Rodent Drain Investigations
Most pest controllers can put traps or bait down. TTOCS goes further, taking a recurring rat problem from the first inspection all the way to the drain repair that stops it.
When You Need a Drain Investigation
Early identification helps prevent larger problems. Common signs include:
Recurring Rats
Activity returns weeks after treatment
Internal Activity
Rats inside with no external entry point
Near Plumbing
Activity near soil stacks, sinks or WCs
Garden Activity
Burrows near manholes or drain runs
Failed Treatments
More than one contractor has treated it before
Where rats keep returning, there is almost always an unresolved route into the building. In many cases that route is a defect in the drainage system.
A rodent drain investigation combines pest control knowledge with CCTV surveying and drain repair, so one team finds and fixes the cause.
From Inspection to Repair
Every investigation follows the same path, so nothing is missed.
The investigation covers:
- Pest inspection and activity mapping
- CCTV drain survey
- Locating the defect
- Excavation, patch lining, rest bend or gully repair
- Proofing
- Monitoring
You deal with one company from start to finish.
What the Camera Finds
CCTV surveys regularly uncover defects that can’t be seen from the surface.
Typical findings:
- Displaced joints
- Cracked or collapsed pipes
- Redundant, uncapped connections
- Defective rest bends at the base of soil stacks
- Rodent activity in the pipe
Findings are explained clearly, with images from the survey where useful.
Repair and Protect
Repairs are matched to the defect and the property.
Options include:
- Patch lining (no-dig)
- Excavation and pipe replacement
- Rest bend repairs
- Gully repairs
- Non-return rat blockers
Once the repair is done, monitoring confirms the rats have gone for good.

Frequently Asked Questions
What is a rodent drain investigation?
A combined pest and drainage investigation that traces how rats are getting into a building and fixes the route.
How is this different from normal pest control?
Normal treatment deals with rats already inside. An investigation finds and repairs the route they’re using.
How long does a CCTV survey take?
Most domestic surveys are completed in a single visit.
Do you carry out the repairs?
Yes. We carry out patch lining, excavation, rest bend and gully repairs, and fit rat blockers.
Is this suitable for commercial properties?
Yes. Investigations are available for homes, landlords and commercial premises.
