Where Lewisham's Rats Come From
Drain faults on Forest Hill's steep streets
The Victorian terraces climbing towards Forest Hill sit on drainage that has rarely been fully replaced since it was first laid, and the steeper gradient here means pipe joints take more strain over the decades than they would on flatter ground. A cracked run under the street lets rats move from the sewer into the space beneath a house, and from there into cellars and floor voids with nothing visible outdoors to explain it.
Gardens near Ladywell Fields and the Ravensbourne
Terraced housing near Ladywell Fields and the River Ravensbourne gives rats an above-ground alternative to the drains, with gardens backing onto open ground offering compost bins, shed bases and cover along the riverbank itself. This pattern is a different picture from the drainage faults further up the hill, so it helps to tell us whether your garden backs onto the fields or the river when you call.
Signs to Look For
- Dark, tapered droppings roughly 1–2cm long, often in small groups
- Greasy smear marks along skirting boards, pipes and the edges of holes
- Gnawing on wood, plastic, food packaging or cables
- Scratching in ceilings, walls or under the floor, mostly at night
- Burrows a few centimetres across in soil, under paving or beside a shed
- A stale, ammonia-like smell in cupboards or under the stairs
Stopping Lewisham's Rats Coming Back
Whether the route is a drain fault or a riverside garden, closing it off matters as much as dealing with the rats already inside.
