How To Get Rid Of Rats: Professional Rat Removal Guide
Rats are one of the most serious pest problems a home or business can face. They can enter through drains, damaged pipework, gaps around walls, broken air bricks, subfloor voids, loft spaces, kitchens, basements, gardens and neighbouring properties.
If you want to know how to get rid of rats properly, the answer is not simply “put down poison”. A reliable rat control plan must identify the source, locate entry points, assess drains, control the active infestation, proof the property and clean contaminated areas safely.
Quick answer: the best way to get rid of rats is to combine inspection, targeted control, drain checks, rodent proofing, hygiene cleaning and prevention.
Quick answer
What Is the Best Way to Get Rid of Rats?
The best rat control is a complete process. Killing visible rats is not enough if the entry route remains open or the drainage problem is still active.
Confirm Rat Activity
Use droppings, gnaw marks, smear marks, noises, footprints, odour, sightings or drain evidence.
Find Entry Points
Check gaps, vents, pipes, cavity walls, drains, manholes, garden burrows and building defects.
Remove Food Sources
Secure food, pet food, bird seed, bins, waste, compost and water sources.
Use Targeted Control
Use professional baiting, trapping, monitoring or drain investigation where appropriate.
Inspect Drains
If rats are coming from below ground, manholes, drain runs and soil pipes may need checking.
Proof the Property
Seal entry points with rodent-resistant materials once the activity and routes are understood.
Clean Contamination
Remove droppings, urine and nesting material safely after control.
Monitor After Treatment
Confirm that no new droppings, noises or bait take are occurring.
Why rats matter
Why Rats Are a Serious Problem
Health and Hygiene Risks
Rats can contaminate areas with urine, droppings, fur, nesting material and bacteria, especially in kitchens and food areas.
Property Damage
Rats can gnaw electrical cables, pipes, insulation, timber, plasterboard, food packaging and soft proofing materials.
Recurring Infestations
If food, shelter and access remain available, the problem can continue or return after basic treatment.
Rat signs
How Do You Know If You Have Rats?
Rat infestations are often confirmed by physical evidence rather than sightings alone. Rats are usually active at night and may avoid open areas when people are present.
Rat Droppings
Larger than mouse droppings, often found under kitchen units, in lofts, behind appliances, near pipework or around outdoor burrows.
Scratching Noises
Rats may be heard in walls, under floors, in ceilings, lofts, basements, pipe boxing or around drains.
Gnaw Marks
Rats gnaw timber, plastic, cables, insulation, air bricks, skirting boards, pipe boxing and food packaging.
Smear Marks
Greasy fur can leave dark smudge marks along walls, pipes, beams, skirting boards and entry holes.
Footprints and Tail Marks
Dusty lofts, basements and plant rooms may show footprints or tail drag marks.
Burrows and Odour
Outdoor burrows and a persistent ammonia-like smell can suggest longer-term rat activity.
Correct identification
Rats or Mice? Why Correct Identification Matters
Rats and mice require different control strategies. Treating a rat infestation as if it were mice can waste time and allow the problem to continue.
Signs More Likely to Suggest Rats
- Larger droppings
- Louder scratching or thudding noises
- Stronger urine smell
- Larger gnaw marks
- Outdoor burrows
- Drain or manhole activity
- Damage to air bricks or pipe openings
Signs More Likely to Suggest Mice
- Smaller droppings
- Lighter scratching sounds
- Activity inside kitchens and cupboards
- Smaller entry gaps
- Droppings scattered in many small areas
- Less obvious outdoor burrowing
Source of activity
Where Do Rats Come From?
Rats usually enter properties because they have found food, water, shelter, warmth, nesting material, structural gaps, drainage defects or poor waste storage.
Rats from Drains
In London, rats are frequently linked to drainage systems, defective pipework, inspection chambers, soil pipes and external gullies.
Rats from Gardens
Bird seed, compost, pet food, fallen fruit, open bins, decking, sheds and dense vegetation can attract rats.
Neighbouring Properties
Rats may originate from neighbouring gardens, restaurants, bin stores, building works, basements or communal drains.
Building Defects
Broken air bricks, pipe gaps, wall holes, damaged vents and service ducts can give rats access.
Immediate action
What To Do Immediately If You Think You Have Rats
1
Do Not Panic
Rats can be controlled, but the process needs to be systematic. Panic often leads to poor decisions.
2
Do Not Touch Droppings
Rat droppings, urine and contaminated dust should be handled carefully and never with bare hands.
3
Take Photos of Evidence
Photograph droppings, holes, gnaw marks, smear marks, burrows, damage and suspected entry points.
4
Remove Easy Food Sources
Store food securely and remove accessible waste, pet food, bird seed, compost and open rubbish bags.
5
Do Not Seal Every Hole Immediately
If rats are still inside, sealing holes too early may trap them within walls, floors or ceilings.
6
Arrange a Professional Inspection
If you have droppings, noises, gnawing, sightings or drain concerns, professional advice is the safest next step.
Avoid these mistakes
What Not To Do When Trying To Get Rid Of Rats
Do Not Rely on Poison Alone
Poison may reduce activity, but it does not show where rats are entering or stop future access.
Do Not Use Rodenticide Carelessly
Rodenticides must be used safely, responsibly and according to the product label.
Do Not Block Holes with Foam Only
Rats can gnaw through expanding foam, soft filler and weak materials.
Do Not Ignore Drains
If rats are entering from drains, internal proofing alone may not solve the issue.
Do Not Trap Rats Inside
Sealing entry points too early can cause noise, odour, dead rats and further damage.
Do Not Leave Contamination
Droppings, urine and nesting material may need safe removal and disinfection.

Professional method
How To Get Rid Of Rats Properly
A professional rat control plan should be built around investigation, control and prevention. The aim is not only to remove the current rats, but to understand why they are present and stop the same route being used again.
