Professional mouse control and proofing in London
How To Get Rid Of Mice: The Complete UK Guide
Finding mice in your home or business can be stressful, especially when you hear scratching at night, find droppings in the kitchen, notice food packaging damage or see a mouse running along a wall.
The most effective way to get rid of mice is not simply to place poison or traps. Long-term mouse control requires identifying the activity, removing food sources, using the correct control method, finding entry points and proofing the property properly.
Key point: traps or poison may reduce activity, but proofing is what helps stop mice coming back.
Quick answer
What Is the Best Way to Get Rid of Mice?
The best way to get rid of mice is to follow a structured process: confirm the signs, identify where mice are travelling, remove food sources, use suitable control measures, avoid unsafe cleaning of droppings, find and seal entry points, monitor for fresh activity and arrange professional mouse control if mice keep returning.
1
Confirm Mouse Activity
Check droppings, scratching noises, food packaging damage, sightings, nesting material and activity behind appliances.
2
Remove Food Sources
Store food correctly, clean crumbs, manage bins and reduce feeding opportunities.
3
Use Correct Control
Use traps or professional control measures in the right places, not randomly in the room.
4
Proof the Property
Find and seal the entry points so mice cannot keep returning.
Do not ignore activity
Why You Need to Act Quickly
Mice should not be ignored. They can contaminate food areas, damage packaging, gnaw materials, nest in hidden spaces and leave droppings or urine in kitchens, cupboards, lofts, voids and behind appliances.
Mouse Droppings
Small dark droppings in kitchens, cupboards, under sinks, lofts, drawers or behind appliances.
Scratching Noises
Light scratching, rustling or scurrying sounds, especially at night.
Food Damage
Gnawed cereal boxes, rice bags, flour, pet food, snacks, bread or stored food.
Nesting Material
Shredded paper, cardboard, insulation, fabric or soft materials in hidden spaces.
Mouse evidence
Signs You Have Mice
Mouse activity is often noticed before the mouse is seen. Mice usually move along edges, behind units, inside cupboards, under floors, through voids and along hidden service routes.
Mouse Droppings
Mouse droppings are usually small, dark, seed-like or rice-grain-shaped pellets. The strongest sign of active activity is whether new droppings keep appearing after cleaning.
Scratching Noises
Mice can create light scratching, rustling or scurrying sounds from walls, ceilings, kitchen units, lofts, under floors or behind appliances.
Food Packaging Damage
Mice often gnaw through cereal boxes, rice bags, pasta packets, flour bags, pet food, snacks, chocolate, bread and stored dry food.
Nesting Material
Mice may use shredded paper, insulation, fabric, cardboard or soft materials to create nests in hidden areas.
Grease Marks and Urine Smell
Regular mouse routes can sometimes leave greasy marks. A strong smell may indicate longer-term activity or nesting.
Pet Behaviour
Cats and dogs may stare at cupboards, appliances, skirting boards or wall areas where mice are active.
Hidden harbourage
Where Mice Usually Hide
Mice prefer concealed areas close to food, warmth and shelter. In London properties, mice often travel through shared building voids, pipe routes, service ducts and gaps behind kitchen units. This is why a surface-level approach often fails.
Kitchens
Behind fridges, cookers, dishwashers, washing machines, kickboards and food cupboards.
Voids and Pipe Routes
Inside kitchen unit voids, under sinks, boxed-in pipework, risers and wall cavities.
Lofts and Storage
Loft spaces, airing cupboards, storage cupboards, under floorboards and hidden nesting areas.
Commercial Premises
Commercial kitchens, stockrooms, bin areas, service rooms and food storage spaces.
Entry points
How Do Mice Get Into Homes?
Mice can enter through very small gaps and then move through the property using hidden routes. In many London buildings, the visible room is only part of the problem — the real route may be behind units, around pipes, through risers or inside wall voids.
Gaps Around Pipes
Pipe penetrations under sinks, behind appliances, around boilers and inside kitchen cupboards are among the most common entry points.
Gaps Under Kitchen Units
Mice often move behind plinths and kickboards, making activity difficult to see until droppings appear.
Wall and Floor Gaps
Small holes around skirting boards, floorboards, service penetrations and wall junctions can allow movement between voids.
Doors and External Gaps
Gaps under doors, poorly fitted thresholds and external holes can allow mice inside.
Air Bricks and Vents
Damaged vents or unprotected air bricks can allow rodent access if not properly meshed with suitable material.
Lofts and Communal Routes
In flats and shared buildings, mice may travel through risers, ceiling voids, pipework, adjoining walls and communal service routes.
