Tiny Trespassers: Tackling House Mice Infestations

House mice (Mus musculus) are one of the most commonly encountered pests in UK homes. Despite their diminutive size, these rodents pose significant health and property risks. This article explores the characteristics, and dangers associated with house mice infestations.

Understanding House Mice

House mice are small, usually weighing around 12 to 30 grams, with a body length of 7 to 9.5 cm, excluding the tail. They possess a keen sense of hearing, taste, smell, and touch, helping them navigate and find food. House mice are primarily nocturnal and are known for their quick and agile movements.

Why Are House Mice a Concern?

  • Health Risks: Mice carry and transmit diseases such as salmonella  and hantavirus through their droppings, urine, and saliva.
  • Property Damage: With their sharp incisors, mice can gnaw through wood, plastic, and even soft metals, causing structural damages and risking electrical fires by chewing on wires.
  • Food Contamination: As scavengers, mice often search for food, contaminating stored food and preparation areas in the process.

Detecting House Mice Infestations

House mice infestations can be detected through various signs. Early detection is crucial to prevent a large-scale infestation, as mice can multiply quickly. Here are some common indicators of a mouse infestation:

  • Droppings: Mice droppings are small, dark, and rod-shaped. Look for them in secluded areas, under sinks, in drawers, or in food storage areas.
  • Urine Odour: House mice have a characteristic strong, musky odour, particularly noticeable in closed spaces.
  • Gnaw Marks: Look for small, clear-cut holes and gnaw marks on food packaging, wood, and plastics. The marks may be rough and irregular.
  • Nesting Materials: Mice use soft and fibrous materials like paper, fabric, or insulation for nesting. Finding these materials shredded or piled in hidden corners might be a sign of infestation.
  • Sounds: Listen for scratching, squeaking, or scampering noises in walls, ceilings, and floors, especially at night when mice are most active.
  • Tracks: Dusty areas may reveal tracks or tail marks. You can sprinkle flour or talc in suspected areas to better visualise their paths.
  • Live or Dead Mice: Seeing a live or dead mouse is a clear sign of infestation.
  • Pets Acting Oddly: If your pets (especially cats and dogs) are fixating on a particular area or acting restless, they may be sensing the presence of mice.
  • Damage to Stored Foods: Inspect your pantry or food storage areas for damaged packaging and contamination.

Prevention Measures

  • Seal Entry Points: Close off any small holes, cracks, or gaps that mice could use to enter your home.
  • Proper Sanitation: Keep your home clean, particularly the kitchen, to avoid attracting mice with food crumbs or spillages.
  • Storage: Store food in airtight, glass containers and dispose of any kitchen waste regularly.
