Why Do I Have Rats In My Walls?

Rats are present in your walls because your home and garden is now home to them. The question that needs to be asked here is "Where Have The Rats In My Wall Come From?".

How to Get Rid Of Rats In Your Cavity Walls

The rats are likely getting into your wall and ceiling cavities via the following routes:

Shallow Utilities

A frequent issue with modern properties is shallow utility points. This is the point at which the drains etc leave the building under the wall of the property.

In older properties, it is more common to see the soil pipes externally, but newer properties have them below ground due to better design and aesthetics.

The correct depth for these should be around 12 inches below ground level, but increasingly we see these points at ground level where rats quickly enter and populate the underfloor areas and cavities of the house.

Even if you have concrete floors, the earth beneath the floor will dry and subside by a few inches, creating the perfect nesting point for rats which can then eat through underfloor heating systems and other plastic water service pipes, etc.

Faulty or Disused Drains

It is unsurprising that more than 80% of rat problems in homes and businesses originate from the drains. In most cases, this activity is first noticed in the walls or ceilings of a new extension or other building improvement.

It is common to find open drains and even inspection chambers under extensions that allow rats unrestricted access into your property, and we can easily solve this.

Overhanging Trees, Hedges or Climbing Vegetation

Rats and other rodents will quickly climb along telephone wires, jump from overhanging branches and climb up climbing plants directly onto your roof where they quickly make themselves at home in the tight roof spaces of extensions and loft spaces of the main building.

Access into your loft under tiles is simple.

Other Points Of Entry Include:

Via the neighbours - in linked properties, through underfloor cavities, lofts and linked gutters.

Via open doors, windows and presents from your cat! - sometimes it will be a single rat, and no infestation exists.

Via Cellars and underfloor storage rooms.

What Are The Signs of Rats In Cavity Walls?

The very first signs are noises in the walls and sometimes in more than one place at once, indicating that many rats are present

Then comes the smell and even stains of, or actual dripping urine from or through the walls and ceilings. The next thing to happen in holes appearing in walls and ceilings, revealing that the rats are now invading your properties occupied areas.

One of the most significant disadvantages of cavity wall insulation is created when it bridges the cavity and allows rats to burrow through it directly into your loft or other areas of the building that may have been previously unaffected.

Q: What other Ways Can You Help Me?

rodent remediation proofing


The Bristol Rat Company has qualified electricians who can inspect and test your entire electrical system for faults and damage caused by rodent activity. We can also update older style electrical systems, reducing fire risks and the dangers of electrical accidents caused by electrocution from wires stripped bare by rats, squirrels and mice.


Damaged pipes like those leading into underfloor heating systems are a significant hazard to both your properties structural integrity and of course electrical injury. We have qualified Plumbers from that will quickly inspect and if required, replace or repair damaged pipes and equipment.

Drain Repairs and Digital Camera Inspections

Very often the rodent problems we see are a result of rats getting into the property through damaged, faulty or poorly designed sewer systems. When required we have the facilities and expertise to carry out a full inspection of the sewer system and drainage of the property. Where damage is found, we will carry out remediation work to protect the property.

Loft Insulation

Insulation is one of the most significant areas of contamination risk and is regularly overlooked. Rodents nest and live between layers, depositing huge quantities of droppings, urine and nesting material infested with insect pests.

We are able to undertake a highly effective decontamination processes in place to ensure insulation is quickly and effectively replaced and surrounding surfaces fully disinfected with a sophisticated product that kills, viruses, bacteria and many other types of microorganism.

We also use the Bristol Pest Control Services of WaspKill UK, who are experts in insect control to handle the fumigation of properties affected by flea, bedbug and lice infestations.


We have healthcare trained operatives, formally qualified in infection control to decontaminate an infested or contaminated environment. You can be assured that we understand infection control and how to achieve an intensive clean more than many other organisations.

Our head of infection control operations has fifteen years experience in clinical healthcare services as well as many years experience in the pest control industry - in short we are the best at what we do.


Proofing is where we put in place effective barriers preventing rodents from accessing a property or sensitive areas. We have experience in sealing cavity walls, cellars, attics, storerooms, kitchens and the list goes on. If you have rodents and don't want them getting in - then we have the expertise to help.