Professional method
How To Get Rid Of Mice Properly
The correct approach depends on the property, the activity level and where mice are entering. However, most successful mouse control follows the same professional logic.
1
Confirm Mouse Activity
Before treating, confirm whether you are dealing with mice, rats or another pest. Look for small droppings, light scratching, tiny gnaw marks, nesting material and sightings along wall edges.
2
Remove Food Sources
Store dry food in sealed containers, clean crumbs, keep bins closed, inspect food packets and avoid leaving pet food out overnight.
3
Use Traps Correctly
Traps should usually be placed along walls, near droppings, behind appliances, under sinks and close to known travel routes.
4
Be Careful with Poison
Rodenticides must be used responsibly, safely and according to the label. DIY poison can create risks and may fail if placement or proofing is poor.
5
Do Not Rely on Ultrasonic Repellers
Plug-in devices do not identify entry points, remove food sources, clean contamination or proof the property.
6
Clean Droppings Safely
Do not sweep or vacuum dry droppings. Use a safe wet-cleaning method or ask for professional advice where contamination is heavy.
7
Find the Entry Points
Check pipework, appliances, kitchen kickboards, skirting, floor gaps, service cupboards, risers, vents, doors and external defects.
8
Seal Gaps Properly
Use suitable rodent-resistant materials. Expanding foam alone is usually not enough because mice may gnaw through it or move around it.
What works and what does not
Traps, Poison, Ultrasonic Repellers and Cleaning
Use Traps Correctly
Traps can help reduce activity, but only if placed correctly. Poor trap placement often fails because mice normally travel along edges and hidden routes. Traps alone may not solve the infestation if mice are still entering from hidden gaps.
Be Careful with Poison
Rodenticides should be used responsibly and safely. Incorrect placement can create risks, cause odour from dead mice in inaccessible voids and still fail if entry points remain open.
Do Not Rely on Plug-ins
Ultrasonic mouse repellers should not be relied upon as the main solution. They do not remove mice, seal gaps or remove food sources.
Clean Droppings Safely
Mouse droppings should be treated as contaminated material. Do not sweep or vacuum dry droppings. Wet, disinfect, allow contact time and remove carefully.
Safe hygiene
How to Clean Mouse Droppings Safely
For small amounts on hard surfaces, use a safe wet-cleaning method. For heavy contamination, loft insulation, food areas, commercial kitchens or vulnerable occupants, professional advice is recommended.
1
Keep Children and Pets Away
Restrict access to the contaminated area before cleaning.
2
Wear Disposable Gloves
Avoid touching droppings, urine or nesting material with bare hands.
3
Do Not Sweep or Vacuum
Dry sweeping or vacuuming can disturb contaminated material.
4
Spray with Disinfectant
Wet the droppings and surrounding area and allow suitable contact time.
5
Wipe with Paper Towels
Remove wet material carefully using disposable paper towels.
6
Bag Waste and Disinfect Again
Dispose safely, disinfect surfaces again and wash hands thoroughly.
Why mice return
Why DIY Mouse Control Often Fails
Many people try traps, poison or plug-in devices and still find new droppings a few days later. This does not always mean the product did nothing. It often means the root cause was never corrected.
Hidden Entry Points
Entry points are often behind kitchen units, appliances, skirting boards, pipework or service risers.
Wrong Trap Placement
Traps placed in the open often miss the actual mouse travel route.
Weak Proofing Materials
Expanding foam alone is usually not a long-term rodent-proofing solution.
Shared Building Routes
In flats, mice may enter through communal service voids, risers or neighbouring areas.
Food Still Available
Pet food, crumbs, stock, bins or low-level food cupboards may continue attracting activity.
No Follow-Up Monitoring
Cleaning without monitoring makes it difficult to know whether activity is still present.
Misidentification
A suspected mouse issue may sometimes involve rats or another source of activity.
Building Works Left Gaps
Renovations, plumbing or kitchen installations often leave hidden service holes.
Long-term solution
Mouse Proofing: The Key to Long-Term Control
Mouse proofing is the most important part of long-term mouse control. A good proofing plan should identify and seal holes around pipes, gaps behind appliances, openings under kitchen units, floorboard gaps, skirting gaps, wall holes, vents, boiler pipes, waste pipes, service risers, communal routes and external entry points.
Proofing must be carried out carefully. Sealing visible holes without understanding the full route can leave hidden access points open or, in some cases, trap mice inside voids.
Wire Wool and Metal Mesh
Useful in some gaps where rodent-resistant reinforcement is needed.
Cement-Based Repair
Important where structural gaps require a harder, longer-lasting repair.
Rodent-Resistant Sealants
Can help seal suitable cracks, joints and service penetrations.
