Mouse Control London

The house mouse (Mus musculus) is London’s most commonly reported pest. Its small size — a mouse can squeeze through a gap as narrow as 6 mm, roughly the diameter of a pencil — makes it extraordinarily difficult to exclude without professional proofing. London’s dense Victorian and Edwardian terraced housing provides ideal conditions: shared party walls, interconnected roof spaces, and ageing brickwork with dozens of potential entry points in every property.

Mice contaminate food, spread disease (including hantavirus and salmonella), and cause significant damage to insulation, cables, and stored items. If you hear scratching in your walls at night or find droppings in your kitchen drawers, you are almost certainly looking at an established infestation rather than a single mouse — mice rarely travel alone. Swift, professional intervention is the only reliable solution.

Signs You Have a Mouse Problem

• Droppings: Small, dark, rice-shaped droppings (3–6 mm) in kitchen cupboards, drawers, behind the cooker, or along skirting boards
• Gnaw marks: Small gnaw marks on food packaging, wiring, pipe insulation, and wooden joists
• Nesting material: Shredded paper, insulation, or fabric in hidden spaces behind appliances, in cavity walls, or under floorboards
• Urine smell: A distinctive musky ammonia smell, particularly in enclosed spaces such as cupboards or airing cupboards
• Footprints: Fine dusty footprints or tail drag marks in less-disturbed areas — place a thin layer of flour to confirm if unsure

Treatment Process

1. Property survey: Our technician inspects the full property — kitchen, utility areas, loft, basement if present, and external walls. We identify active runs, entry points, and harbourage sites. London terraced properties often have shared infestations across multiple houses, and we will advise if this appears to be the case.
2. Treatment deployment: We place bait boxes and/or break-back traps at strategic locations based on activity evidence. For food businesses or homes with young children and pets, we discuss the most appropriate treatment method and location.
3. Follow-up visit(s): We return after 7–14 days to assess progress, refresh bait or relocate traps, and confirm the infestation is clearing. Most programmes require 2 visits; persistent infestations may need a third.
4. Proofing: Once the active infestation is resolved, we seal identified entry points. Airbricks, pipework gaps, and mortar failures in older London brickwork are the most frequent culprits. Without proofing, new mice will almost always find their way in.

Survey and first treatment visit	from £80
2-visit programme	£100–£160
3-visit programme with proofing	£150–£200

Frequently Asked Questions

How quickly can mice spread through a property? A female mouse can produce 5–10 litters per year, with 4–8 young per litter. A small infestation can become a serious problem within weeks. If you have spotted signs of mice, contact us immediately rather than waiting to see if the problem resolves itself.

Why do I keep getting mice even after treatment? Re-infestation almost always indicates unsealed entry points. Professional proofing is essential for a long-term solution. We include proofing recommendations (and where possible, proofing itself) in every treatment programme.

Can I treat mice myself? Shop-bought traps and bait can reduce numbers temporarily, but without identifying entry points and treating the full extent of the infestation, DIY methods rarely solve the problem. Professional treatment is significantly more effective and ultimately more economical.

Do I need to empty my kitchen cupboards before treatment? We will advise you before the visit. For treatments near food storage areas, it is generally advisable to remove food and contact surfaces. We will confirm exactly what preparation is needed when you book.
