£180 first room, £60 each after. And one check worth doing before you book, because with carpet beetles the source is frequently above your head rather than under your feet.
£180 for the first room and £60 for each additional room. One room £180, two £240, three £300, four £360.
Before booking: check the loft. Carpet beetles breed in old birds' nests and animal remains, and a roof-space source keeps producing beetles into the rooms below no matter how many rooms you treat.
| Rooms | Calculation | Total |
|---|---|---|
| 1 room | £180 | £180 |
| 2 rooms | £180 + £60 | £240 |
| 3 rooms | £180 + (2 × £60) | £300 |
| 4 rooms | £180 + (3 × £60) | £360 |
The source of most confusion about carpet beetles, and worth getting straight before you go looking.
| Adult beetle | Larva ('woolly bear') | |
|---|---|---|
| Appearance | Small, rounded, mottled black/brown/cream | Elongated, brown, densely bristly |
| Size | 2–4mm | Up to about 5mm |
| Where you see it | Windowsills, near light | Carpet pile, under furniture, wardrobes |
| Damages fabric? | No | Yes |
| What it eats | Pollen outdoors | Keratin — wool, silk, fur, feather |
People see the adults on a windowsill, assume a harmless beetle wandered in, and never connect them to the bare patch under the sofa.
The beetle on your windowsill is looking for a way out. The thing eating your carpet is somewhere much darker — and possibly in your loft.
This is the one thing that distinguishes a carpet beetle job from a carpet moth job, and skipping it is why people pay twice.
Carpet beetles evolved feeding on keratin in nests — feathers, dried remains, shed skin. A house with an old bird's nest in the eaves, a disused chimney with a nest in it, or a dead bird or rodent in a roof void has a self-sustaining nursery producing adults that fly down into the rooms below.
If you find something, tell us. It changes what needs doing alongside the room treatment.

View Carpet Beetle Control Harrow →Larvae moult repeatedly and leave the empty bristly skins behind. Those skins look almost exactly like larvae, which is why people report far more than are actually present.
Finding a number of shed skins is still meaningful — larvae have been developing there for some time — but do not assume every bristly thing you find is alive.
Some people react to carpet beetle larval hairs with an itchy rash that gets mistaken for bites. Carpet beetles do not bite. If someone has an unexplained rash and you have found bristly larvae, the two may be connected — a doctor can advise on the rash while we deal with the source.
Damage to a wool carpet costs far more than a treatment, and published room pricing means the decision does not need a quotation stage. A void is the practical time — and the loft is checkable without disturbing anyone.
Adults fly in from outside — they feed on pollen and are drawn to flowering plants — and lay indoors. Old birds' nests in roof spaces are the other common source.
Not for pest reasons. Treatment deals with the infestation.
Moth larvae are smooth and cream with silk webbing. Beetle larvae are brown and bristly and leave shed skins.
