The same insect, different buildings
A cockroach in an Eltham kitchen, one in a converted flat near Woolwich town centre and one behind a riverside food unit may be the same species, but the fix isn't identical. In a house you control the whole building; in a converted block, shared risers and warmth from neighbouring flats can be part of the story; a food business carries legal duties of its own.
Confirm what you are seeing
Cockroaches stay hidden through the day, so it's usually the evidence that shows up first, droppings resembling ground pepper, shed skins, a musty smell near warm pipework, just as near Greenwich, where the Georgian maritime core around the park and the river. Checking with a torch after dark, when they're most active, gives a clearer answer than looking in daylight, true near Kidbrooke too, where a mix of older estate housing and newer riverside-style apartment developments under the Kidbrooke.
In your own kitchen

Go methodically through the warm, enclosed spots, behind the fridge, under the sink, around the boiler, and inside the plinths under the units, whether that's near Greenwich, where the Georgian maritime core around the park and the river, or elsewhere in the borough. None of this is a reflection of housekeeping, a slow leak under the sink is enough on its own to cause it - the same pattern holds near Plumstead, where victorian terraces on rising ground.
Converted blocks and barracks buildings near Woolwich

Woolwich's converted flats and former barracks buildings sit close together, sharing warm risers and sometimes drainage. Where cockroaches seem to be moving between flats rather than starting in your own kitchen, telling neighbouring households matters, since treating only one side of a shared riser rarely settles it.
If you run a food business
Any food business is legally required, under food hygiene law, to keep proper procedures for pest control running, just as near Thamesmead, where large postwar estates built around lakes and waterways on the borough's eastern edge. Record what you find and when, keep incoming stock clear of the floor, and inspect boxes on arrival, as anyone near Woolwich will recognise, where dense converted flats and former barracks buildings. Tell us the kind of premises and roughly how big it is; let us know the type of premises and its approximate size when you get in touch, commercial jobs are always quoted individually, true near Thamesmead too, where large postwar estates built around lakes and waterways on the borough's eastern edge.
What to avoid while you wait
- Spraying at cockroaches you can see, which scatters the rest into walls and next door
- Moving boxes, appliances or furniture from an affected kitchen into clean rooms
- Leaving pet food, dirty dishes or standing water out overnight
- Bringing in second-hand appliances without checking them first
