£360 for four rooms. Carpet beetles spread more widely than moths, and there is a structural reason for that worth understanding before you decide on a room count.
Four rooms is £360 — £180 for the first room plus £60 for each of the remaining three.
Treated as four separate jobs it would be £720. Carpet beetles are more likely than moths to need a multi-room approach, because the adults fly and distribute eggs across a whole floor rather than staying put.
| Room | Charge | Running total |
|---|---|---|
| Room 1 (first room) | £180 | £180 |
| Room 2 | £60 | £240 |
| Room 3 | £60 | £300 |
| Room 4 | £60 | £360 |
Both pests damage the same materials, but they distribute differently, and it changes the sensible room count.
Carpet moth adults are weak fliers that tend to stay near where they emerged. Carpet beetle adults fly properly. They are drawn to light and to flowering plants outdoors, they move around the house, and they lay eggs across multiple rooms.
A carpet moth problem tends to be where you found it. A carpet beetle problem tends to be wherever the beetles have flown, which is usually a whole floor.
That is why beetle jobs more often run to three or four rooms while moth jobs cluster at one or two.
There is a second reason beetle jobs go wider, and it is the one people miss entirely.
Carpet beetles feed naturally on keratin from feathers and animal remains. An old bird's nest in a roof space, in an eaves void, or in a disused chimney is a self-sustaining breeding site that keeps producing adults, which then fly down into the rooms below.
If you have beetles in several upstairs rooms and cannot work out why, that is the first thing to consider. Treating four bedrooms while a nest continues producing beetles above them is not a plan that ends well.

A whole-floor beetle problem in a let usually turns up at changeover, and a void period is the right time — every room accessible, wardrobes empty, and the loft checkable without disturbing anyone.

If carpeted in wool, yes — and on a beetle job it matters, because a landing connects the bedrooms the adults are flying between.
Then removing it is part of the answer. Tell us what you suspect and we will advise on what is needed alongside the room treatment.

Very possibly. Old birds' nests are a self-sustaining breeding site that keeps producing beetles into the rooms below.
