Rodent Investigation

Locate Rodent Entry Through Drains

Rats are strong swimmers and can hold their breath long enough to travel through sewer pipes and into properties. Our rodent investigation service uses CCTV cameras to inspect your drainage system from the inside, identifying the specific points where rodents are getting through: broken pipes, missing drain covers, damaged interceptors, open inspection chambers, gaps around pipe penetrations and faulty toilet seals. The report we produce maps each entry point so repairs can be targeted precisely.

The engineer accesses the drain through existing manholes or cleanouts and feeds the camera through the system. We check each junction, connection and transition point along the route from your property to the main sewer. Where we find damage or openings large enough to allow rodent access, we record the location and depth. We then walk you through the footage and recommend the combination of rat flap installation, drain repairs or sealing works that will stop the problem permanently.

Finding the Source, Not Just the Symptom

Pest control treatments deal with the rodents already inside a property, but they don't stop more from entering. Our CCTV-based drain investigation finds the structural access routes that rodents are using, which is the information needed to block them permanently. We've carried out rodent investigations in properties across Dublin since 2006 and we work alongside pest controllers to provide a joined-up solution. All work is covered by our public liability insurance.

The concern most customers raise is whether finding the entry points will mean expensive excavation. In most cases it doesn't. Rat flap installation is non-invasive and can be completed in about an hour through existing access points. Where drain repairs are needed to close a broken section, we use no-dig relining where the pipe condition allows. Get in touch to book an investigation and we'll give you a clear picture of what's involved.

Rodent Investigation

Signs Rodents Are Entering via Drains

Rodents entering through drains can be hard to distinguish from rodents entering through other routes. The key indicators that suggest drain access specifically are rodent activity near drain covers or gullies, rats appearing near the toilet, and scratching or movement sounds under ground-floor areas close to drain runs.

  • Rats seen in the garden near drains or inspection chambers
  • Scratching sounds under ground-floor floors or in wall cavities near drain runs
  • Rodent droppings near drain covers or gullies
  • Gnaw marks on pipe fittings or drain covers
  • Rat sightings near the toilet base or in the bathroom
  • Previous rat problems that returned after pest control treatment
  • Property near restaurants, food businesses or commercial waste storage
