What To Do About Rats In Wall Cavities
Hearing scratching sounds in the walls is more than just unsettling. It often means you’ve got unwanted visitors. Many homeowners contact us asking what to do about rats in wall cavities. These rodents can cause serious damage and carry harmful diseases, so fast action is essential.
Why rats choose wall cavities
Rats in wall cavities enjoy warmth, darkness and protection from predators. These hidden spaces make perfect nesting areas. Even if your home is clean, rats only need a small opening to get inside. They often enter through damaged air bricks, broken pipework or roof gaps. Rats are so well adapted to living in urban environments and using buildings for home, that it is common for rats in get inside walls.
Once inside, they make their way into wall spaces by chewing through insulation or plasterboard. Because they’re nocturnal, you’re more likely to hear them at night. You might notice scratching, gnawing or movement behind walls, especially in kitchens or loft spaces.
Rats in wall cavities cause more than just noise. They chew wires, pipes and woodwork, which can lead to costly damage. They also leave urine and droppings in hidden areas, which can cause unpleasant smells and health risks. If you’ve spotted any of these signs, don’t wait. Acting quickly prevents infestations from growing worse.
What we do to get rid of rats
We start with a thorough inspection of your property. This helps us confirm activity and identify entry points. Because rats in wall cavities are hard to reach, we use motion sensors, tracking dust and thermal imaging if needed. Once we’ve located the rats, we create a tailored plan to remove them safely and humanely.
We often place traps in lofts, under floorboards or near known runways. If we use bait stations, we follow strict UK pest control laws and ensure pets and children stay safe. Once the rats are gone, we carry out full proofing to stop them returning.
This includes sealing gaps with rodent-proof materials like wire mesh, concrete or metal plates. We also give advice on keeping areas free from food scraps or nesting materials. For example, we recommend storing food in sealed containers and checking bins are always closed.
