If you’re hearing strange noises near your drains, noticing unpleasant smells, or suspect rats might be getting into your property, the problem could be lurking underground. Rats often infiltrate homes and commercial buildings through damaged or poorly sealed drainage systems — and unless the source is identified, infestations can return time and again.
At The Pest Company, we offer targeted CCTV Drain Surveys for rat detection, helping you get to the root of the issue and implement long-term pest control solutions.
How Rats Enter Through Drains
Rats are incredibly resourceful and can squeeze through tiny openings. When drainage systems develop cracks, dislodge joints, or remain uncapped, they become an ideal access point. Once inside, rats use the sewer network as a safe pathway, popping up within wall cavities, kitchens, bathrooms, and basements.
Common vulnerabilities include:
- Cracked or broken pipes
- Disused or redundant drain lines
- Gaps around inspection chambers or sewer connections
- Unsealed outlets that lead directly into the property
Unless these issues are identified and repaired, rodents will continue to re-enter the property — regardless of how many are removed.
Signs of Rats in Drain Pipes
Not all rat activity is immediately visible. Because they often live and move underground, infestations can go unnoticed until they become severe. Here are some common signs to watch for:
- Scratching or scurrying noises from beneath floors or near drainage areas
- Persistent foul odours, especially in kitchens or bathrooms
- Droppings near sinks, basins, or external drains
- Gnaw marks on pipes, skirting boards, or under cupboards
- Unexplained blockages or slow drainage (caused by nesting)
If you’ve noticed any of these – especially during the colder months when winter rats become more active indoors – a professional inspection is strongly recommended.
How CCTV Drain Surveys Work
While baiting and trapping rats may offer temporary relief, they don’t solve the underlying problem. A CCTV drain survey provides a comprehensive look inside your pipes to locate the entry points, assess the damage, and determine how rats are accessing the property.
Here’s how the process works:
- Rat Camera Insertion
A high-definition drain camera is inserted into the pipework, allowing our team to navigate through the drainage network. - Real-Time Inspection
We assess the condition of the pipes, joints, and connections, recording footage of any cracks, gaps, or nests. - Report & Recommendation
Once complete, we provide a detailed report and tailored solution — whether that’s sealing an opening, repairing pipework, or installing preventative measures like a rat blocker.
This approach ensures any infestation is addressed at the source discreetly, not just treated at surface level.
Long-Term Rodent Prevention
Following a CCTV drain survey, we often recommend the following steps to ensure rats don’t return:
- Sealing entry points: Using professional-grade materials to close off access.
- Installing rat blockers: One-way valves fitted into drains to prevent rats entering while allowing waste to flow out.
- Pipe repairs or relining: Fixing any structural damage that may be allowing rodent access.
- Ongoing maintenance: Periodic drain inspections can help detect issues before they escalate.
Prevention is always more cost-effective than repeated extermination. With the right solutions in place, future infestations can be avoided entirely.

✅ Case Study: Leeds Café Owner Regains Control
The Problem:
A busy café in Leeds kept experiencing rodent reinfestations despite multiple baiting treatments from other companies. Staff were frustrated, and the Environmental Health Officer had warned that a closure notice was possible.
Our Solution:
We carried out a CCTV drain survey and discovered a uncapped drain beneath the kitchen floor. This was the hidden entry point rats had been using for months.
The Fix:
- Rat flap installed to prevent future intrusions from the main sewer.
Follow-up monitoring confirmed zero further activity.
- Customer arranging for drain to be fully repaired in the coming weeks by a drainage contractor.
The Result:
The problem vanished overnight. The café team could finally focus on customers instead of pests — and appeased the EHO on the follow up visit.
