basement, laundry room, or walls between units — the landlord must still treat, but the process is different. The pest control service will treat the entire building or affected areas, not just your apartment. This takes longer because the service must coordinate access to multiple units and common spaces.

Report mice in common areas to your landlord and also to your building manager or property management company if they are different people. Mention that the problem affects shared spaces and may affect other tenants. This sometimes speeds up response because the landlord knows the issue is widespread.

If mice are entering your apartment from common areas, your landlord must still seal entry points into your unit. You are not responsible for sealing the shared wall or basement — that is the landlord's job. But you should report exactly where mice are entering: "coming through hole in wall behind refrigerator" or "entering from basement through gap in floor."

Signs that mice are gone and treatment is complete

After two to four weeks of treatment, you should see clear signs that the infestation is over. No new droppings appear. You do not hear scratching or squeaking in walls. You do not see mice or their tracks. Traps remain empty for at least one week. Food stays fresh without being chewed into.

When these signs are consistent for a week or more, the pest control service will usually declare the treatment complete and stop regular visits. Ask the technician to confirm this in writing. Keep that confirmation and any photos of sealed entry points for your records.

If you see signs of mice again within a few months, report it when ready to your landlord. Most pest control contracts include a warranty period — usually 30 to 90 days — during which the service will return and retreat at no extra cost if mice return. Your landlord should invoke this warranty on your behalf.

Frequently Asked Questions

Can I use over-the-counter traps and poison instead of calling my landlord?

You can use them temporarily to catch a single mouse, but they do not solve an infestation. If you have seen multiple mice or droppings in different areas, there are likely more mice in walls or hidden spaces that traps alone will not reach. You still need to report to your landlord so a professional can inspect and treat the whole apartment.

What if I have a pet and I am worried about poison?

Tell the pest control technician about your pet before they arrive. They can use tamper-resistant bait stations that pets cannot open, or they can use traps instead of poison. Some services offer pet-safe options. Your landlord should make sure the service knows about your pet.

Do I have to let the pest control service into my apartment?

Yes. Your lease requires you to allow the landlord and their contractors access for maintenance and pest control. Refusing entry can be grounds for eviction. If you have safety concerns about a specific technician, call the pest control company and ask for a different appointment or technician.

How long does it usually take to get rid of mice completely?

Most infestations are under control within two to four weeks of professional treatment. Mild infestations may clear in one to two weeks. Severe infestations or those in large buildings can take six to eight weeks. The timeline depends on how many mice are present, how well entry points are sealed, and how quickly the landlord arranges follow-up visits.

What if mice come back after treatment is done?

Contact your landlord when ready and mention that mice have returned. If it has been less than 90 days since treatment ended, the pest control service should return under warranty at no cost. If it has been longer, your landlord must arrange a new service. Mice returning usually means entry points were not fully sealed or new holes have opened.
