Signs you have mice

The most reliable signs of mice are small dark droppings, gnaw marks, scratching noises at night and a stale, ammonia-like smell.

  • Droppings: small (3–6 mm), dark and pointed, often in cupboards, drawers and behind appliances.
  • Gnaw marks on food packaging, skirting boards, cables and pipe lagging.
  • Scratching or scurrying noises in walls, ceilings and under floors, especially at night.
  • A strong, stale, ammonia-like smell in enclosed spaces.
  • Greasy smear marks along walls and around holes.
  • Nests of shredded paper, fabric or insulation.

Why mice are a problem

Mice carry germs and disease and cause damage to the home, including gnawed wiring that can create a fire risk.

  • They contaminate food and surfaces with urine and droppings, spreading bacteria such as salmonella.
  • They gnaw constantly, damaging cables, pipes, insulation, furniture and stored belongings.
  • A pair of mice can produce dozens of young in a few months.
  • Mice fit through extremely small gaps, about the width of a pencil (6 mm).

Why do mice come into my home?

Mice want warmth and food, so they move indoors as the weather cools and settle anywhere with easy access to crumbs, pet food or stored food.

Common entry points include ventilation blocks and air bricks, gaps around pipes and cables, roof spaces, under doors and behind kitchen units. Terraced houses and blocks of flats often share voids, so mice move easily between properties.

Why do mice keep coming back?

Mice come back when entry points are left open, because poison or traps remove the current mice but new ones find the same route in.

That is why we find entry points (ventilation blocks, roof spaces and other areas) during the inspection and recommend sealing them after treatment.

Treatment methods and safety for children and pets

  • Free inspection to assess the true scale of the infestation before treating.
  • Tamper-resistant bait stations and professional traps placed safely.
  • Identifying entry points such as ventilation blocks and roof spaces.
  • Follow-up visits to check activity and remove bait or traps.
  • Proofing of entry points with steel wool, mesh, bristle strips and air-brick covers.

Is it safe for children and pets? All rodenticides are placed in locked, tamper-resistant bait boxes, or we use traps where children or pets are present. Our technicians follow the UK rodenticide stewardship code.

How to prepare for mice treatment

Good preparation makes treatment work faster. Print this checklist and tick off each step before we arrive.

  1. Store food, including pet food, in sealed containers.
  2. Clear clutter from under sinks, behind appliances and in lofts where possible.
  3. Note where you have seen droppings or heard noises, so we can target the inspection.
  4. Do not block holes before we arrive; we need to see where mice are travelling.

How long does mice treatment take?

The first visit takes about an hour. Most mouse treatments need 2–3 visits over 2–3 weeks, followed by proofing to stop them coming back.

How much does mice control cost in London?

Mice Control starts from £210 + VAT. The final price depends on:

  • Size of the property
  • Scale of the infestation
  • Number of visits
  • Whether proofing is added

We use the most effective professional products, which can cost a little more, but we believe you'll be happy with the quote. See our pricing guide or call 020 7101 4957.

Our guarantee

Our treatments are guaranteed for between 3 and 12 months, depending on the pest and the property. We confirm exactly what is covered, and for how long, when we inspect the site. Read the full terms on our guarantee page. Every job starts with a free inspection.

Mice Control FAQs

How do I know if I have mice or rats?

Mouse droppings are small (3–6 mm) and pointed; rat droppings are larger (10–20 mm) and blunt. Read our mice vs rats guide for more differences.

How long does it take to get rid of mice?

Most infestations are controlled within 2–3 weeks over 2–3 visits. Proofing stops new mice coming in.

Can mice get through small gaps?

Yes. Mice can squeeze through gaps about 6 mm wide, roughly the width of a pencil.

Is mouse poison safe with pets?

We only use bait in locked, tamper-resistant boxes, or traps where pets and children are present.

Will mice go away on their own?

Rarely. Once mice have food and warmth, they stay and breed. Acting from the first sighting is cheaper and quicker.

How do I stop mice returning?

After treatment, entry points should be sealed so new mice cannot get back in. We advise on gaps found during inspection.
