Why damaged drainage pipes may provide a route for rats and why pest control alone may not fix the access point.
A drain can provide a route
Rats can live in sewer networks. Where pipework or connections are damaged, they may find routes into cavities or the ground beneath a building.
Look for more than one clue
Scratching, droppings, disturbed insulation and unusual smells may indicate rodents, but none pinpoints entry via drains on its own.
Investigate possible access
If repeated rodent treatment has not resolved the issue, a drainage inspection may help identify damaged pipes or openings. A pest-control specialist may also need to assess the property.
Repair the entry point
Removing an animal is not the same as closing the route into the building. Any proposed drainage repair should be supported by evidence.
Hygiene and safety
Avoid handling droppings or sewage without appropriate precautions. Seek suitable professional advice for extensive contamination.
