The most common signs of rats are droppings, gnaw marks, burrows, scratching or movement noises, and smear marks along regularly used routes. Evidence you may notice includes:
Old evidence can remain long after activity has stopped, so one sign on its own does not automatically prove a current infestation. Part of the investigation is working out whether evidence is fresh and where activity is actually concentrated.
Rats and mice behave differently and are controlled differently, so correct identification comes before treatment. Useful indicators include:
No single clue is decisive. Identification should not rely on one photograph or one dropping measurement; it is based on the evidence as a whole. If mice turn out to be the cause, see mouse control.
Rats usually get into buildings through defects in the structure or gaps around services. Depending on the property, the route may be above ground, below ground, through adjoining structures or occasionally associated with the drainage system. Possible routes include:
Drainage is one possible route, not the automatic explanation. Many rat problems involve an above-ground route rather than the drains.
Not every rat problem needs the same approach, and not every property needs every step below. This is the order the investigation normally follows when the situation calls for it.
Establish what has been seen or heard, where, how often and for how long, and any treatment already tried.
Look for droppings, gnawing, runs, burrows, smear marks, nesting areas and other evidence where accessible, and judge whether it appears fresh.
Examine relevant internal areas, the external perimeter, roof void, sub-floor or grounds where reasonably accessible.
Assess building defects, service penetrations, air bricks, roofline access and other possible routes.
Identify conditions that may be supporting activity, such as accessible food, waste, water or shelter.
Use the findings to decide whether trapping, professional rodenticide use, environmental measures, monitoring, proofing advice or further investigation is appropriate.
There is no single standard treatment for every rat infestation. Treatment is selected after the inspection, based on where the activity is, how much activity there is, the type of premises and the risks on site. Depending on the site, professional rat control may involve:
Rodenticide is not used automatically. The approach is explained before treatment begins, including anything you need to do or avoid while the treatment is in place.
Professional rodent control follows an integrated pest management approach: chemical and non-chemical methods are considered according to the circumstances, and rodenticides are used only where they are justified.
Where rodenticides are required, they are selected and used according to:
Conditions differ between products, so no single rule applies to every rodenticide or every treatment. Under the UK rodenticide stewardship regime, professional-use anticoagulant rodenticides are supplied only to users who can demonstrate appropriate competence. Rodenticides carry risks, which is why they are used selectively. Where rodenticides are used, any access restrictions or precautions relevant to the treatment and property are explained.
Qualifications and professional registration are listed in the business-owner section below and on the About page.
Identifying how rats are getting in is an important part of the investigation. Treatment deals with current activity; proofing aims to close the route that allowed it. Potential defects may include:
Potential entry points found during the investigation can be explained and practical proofing recommendations provided. Small, straightforward defects may sometimes be addressed during a visit where appropriate; larger building, drainage or repair work may require a separate quotation or a specialist contractor.
Effective proofing can reduce the risk of rats re-entering through the identified route. It cannot guarantee that rats will never find another way in.
Usually not without asking first. Sealing a suspected active access point before the investigation can hide useful evidence, leave an animal trapped inside the building, or cause rats to look for another route.
If you are unsure whether an opening is currently being used, photograph it and ask before sealing it.
Repeatedly treating rats without investigating how they are entering may reduce activity temporarily without resolving the underlying access route.
Recurring activity often happens because the route in, or the conditions supporting the rats, are still there. Possible reasons include:
Recurrence does not always mean a previous treatment failed. A treatment can deal with the rats present at the time while a route or food source remains that allows new rats to arrive. That is why a recurring problem calls for investigation of the property and the access route, rather than simply repeating the same baiting.
A recent investigation in Chester CH3 identified damaged or poorly sealed pipe connections and deteriorated benching within an external drainage chamber. These defects were considered a potential route for rats to move from the drainage system towards the property.
Standing water restricted the initial CCTV inspection, so the findings did not establish a complete or confirmed entry route.
The investigation illustrates why recurring rat activity can require assessment of the building and drainage, alongside treatment. Suspected access routes need to be assessed before appropriate repairs or proofing can be recommended.
They can, but drainage is not the cause of every rat problem.
Sewers and private drainage can provide a route for rats where defects or inappropriate connections allow access towards a building – for example a cracked or displaced pipe, a disused connection that was never sealed, or a defect beneath the building.
That does not mean every rat in a kitchen, loft or garden has come from a sewer. Many problems involve above-ground routes such as damaged air bricks, gaps around services or burrows in the garden. Drainage is considered when the evidence points in that direction.
A CCTV drain survey may help where recurring internal rat activity suggests an underground or drainage route and a credible above-ground route has not been identified. Pestcontrol.me.uk carries out CCTV drain investigations as a separate specialist investigation where appropriate.
A CCTV drain survey is not automatically required for every rat infestation. If there is an obvious broken air brick, open service gap, garden burrow or other credible above-ground access route, drainage may not be the first investigation required.
A CCTV drain survey can help identify visible defects within accessible drainage that may provide or contribute to rat access. It cannot guarantee that every possible rat route will be found. Drainage repairs are building work: they are quoted separately or, where required, carried out by a drainage contractor.

