£360 for four rooms. The interesting part is not the arithmetic — it is that with carpet moths, the room boundaries are set by where the carpet stops, not where the walls are.
£360 — £180 for the first room plus £60 for each of the remaining three.
As four separate jobs it would be £720. But the more important question with carpet moths is what counts as a room, because continuous carpet does not respect doorways.
| Room | Charge | Running total |
|---|---|---|
| Room 1 | £180 | £180 |
| Room 2 | £60 | £240 |
| Room 3 | £60 | £300 |
| Room 4 | £60 | £360 |
Carpet moths make room-counting less tidy than it is for other pests, because a continuous run of wool carpet does not stop at a doorway.
Hall, stairs and landing fitted as one carpet is one habitat with three names. Larvae do not travel far, but adults do, and they will lay along the whole run. Treating the landing and leaving the hall is treating half of one thing.
Ask where the carpet stops, not where the room stops. That is your treatment area.
In most four-room jobs, at least one of the rooms is a circulation space rather than a room people sit in — which is exactly where undisturbed carpet accumulates.
