“If you haven’t seen the pipes, you haven’t seen the problem.”
Most people think of rats as “garden pests” or “loft dwellers.” But as a former Councilncil Pest Control Officer with 20 years on the tools, I can tell you the truth: 9 times out of 10, your rat problem is actually a plumbing problem.
If you’ve been paying for bait boxes every few months and the scratching just keeps coming back, you’re treating the symptoms, not the disease. Here is why a CCTV Drain Survey is the only way to get a 100% permanent fix.
The “Rat Highway” Beneath Your Feet
In older areas like Rainhill, Knowsley, and St Helens, we have miles of Victorian and mid-century drainage systems. Over time, these pipes crack, joints slip, or redundant junctions are left uncapped.
To a rat, a cracked drain pipe is a 5-star tunnel directly into your cavity walls and floorboards.

Why Baiting Fails
Baiting kills the rats currently in your house. But it leaves the “front door” wide open. A new family of rats will detect the pheromones of the previous residents and use the exact same pipe-break to move back in.
I’ve discussed this “Bait and Run” cycle in my previous post: Why Council Baiting Often Fails (Internal Link).
This is the cycle I see constantly:
- The Visit: Bait is laid.
- The Quiet: Rats die; scratching stops for 3 weeks.
- The Return: New rats find the entry point.
- The Cost: You pay for another call-out.

The Forensic Approach: CCTV Imaging
At North West Pest Finder, we don’t guess. We investigate.
Using specialized high-definition CCTV drain cameras, we navigate your drainage system to find the exact point of failure. Whether it’s a collapsed section of pipe or a “blind junction” from an old extension, we see it on screen in real-time. This follows the industry best practices outlined by the National Association of Drainage Contractors (External Link).
The 100% Solution
Once we find the break, we don’t just “hope” the rats stay away. We offer:
- Structural Proofing: Sealing the entry points with materials rats can’t chew.
- Drain Repairs: Fixing the “highway” so the access is gone forever.
- Block-Wide Analysis: Checking shared connections to ensure the whole terrace or semi-detached block is protected.

Stop Guessing. Start Solving.
If you are tired of the “Bait and Run” cycle and want a permanent end to the stress of rats in your home, you need a specialist who looks deeper than the loft.
Don’t just feed them. Block them.
