Where They Hide in a Conversion
The bed is still the centre of it, but the building gives them more choice than a plastered room would:
- Mortar joints in exposed brick, especially where the pointing has crumbled or been left rough
- Splits and shakes in old timber beams and posts near the bed
- The joints where a new stud wall or mezzanine meets the original structure
- Gaps around exposed pipework and cable runs
- The edges of wide floorboards and the join where new flooring meets old
Check the brick and timber within a couple of metres of the bed with a torch held low, so dark spotting shows up against the surface. Our London guide on places that get missed is a good companion for this.

Open Plan Means the Room Is the Whole Flat
Where the bed sits on a platform or behind a half-height screen, there is no door to close and no separate bedroom to treat. The sofa where someone dozes in the evening is part of the same space, and so is the rug between them. In practice we usually treat the open area as one room, which affects both the plan and the price.
A mezzanine bed adds a second level. Bedbugs will use the stair treads, the balustrade fixings and the underside of the platform, so all of those are part of the job.
Heat in a High, Open Space
Heat treatment suits a conversion well, because it reaches into brick joints and timber splits a spray cannot follow. The challenge is volume. High ceilings let warm air gather at the top while the floor and the base of the walls lag behind, and thick brick soaks up a lot of heat. More equipment, fans aimed at the low corners, and time with the thermal camera along the brick and around the beams close that gap.
Tell us about anything in the space that does not like heat: artwork, instruments, records, plants, some electronics. In an open flat there is nowhere to put them inside the treated area, so they need to go out. Heat leaves nothing behind, and these buildings are shared, so a light residual at the edges and around pipe entries afterwards is normal.
Chemical in a Conversion
Chemical treatment costs less and a residual works well along skirtings, bed frames and the joints where old structure meets new. Rough brick and split timber are harder, because there are so many gaps to reach, and the course is still usually two or three visits about 10–14 days apart. Leave any repointing or filling until after treatment; sealing cracks first can trap them where the treatment reaches less well.
When you ring about a Wapping flat, tell us roughly how big the open area is, whether there is a mezzanine, and whether the brick and beams are near the bed. That shapes the quote more than the number of rooms on paper. The Tower Hamlets page has more on flats in shared buildings.
Bedbug Control Wapping — Questions
Will heat treatment damage exposed brick or old beams?
The space is brought up gradually and held, not blasted. Tell us about anything fragile, antique or recently finished so we can go through it first.
Can bedbugs live inside the brick?
Not in solid brick, but in crumbling mortar joints and cracks near the bed, which is why those are checked and treated.
Do you treat the whole flat if the bed is in an open-plan space?
Usually the whole open area, since there is no wall between the bed and the living space. Closed rooms with no signs may be left alone.
How much does it cost to treat a warehouse flat in Wapping?
Treatments start at £220. The figure depends on the size of the space and whether it is heat or chemical, and you get it on the phone before booking.
