How to Get Rid of Mice

Mice look for access to buildings for food and shelter. They search for easy, abundant sources of food and undisturbed areas to nest. By removing available food sources, your home or business will be less attractive to mice. You will also help to reduce food contamination risks and the spread of disease.

Mice are not fussy eaters and will seek out leftovers on worktops, possibly spreading pathogens and diseases such as Salmonella, Leptospirosis or Hantavirus, as they search for food.

Using cats or plants to get rid of mice

Getting a cat to deter mice is an old wives’ tale. Cats do instinctively hunt mice, but a pet is rarely effective mouse control.

There are also several plants that mice allegedly dislike, including peppermint, chamomile, lavender, cloves, and chilies. These could be used as a minor deterrent, but none can promise a mouse-free home or business.

It is natural to feel uncomfortable if you have mice, but there is no need to worry. This is a common problem that can be solved quickly.

Finding mice in your home or business can be very distressing. Mice are known to spread disease as they search for food and shelter.
This poses great health risks in kitchens or where children play.

Their natural and constant gnawing habit means mice can also cause great damage to your property, furnishings, and equipment.
Simple measures like mouse proofing your property can help to protect you.

Looking for common signs of mice will also help to identify a problem early and ensure quick and effective treatment.

Signs of Mice

Have you heard scratching noises or noticed an unusual smell? You may have mice in your home. Mice can remain hidden for a long time before you even begin to suspect a problem.

If you find signs of activity, our BPCA certified technicians are able to confirm the presence of mice and offer a safe, targeted treatment for your home or business.

Mice Infestation Signs

  • Droppings – 50/ 80 droppings a night, small and dark (approx. 3 – 8 mm in length), scattered randomly, check inside or on cupboard tops or along skirting.
  • Grease marks (smudges or smears) – Caused by their bodies brushing against walls, floors and skirting on regular routes, dark smears around holes or around corners.
  • Urine pillars – In established or heavy infestations, body grease, combined with dirt and urine, builds up into small mounds, up to 4cm high and 1cm wide.
  • Scratching noises – Often at night when mice are most active. Listen for noises between partition walls, under floorboards, in false ceilings, basements, and lofts.
  • Nests – Using easy to shred materials, mice then line the nest with other soft materials. Check lofts, suspended ceilings, cavity walls, under floorboards and behind fridges, under stoves and in airing cupboards.
  • Tracks (footprints) – Dusty environments such as unused lofts and basements can show up rodent tracks and tail marks. To check for activity, sprinkle flour, talcum powder or china clay and check the next day for fresh tracks.
  • Live or dead mice – Spotting a mouse during the daytime can be an indication of a heavy infestation.
  • Strong smell – Mice urinate frequently and their wee has a strong ammonia-like smell. The stronger the smell the closer you are to mice activity. This smell can linger for a long time (even after an infestation has been removed).

Dangers of Rodents

In the past century alone, more than 10 million people have died from rodent-borne diseases. Although rodents are not major threats to our everyday health, it is justified to be concerned over the potential for rodents to transmit diseases. By their very nature and design, rodents make excellent “vehicles” for harboring and rapidly transporting diseases.
