Why are rats attracted to blocked drains?
Rats have lived alongside human settlements for centuries because they are opportunistic feeders. Modern drainage systems often provide everything they need to survive, including shelter, water and food.
When a drain becomes blocked, organic matter begins to accumulate. Food particles, grease and other waste remain trapped inside the pipe instead of flowing freely through the system. This creates an ideal feeding ground for rodents.
Blocked drains may also produce foul smells, indicating that waste is decomposing within the pipework. While unpleasant for people, these odours can attract rats from surrounding areas.
In many towns and cities across the United Kingdom, sewer rats already inhabit underground drainage networks. If they discover a weakness in the drainage system or detect a reliable food source, they may investigate further.
