Mice Treatment Information & Identification Guide
Mus musculus
The discovery of mice in your home can be surprisingly distressing - these small, seemingly harmless creatures actually pose significant health risks and can cause substantial property damage while reproducing at an alarming rate. At Pest Pro London, we understand that mice problems often start with subtle signs that gradually escalate into a serious infestation, leaving homeowners feeling overwhelmed and unsure where to turn. Despite their diminutive size, mice can contaminate far more food than they consume, spread dangerous diseases through their droppings and urine, and cause thousands of pounds in damage by gnawing through electrical cables, insulation, and structural materials. Our experienced technicians have helped countless London families eliminate mouse infestations permanently, understanding that what appears to be a minor problem can quickly become a major crisis if not addressed with professional expertise and proven elimination strategies.

Mice Treatment in London
Common Hotspots
Most affected boroughs:
Common property types:
- Victorian conversions where partition walls create extensive runway systems between units
- Restaurant kitchens with warm conditions, food debris, and multiple hiding spots behind equipment
- Student accommodation where irregular cleaning and food storage habits create perfect breeding conditions
- Older flats in mansion blocks with communal areas and shared utilities providing access routes
- Ground floor properties with direct garden access through gaps under doors and utility penetrations
- Period houses converted to multiple occupancy with shared kitchens and poor housekeeping standards
- Properties near construction sites where disturbance drives mice to seek alternative accommodation
- Homes with pets where food bowls and spillage provide consistent food sources
Seasonal Activity in London
Current Season Activity
Maximum domestic activity as mice concentrate in heated areas like boiler cupboards, kitchen appliances, and roof spaces. Nesting activity peaks with shredded materials found throughout the property.
Breeding activity increases as temperatures warm and food becomes more abundant. Pregnant females seek warm, secure nesting sites in kitchen voids and airing cupboards. Garden population starts exploring into adjacent properties.
Peak breeding period with new litters appearing every 3 weeks. Young mice begin dispersing to find new territories, often discovered in bedrooms and living areas. Outdoor populations expand, increasing pressure on surrounding homes.
Mass invasion season as outdoor temperatures drop and natural food sources diminish. Properties that never had mice suddenly experience infestations as populations seek warm indoor shelter for winter survival.
Maximum domestic activity as mice concentrate in heated areas like boiler cupboards, kitchen appliances, and roof spaces. Nesting activity peaks with shredded materials found throughout the property.
Mouse Myths vs Facts
Myth
Mice are only a problem in winter
Fact
Mice breed year-round in London buildings, producing up to 10 litters annually. Indoor infestations occur in all seasons.
Myth
A mouse can't fit through small gaps
Fact
Mice can squeeze through openings as small as 6mm (size of a pencil). Their flexible skulls allow entry through tiny cracks.
Myth
Mice are clean animals
Fact
Mice urinate constantly (50-80 times daily), leaving contamination trails that attract more mice and spread diseases.
Myth
If you don't see mice, you don't have them
Fact
Mice are nocturnal. You'll see droppings, gnaw marks, and grease smears before spotting an actual mouse. Daytime sightings indicate severe infestation.
Myth
Getting a cat will solve the problem
Fact
Cats may catch occasional mice, but won't eliminate an infestation. Mice in wall voids and ceiling spaces are inaccessible to cats.
Myth
Mice need a lot of food to survive
Fact
Mice only need 3-4 grams of food daily. They can survive on crumbs, grease residue, and food debris in kitchen appliances.
Myth
Store-bought traps are enough
Fact
DIY traps catch individual mice but don't address the breeding population or entry points. Professional treatment required for effective control.
Myth
Mice just chew on food
Fact
Mice gnaw constantly to control tooth growth. They damage electrical wiring (fire hazard), plumbing, insulation, and structural materials.
Myth
Mice are not intelligent
Fact
Mice have excellent spatial memory, learning ability, and can detect danger. They avoid traps after observing other mice getting caught.
Myth
Mice are harmless
Fact
Mice transmit over 35 diseases including Salmonella, Hantavirus, and Leptospirosis. They contaminate food surfaces and air through droppings and urine.
House Mouse vs Field Mouse
Understanding the difference between indoor and outdoor mice species is essential for effective control strategies.
House Mouse
Mus musculus
● Appearance
Grey-brown fur, cream-colored belly, large ears, pointed snout. Body: 7-10cm, tail equals body length.
● Habitat
Lives exclusively indoors in human structures. Wall voids, ceiling spaces, kitchen cabinets, behind appliances.
● Behavior
Highly territorial, establishes regular pathways. Active year-round with 5-10 litters per year (4-8 pups each).
● Infestation Risk
95% of indoor mouse infestations in London properties. Serious health and structural risks.
● Treatment Approach
Requires professional rodenticide placement, comprehensive proofing, and follow-up monitoring to eliminate breeding populations.
Field Mouse (Wood Mouse)
Apodemus sylvaticus
● Appearance
Sandy to reddish-brown fur, white belly, very large eyes and ears. Body: 8-11cm, tail longer than body.
● Habitat
Prefers outdoor environments: gardens, hedgerows, woodland areas. Occasionally enters buildings in autumn/winter seeking shelter.
● Behavior
Solitary, excellent climber and jumper. Breeding season March-October with 2-4 litters (4-7 pups each).
● Infestation Risk
Temporary visitor - Usually doesn't establish permanent indoor populations. Lower health risk than house mice.
● Treatment Approach
Focus on entry point sealing and habitat modification. Often self-resolves when outdoor conditions improve or access is blocked.
⚠️Professional Identification Required
House mice require immediate professional treatment with comprehensive proofing, while field mice often need only entry point sealing. Our pest control experts will accurately identify the species and implement the appropriate control strategy for your specific situation.
