How Do I Identify Black Mice Claw Marks?

Keep in mind that black mice are rodents. As with all rodents, their front teeth grow constantly, so mice must gnaw to keep them filed down. Mouse chew marks can look like furrows or lines, clusters or tiny dents.

The wood is easy to recognize by these tiny double lines. They are often found on cabinets, baseboards and rafters in homes. You can see mouse bite marks on other surfaces, such as paper or cardboard.

By gnawing on electrical wiring and PVC pipe, mice can cause serious property damage. Mice chew on pipes to get at the water. When mice gnaw on pipes, they leave rough edges.

The mice are not trying to cause damage by chewing on wires and pipes. As nocturnal, fearful animals, mice have a natural desire to chew. They prefer dark, hidden places. These are also the places where pipes and wires can be found in a house.

These scratches can also be seen in soft materials, such as wood. These scratches are caused by the tiny, sharp nails of a mouse. Near the gnaw marks, you may see oily rub marks. Naturally, mice and rats have oily fur.

They also have a habit of staying close to walls when they travel along well-traveled paths. As they move along the same route repeatedly, oils from their fur will rub off on the walls.


What Attracts Black Mice to the House?

To get rid of mice, you need to identify and eliminate the things that attract them inside. As with all living creatures, black mice who move into your house are searching for these things:
  • Shelter
  • Food
  • Water
  • Leaky faucets
  • Pipes
  • Food in the pantry
  • Pet bowls left out
  • Open garbage
  • Compost bins
  • Recycling bins

Food and food waste should be stored in tightly sealed containers so that mice cannot get inside. You should empty your pet’s food and water dishes every night since mice are active at night.

Fix any leaks and other water sources to prevent pests from being attracted to them. 


How Do I Get Rid of Black Mice in My Home?

Finding out how these pests enter your home is a big part of eliminating them. Mice can enter your house through tiny holes.

Mice can squeeze through holes as small as a pencil’s diameter. If they can find food and water, they will nest inside safe space, such as behind the fridge or inside the wall.

They will then start to breed. If you’ve ever dealt with a mouse infestation, you know how quickly the nests can grow.

  • To close off the mouse entry points, look for any gaps, holes or other openings on the exterior of your house that mice can get through.
  • The most common places to look are around vents, hose bibs and exterior doors. There should be no gaps or tears in the screens of any doors or windows.
  • Seal any holes with steel wool or caulk. 
  • To keep out mice and other pests, you can cover the openings with wire mesh.
  •  If they are damaged or have gaps, window and door screens need to be replaced.
