It might sound unpleasant, but one reason rats are attracted to drains around homes in Chester is food waste that ends up in the pipework. Cooking fats, especially from lamb joints, roasts, and Sunday dinners, can create the perfect food source in drainage systems.
Across Chester, Hoole, Upton, Blacon, and Saltney, we often see rodent activity linked to kitchen waste entering drains. When fats and grease are poured down the sink, they cool and stick to the inside of the pipe. Over time, they build up into thick deposits that trap other food particles.
From a rat’s perspective, that greasy build-up is basically a food source sitting inside a sheltered tunnel.
I remember a job in Handbridge where a homeowner had repeated rat sightings around the garden. When we inspected the drain system using a CCTV Drain Survey in Chester, we found a section of pipe with heavy grease build-up from cooking fats. That grease had attracted rodents, and a small crack in an old clay pipe allowed them to access the system.
🍖 Why Lamb Fat Attracts Rats
Lamb fat and other cooking fats are particularly attractive to rodents because:
- High fat content provides energy for rodents
- Grease sticks inside pipes, creating a long-term food source
- Food scraps become trapped in the grease
- Drains provide warm, sheltered tunnels for rats
Once rats start exploring a drain system, they can travel surprisingly far through pipework.

If you regularly cook roasts or fatty meats, avoid pouring fats down the sink. Let them cool and dispose of them in the bin instead. It helps prevent grease blockages and removes one of the biggest food sources for rats inside drains.
