Mice can do serious damage to a house.

How to Get Rid of Mouse Problems in the Walls

by Lisa McQuerrey

If you hear the pitter-patter of little feet or scratching sounds in your walls, or if you find mouse droppings in your home, you could have a mouse infestation inside your walls. Ignoring the problem will only lead to continued population growth that could eventually pose a health risk. Extermination and cleanup are important to fully eradicating the problem.

1 Examine baseboards, floors and walls for holes that indicate the presence of mice. Mice can work their way through very small openings. The presence of mouse droppings and gnawed drywall or trim are indications that you’ve got mice inside your walls. Mice that live in walls don’t stay there -- they come out at night to forage for food.

2 Seal up all of the small internal holes that you find. You can use a drywall caulking agent or even board up the holes with plywood. “Funnel” the mice out of your walls through the single largest hole you find by baiting the opening with peanut butter.

3 Set traps where you find mouse droppings. Snap traps are a fast and humane way to rid yourself of mice. You can also use live traps and release the mice you catch outside. Avoid poison, which can lead to dead and decaying mice in your walls, as well as being a health hazard to children and house pets. Also avoid glue traps, which are inhumane.

4 Prevent future mice infestations through regular cleaning, and by keeping food tightly stored in your cabinets and cupboards.

Items you will need

  • Traps
  • Gloves
  • Plastic bags

Tip

  • An exterminator that specializes in rodent control can be a fast and efficient way to ensure that your mice are appropriately and completely taken care of. An exterminator can also estimate the amount of damage the mice have done and advise you to take corrective action. For example, if an exterminator finds significant amounts of gnawed wires, it might be in your best interest to have an electrician evaluate the damage.

Warnings

  • Left unchecked, mice can do significant damage to a home, spreading disease and creating a nasty health hazard by leaving droppings in unsecured food.
  • Use caution in how you dispose of mice if you decide to handle extermination yourself. Wear gloves when removing dead mice from traps, and wrap them in several layers of plastic grocery bags before putting them in the trash. Handle live traps with care, carrying them by the handles so you don’t risk getting bitten by the mice. Release the mice in a rural area.
