Inspection-led drain investigations to identify and stop rodent ingress at source
Recurring rat problems are rarely solved at surface level alone. In many cases, rodents are accessing properties through defects within the drainage system — entering unseen and bypassing traditional proofing or baiting measures.
At Pest Shield, our CCTV drain surveys are carried out specifically for pest control purposes, allowing us to identify how rodents are entering a property and recommend targeted, permanent solutions.
Rats are highly adapted to drainage systems and will exploit even minor defects to gain access to buildings. During inspections, we commonly find:
cracked or displaced pipe joints
redundant or abandoned drain lines
damaged benching within inspection chambers
uncapped or poorly sealed connections
Without identifying these access routes, repeated treatments often address symptoms rather than the cause.
Unlike general drainage surveys, our CCTV inspections are carried out with rodent behaviour and access routes in mind. This allows us to:
identify points where rats are entering or exiting the system
assess whether defects are actively being used by rodents
distinguish between historic defects and live ingress routes
gather evidence to support further remedial works
The aim is not simply to record defects, but to establish whether they are relevant to the pest problem being experienced.
Our pest control drain surveys may reveal:
cracks, gaps or displaced joints used as entry points
open or redundant branch lines acting as hidden access routes
collapsed or damaged sections harbouring rodents
evidence of rodent movement within the system
Findings are documented clearly to support informed decision-making.
Following the survey, you receive a clear digital report, which may include:
video footage from the inspection
still images of identified defects
written explanation of findings
recommendations for corrective action
This evidence can be used to support remedial works, third-party involvement or discussions with insurers, landlords or local authorities where relevant.
Where defects are identified and confirmed as relevant to pest ingress, we may recommend corrective measures such as:
installation of stainless steel non-return valves
repair or rebuilding of damaged benching within inspection chambers
sealing or blocking of redundant drain lines
All recommendations are based on survey findings and discussed before any work is undertaken.
A CCTV drain survey may be recommended where:
rat activity persists despite surface-level control
no obvious external entry points are identified
rodents are sighted in kitchens, bathrooms or lower floors
infestations repeatedly return after treatment
properties have older or complex drainage systems
In many cases, identifying and addressing drainage access is the key to resolving long-term issues.
We carry out pest control CCTV drain surveys across Newcastle, Sunderland, Durham, Gateshead and the wider North East for domestic and commercial clients.
If you’re experiencing recurring rat problems and suspect drainage may be involved, an inspection allows us to assess whether a CCTV drain survey is appropriate.