- Confirm the species and activity level
- Identify entry points
- Remove food, water and harbourage
- Use targeted control methods
- Inspect drains and manholes where relevant
- Proof the property
- Clean and disinfect contaminated areas
- Monitor and prevent recurrence
Step-by-step
Professional Rat Removal Process
1
Confirm the Species
Assess droppings, sounds, gnaw marks, smear marks, burrows, sightings and activity routes.
2
Identify Entry Points
Check drains, pipe holes, broken air bricks, utility gaps, cavity walls, subfloor voids and garden burrows.
3
Remove Attractants
Improve bins, food storage, garden hygiene, water sources, commercial waste and harbourage.
4
Apply Targeted Control
Use suitable baiting, trapping, monitoring, camera checks, external control points or discreet internal measures.
5
Inspect Drains
Where relevant, check manholes, drain runs, soil pipes, inspection chambers and external gullies.
6
Proof and Monitor
Seal entry points with rodent-resistant materials, clean contamination and monitor follow-up evidence.
Common rat problems
Rats in the House, Kitchen, Loft, Walls, Garden and Drains
Rats in the House
Internal rat activity may involve kitchens, wall cavities, underfloor spaces, lofts, basements, bathrooms, pipe boxing or utility rooms.
Rats in the Kitchen
Kitchens are high-risk because rats are attracted to food, warmth, water and pipe routes behind appliances and under units.
Rats in the Loft
Lofts can show droppings in insulation, chewed insulation, scratching above ceilings, gnawed cables and nesting material.
Rats in Walls or Under Floors
Hidden rat activity may cause scratching, gnawing, odour and repeated noises near pipe boxing, walls or floor voids.
Rats in the Garden
Garden rat activity is common where there are bins, bird feeders, compost, decking, sheds, clutter or burrows.
Rats from Drains and Sewers
Drain-related rat problems can be persistent and may require manhole checks, CCTV survey, rat blockers or drainage repair.
Long-term prevention
Rat Proofing: Why It Is Essential
Rat proofing is the difference between temporary control and long-term prevention. Killing rats without closing entry points often leads to recurring problems because new rats can enter through the same route.
Proofing should be done after proper inspection, not guessed. If holes are sealed before the infestation is controlled, rats may be trapped inside.
Seal Pipe Holes
Pipe penetrations under sinks, behind appliances and through external walls should be sealed properly.
Mesh Air Bricks
Broken or open air bricks may need durable rodent-resistant mesh.
Repair Brickwork
Damaged walls, gaps and broken masonry can provide access into cavities.
Install Rat Blockers
Where drains are suitable, a rat blocker can help prevent rats moving from sewers into the property drainage route.
Hygiene and aftercare
Rat Droppings, Urine and Cleaning
Rat droppings and urine should be treated as contaminated material. Do not sweep dry droppings, as this can disturb contaminated dust. Droppings should be removed using safe methods, appropriate protection and correct hygiene procedures.
Professional droppings removal and disinfection is recommended where there are many droppings, urine odour, food-area contamination, loft contamination or vulnerable occupants.
Dead Rats and Bad Smells
A dead rat inside a wall, ceiling, underfloor void or inaccessible area can create a strong smell. Signs may include sudden odour, flies appearing indoors, smell from one wall or ceiling area, recent baiting nearby, or pets reacting to a specific area.
If a dead rat is accessible, it should be removed safely. If it is inaccessible, odour management and monitoring may be needed.

Frequently Asked Questions
These are the most common questions people ask when trying to get rid of rats properly.
What is the fastest way to get rid of rats?
The fastest reliable method is professional inspection, targeted control, entry-point identification and proofing. Killing visible rats is not enough if more rats can enter through the same route.
Can I get rid of rats myself?
You may reduce activity by removing food, sealing waste and improving hygiene, but established rat infestations often require professional control because entry points, drains and hidden voids must be identified.
What attracts rats to a house?
Rats are attracted by food, water, shelter, warmth, waste, bird seed, compost, pet food, damaged drains, gaps around pipes and building defects.
How do rats get into homes?
Rats can enter through drains, gaps around pipes, broken air bricks, holes in walls, subfloor voids, basements, cavity walls, roofline gaps, damaged vents and open doors.
Are rats dangerous?
Rats can contaminate areas with droppings and urine, damage property, gnaw cables and spread disease. Rat activity should be dealt with promptly, especially in kitchens, food areas and properties with vulnerable occupants.
Do rats come from drains?
Yes, rats can enter properties through defective drains, broken pipework, open connections or damaged inspection chambers. A drain inspection or rat blocker may be needed in recurring cases.
Should I block rat holes straight away?
Not always. If rats are still inside, blocking holes too early can trap them in walls, floors or ceilings. Proofing should be part of a planned control process.
Will poison get rid of rats permanently?
Poison may reduce activity, but it will not prevent new rats entering if entry points remain open. Long-term control usually requires proofing and prevention.
What should I do if I find rat droppings?
Do not touch droppings with bare hands and avoid sweeping dry droppings. Take photos, keep children and pets away, and arrange professional advice if there are multiple droppings, urine smell, food-area contamination or ongoing activity.
How long does rat treatment take?
It depends on the infestation level, entry points, drains, food sources and proofing requirements. Some cases improve quickly, while complex infestations involving drains, neighbours or hidden voids may require follow-up and monitoring.
Do rats go away on their own?
Usually not if food, shelter and access remain available. Activity may reduce temporarily, but rats can return if the source of the problem is not addressed.
When should I call a pest controller?
Call a pest controller if you see rats, hear scratching, find droppings, notice gnaw marks, suspect drain activity, find burrows, smell urine, or have repeated activity after DIY attempts.
