Signs That Mice Have Invaded Your Home

Whether you’re hearing suspicious scratching or scrambling noises in your walls, are finding black pellets in your kitchen or cellar or are finding chewed cardboard boxes in your pantry, then the likelihood is that mice have invaded your home. But there are some other questions you should ask yourself before panicking about a potential infestation, including:


  • What other signs should I look for if I think mice are in my home?
  • Where are mice likely to build their nests both in my home and in my garden?
  • What should I do if I suspect that there are mice in my home?


Signs that mice have invaded your home


Along with finding chewed cardboard boxes in places where you store food, whether it be for your family or your pets, there are several other signs you should be watching out for if you think that mice have come into your property, including the following:


Mice droppings


  • Mice droppings look like small black pellets
  • You’ll likely find a considerable number of droppings as mice can leave around 50-80 droppings each night
  • The most common places where mice droppings are found is along floorboards and outside or just inside small cracks, holes and other crevices 


Grease marks


  • You’ll likely find grease marks against floors and walls as these make up part of the rodents’ regular scurrying route
  • Grease marks will appear as dark smears


Urine mounds


  • If you have a significant mice infestation, then their urine will combine with dirt and grease and collect as small mounds
  • These mounds, or pillars as they’re often referred to, usually build up to around 2 inches high and half an inch wide


Scratching or scurrying noises 


  • Mice are most active at night, so keep an ear out for them then
  • These noises will likely be heard between partition walls, in false ceilings, cellars, lofts and even under the floorboards


Coming across a nest


  • Mice will use materials that are easy to shred to build their nests
  • You’ll likely come across a nest in the same locations as where the scurrying noises are coming from, if you’re hearing any
  • A nest can also appear under stoves and kitchen cabinets


Tracks & footprints


  • Dusty environments will make it obvious that you have a mice problem
  • Their footprints and tracks will show up far more easily in dusty or dirty areas
  • Check cellars, lofts and other unused areas throughout your home 


Strong & unpleasant smells


  • Mice have a very distinct smell as they urinate rather frequently
  • The ammonia-like smell will linger for a considerable amount of time 
  • The stronger the scent, the closer you will be to the mice and/or their nest


Finding a mouse, dead or alive


  • Finding a live mouse is concerning as they rarely inhabit a house alone
  • A dead mouse could indicate an old infestation
  • These are sure signs that there’s an existing infestation or that there was one
  • Regardless of whether you find one that has expired or not, you should look into mice extermination or mice removal from a professional firm, such as The Pest Master


Where are mice likely to nest in your home?


Mice are extremely inquisitive, agile and tiny creatures, so small in fact that they can weave their delicate skeletons through almost any crack, hole or crevice, regardless of how small it is. With this in mind, there are several places in your home where mice might see fit to build their nests and all because those locations are warm, quiet and have a food source nearby.


The most popular places where mice like to build their nests in your home include:

  • Lofts
  • Cellars
  • Eaves
  • Kitchens
  • Utility rooms
  • Cavity walls


Where are mice likely to nest outside your home?


It’s a common misconception that mice infestations only present themselves as a winter issue, but actually, mice can invade your home, either inside or out in the garden, at any time of the year. So where should you be looking outside your home?

  • Garages
  • Sheds
  • Compost bins
  • Vegetation


What should you do if you think there are mice in your home?


It’s imperative that you do not try to carry out
mice removal or mice extermination yourself. Not only will it pose a danger to yourself, but it could also put your pets and others at risk.