Kickboard and Pipe Proofing
Essential where mice are entering behind fitted kitchens or pipe routes.
Timeline and recurrence
How Long Does It Take To Get Rid Of Mice?
The time needed depends on the size of the infestation, the property layout, the entry points and whether proofing can be completed. A simple, early mouse issue may improve quickly once control measures are placed and food sources are removed.
A recurring infestation in a London flat, terraced house, restaurant or building with shared service routes may take longer because entry points and hidden routes must be found and sealed.
Can Mice Come Back After Treatment?
Yes, mice can return if entry points remain open or if new gaps appear after building works, plumbing work or kitchen installation.
The best sign of progress is not just fewer sightings. It is no new droppings, no fresh noises and no new food damage after monitoring.
By property area
How To Get Rid Of Mice by Situation
How To Get Rid Of Mice in a Kitchen
Kitchens provide food, warmth, water and hidden voids. Combine safe cleaning, food control, targeted treatment, under-unit inspection, pipe-gap sealing and monitoring.
How To Get Rid Of Mice in a Flat
Flats can be more complex because mice may travel through communal risers, pipe boxing, ceiling voids, shared walls and service cupboards.
How To Get Rid Of Mice in a Loft
Lofts may contain droppings in insulation, nesting material, scratching, chewed items, gaps around eaves or access from wall cavities.
How To Get Rid Of Mice in a Business or Restaurant
Businesses need systematic pest management, monitoring, proofing recommendations, contractor reports, staff guidance and follow-up visits.
Avoid these mistakes
What Not to Do If You Have Mice
Do Not Ignore One Mouse
Seeing one mouse may be the first visible sign of a wider hidden issue.
Do Not Only Treat One Room
Mice may be entering elsewhere and travelling through voids.
Do Not Use Expanding Foam Alone
Foam may temporarily fill a gap but is often not rodent-resistant.
Do Not Leave Pet Food Out
Pet food can be a major attractant if left out overnight.
Do Not Vacuum Droppings
Dry droppings should be disinfected first and removed safely.
Do Not Block Holes Blindly
Incorrect sealing can leave other entry points open or trap activity in voids.
Do Not Rely Only on Ultrasonic Devices
They do not remove mice, seal gaps or remove food sources.
Do Not Delay Professional Help
Recurring kitchen, flat or commercial mouse activity usually needs expert inspection.

How To Get Rid Of Mice FAQs
Helpful answers about mouse control, proofing, droppings, traps, poison, ultrasonic devices and when to call a professional.
What is the fastest way to get rid of mice?
The fastest reliable approach is to identify the activity, remove food sources, place suitable control measures in the correct locations and begin finding entry points immediately. Traps or poison alone may reduce activity, but proofing is needed to stop mice returning.
Can I get rid of mice myself?
You may reduce a small mouse issue with careful trapping, cleaning and food control. However, recurring infestations, kitchen activity, flats, rental properties and commercial premises usually need professional inspection and proofing.
Will mice leave if there is no food?
Removing food sources helps, but mice may still stay if they have shelter, warmth and access through hidden gaps. Food control should be combined with control measures and proofing.
How do mice get into a house?
Mice enter through small gaps around pipes, doors, vents, walls, floors, kitchens, service ducts and building defects.
Do ultrasonic mouse repellers work?
They should not be relied upon as the main solution. They do not identify entry points, remove food sources or proof the property.
Should I use poison for mice?
Poison must be used carefully and legally, following the label, and placed away from children, pets and non-target animals. In many cases, professional assessment is safer and more effective, especially where activity is recurring.
Why do mice keep coming back?
Mice keep coming back when entry points remain open, food is accessible, proofing is incomplete or the source is in a neighbouring area, shared building route or hidden void.
Should I vacuum mouse droppings?
No. Do not vacuum dry mouse droppings. Droppings should be disinfected first and removed safely because contamination can become airborne.
How long does it take to get rid of mice?
It depends on the infestation, property layout, entry points and whether proofing can be completed. A simple case may improve quickly, while recurring activity in flats, restaurants or older London buildings can take longer.
Can mice climb?
Yes. Mice are agile and can travel through wall voids, pipe routes, loft spaces, cupboards and service areas. This is why hidden inspection is important.
Are mice dangerous?
Mice can contaminate food and surfaces with droppings, urine and saliva, damage packaging and materials, and cause distress for occupants. Droppings should be cleaned safely and the source of activity should be addressed.
When should I call Bon Accord Pest Control?
Call if you see a mouse, find droppings, hear scratching, notice food damage, have recurring activity, cannot find entry points or need professional mouse proofing in London.
