Signs of Mice Infestation

Although not as popular as rats in Hong Kong, your home or business premises could provide an ideal location for mice infestation. Once inside your property, mice prefer to keep hidden during the day. Identifying a potential infestation through signs of activity is often a lot easier than trying to spot an actual mouse, hence getting professional treatment at the earliest sign can greatly help to reduce the length of time needed to effectively control an infestation.

Signs of Mice Activity

Finding typical signs of mice, such as droppings, could indicate an active infestation in your home or business.

  • Mouse droppings - 50/80 droppings a night, small and dark (approx. 3 - 8 mm in length), scattered randomly. Look for droppings particularly along walls, in cupboards or under sinks.

  • Grease marks (smudges or smears) - This is caused by mice fur constantly brushing against walls, floors and skirting on regular routes. You may find 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 - People often report hearing unusual scratching noises at night when mice are most active. Listen for noises between partition walls, under floorboards, in false ceilings, basements and lofts.

  • Nests - Mice use easy to shred materials, such as newspaper and fabrics, together with other soft materials to line their nest. Check lofts, suspended ceilings, cavity walls, under floorboards and behind fridges, under stoves and in airing cupboards. Nests will often contain young mice.

  • 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 smell may be very strong near the main site of activity or in enclosed spaces. This smell can linger for a long time (even after an infestation has been removed).
