Mice are small, but the problems they cause are anything but.
Like rats, they can carry disease and pose a real risk to health, and they can do considerable damage to wiring, walls and furniture if they are allowed to breed indoors. Because a single mouse can reproduce at an alarming rate, the advice from the experts at Principal Environmental is always the same – act quickly.
Why mice multiply so fast
A mouse can produce up to eight litters a year, with between eight and twelve offspring every six weeks. That means a couple of mice can become a heavy infestation in a remarkably short time. Mice are nocturnal, so they are most active at night, and they need to chew constantly on hard materials such as timber, electrical cables and plumbing pipes to stop their teeth overgrowing. It is this constant gnawing that makes them such a risk to any property.
How do I know if I have mice?
There are a few reliable signs. Mice moving around attics, ceilings and wall cavities can create surprisingly loud scratching noises, usually most noticeable after dark. You may also spot droppings – small and shaped like grains of rice – in tucked-away places such as behind presses and cupboards.
Common signs of mice
- Scratching noises: often heard at night from attics, ceilings or wall cavities
- Odour: a distinctive stale smell, usually behind kitchen sinks, cupboards or hot-presses
- Droppings: like grains of rice – a single mouse can leave around forty droppings a day
- Nests: often found behind fridges, in boiler houses, in attic spaces and between floorboards, built from whatever material is to hand
How to prevent mice
Good housekeeping makes a real difference. Keeping spaces clean and reducing clutter gives mice fewer opportunities to nest, while storing food in sealed containers removes an easy food source. Pay particular attention to hard-to-reach spots such as behind the fridge or the back of cupboards.
It also pays to survey the outside of your property. Mice can squeeze through astonishingly small gaps, so seal any openings around external pipework, gaps under doors and cracks in walls. Use bristle strips, caulking or steel wool rather than filler or expanding foam, which mice will simply gnaw through.
When mice point to a bigger problem
Mice and rats often share the same entry points and habits, so the same proofing measures help with both. If you are seeing larger droppings, greasy smear marks along skirting boards or signs of more serious gnawing, you may be dealing with rats instead – in which case our guide to rat control and prevention is the place to start.
Looking ahead to summer pests
Rodents are a year-round concern, but as the weather warms up the focus shifts to flying insects. Businesses in hospitality, healthcare and food production rely on effective fly control and prevention to stay hygienic and compliant, while households and premises alike need to watch out for wasps. If you spot a nest, never disturb it – arrange professional wasp control and nest removal instead.
Time for action
A mouse problem rarely fixes itself, and the longer it is left, the bigger it becomes. Principal Environmental provides professional mouse control and prevention for homes and businesses across Ireland, with practical proofing advice to keep them from coming back.