Following an ongoing rat problem at a property in Garston, the drainage system was identified as a potential access route. A non-return valve was installed within the drain to help restrict rats travelling towards the property while allowing wastewater to pass.
After installation, the flow was checked to confirm operation at that time. The Google video records this installation check; it does not establish a long-term outcome for the rat problem.
A valve is not appropriate for every drainage system. Suitability and any further investigation or remedial work depend on the findings at the property.
Rats may sometimes be heard or found in lofts, wall cavities, beneath floors, behind kitchen units and around service voids.
The room where activity is heard is not necessarily where the animal entered the building. Rats can travel through voids, cavities and service routes some distance from their entry point. That is why the inspection considers routes through the structure, not simply the place where noise is heard.
Rat activity in gardens is usually linked to food, shelter and undisturbed cover. Factors that can influence activity include:
You do not necessarily have to stop feeding birds, but how and where food is provided can make a difference – for example, reducing spillage and not leaving food out overnight. Advice is given according to what is found.
Where outdoor treatment is considered, the risk to wildlife, pets and other non-target animals forms part of the assessment, and not every method is appropriate in every outdoor location.
Rats can contaminate food, stored goods and surfaces through droppings, urine and contact, and they can be associated with pathogens that affect people and animals.
Leptospirosis, which can be caught through contact with water or soil contaminated by the urine of infected animals such as rats, is one example. Not every rat carries disease, and seeing a rat does not mean anyone needs medical attention. If you have a health concern, speak to your GP or NHS 111.
In homes and food businesses alike, the practical priorities are to protect food and food-contact surfaces, clean up contamination appropriately and deal with the cause of the activity.
Rats may gnaw cables, pipes, timber, insulation and packaging. Gnawing can damage materials and services, which is another reason active infestations should be investigated. Where damage is found during an inspection, it is pointed out so that it can be assessed by the appropriate trade.
Landlords, letting agents, HMO operators and property managers usually need clear findings they can act on. Rat control in rented property can involve:
Where appropriate, findings and recommendations are provided in writing. Social housing providers can also read the current Pestcontrol.me.uk guidance on Awaab’s Law and pest-related housing hazards.
Rat activity needs prompt attention in premises such as restaurants, cafés, pubs, hotels, shops, warehouses, offices, schools and food businesses. Depending on the premises, commercial work may involve:
Commercial premises normally need a site-specific assessment and written quotation, and visits can be arranged to keep disruption to the business to a minimum where practical. Read more about commercial pest control.
Rat control may need more than one visit. The number and timing of visits depend on the property, the activity and the control programme. Follow-up visits may be used to:
Where a programme of visits is recommended, it is explained as part of the treatment plan. Additional visits are not included unless the estimate or confirmed quotation specifically states that they are.
Initial domestic rat survey and treatment costs £114–£198 including VAT (£95–£165 plus VAT), depending on the level of activity.
Each revisit costs £84 including VAT (£70 plus VAT) and is charged separately.
Most rat problems are resolved within two visits, although some need a third or further visits depending on activity and treatment response.
These are guide totals, not fixed-price packages. Each further revisit costs £84 including VAT. Drain investigations and proofing are quoted separately.

The most common signs are droppings, gnaw marks, burrows, scratching or movement noises, and smear marks along regularly used routes. Old evidence can remain after activity has stopped, so an inspection is used to judge whether activity is current.
Dropping size and shape, gnawing, footprints, access points, noises, sightings and where the activity is found all help. No single clue is decisive, so identification is based on the evidence as a whole rather than one photograph or one dropping.
Usually because the access route or the conditions supporting the rats are still there. Repeatedly treating rats without investigating how they are entering may reduce activity temporarily without resolving the underlying access route.
They can, but drainage is not the cause of every rat problem. Many rat problems involve above-ground routes such as damaged air bricks, gaps around pipes or burrows in the garden.
No. A CCTV drain survey may help where recurring internal rat activity suggests a drainage route and no credible above-ground route has been found. It can help identify potential drainage-related access routes, but it cannot guarantee that every route will be found.
The visit includes discussing the activity, inspecting the evidence and the property where reasonably accessible, looking for potential entry routes and the conditions supporting the rats, and explaining the control plan.
No. Treatment depends on the findings and may include trapping, rodenticide where appropriate, monitoring, environmental measures and proofing advice.
Rodenticides carry risks and are used only where appropriate. Where they are used, professional products are applied according to their authorised label requirements and site-specific precautions. Any relevant restrictions are explained before treatment.
It is usually better to ask first. Sealing an active hole early can hide evidence, leave a rat trapped inside or push rats to another route. If you are unsure whether an opening is in use, photograph it and ask before sealing it.
It depends on the findings, the level of activity and the control programme. Where follow-up visits are recommended, they are explained as part of the treatment plan.
Yes, where appropriate, after assessing the site and the risk to wildlife and other non-target animals.
Yes. Pestcontrol.me.uk carries out rat control for landlords, letting agents, HMOs, property managers and businesses, including investigation, treatment, written findings and follow-up where required.
