£180 first room, £60 each after. Carpet beetles cause the damage people blame on moths, and the larva that does it has a name you may already know.
Professional carpet beetle treatment costs £180 for the first room and £60 for each additional room. One room £180, two £240, three £300, four £360.
As with carpet moths, the adult beetle is not what damages your carpet. The larva does — the small brown bristly creature often called a woolly bear.
| Rooms treated | Calculation | Total |
|---|---|---|
| 1 room | £180 | £180 |
| 2 rooms | £180 + £60 | £240 |
| 3 rooms | £180 + (2 × £60) | £300 |
| 4 rooms | £180 + (3 × £60) | £360 |
This is the source of most confusion about carpet beetles, and it is 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, in wardrobes |
| Damages fabric? | No | Yes |
| What it eats | Pollen and nectar outdoors | Keratin — wool, silk, fur, feather |
People typically see the adults on a windowsill, assume they are a harmless beetle that wandered in, and never connect them to the bare patch appearing under the sofa.
The beetle on your windowsill is looking for a way out. The thing eating your carpet is somewhere much darker.
Carpet beetle larvae moult repeatedly and leave the empty bristly skins behind. Those skins look almost exactly like larvae, which is why people report far more larvae than are actually present.
Finding a number of shed skins is still meaningful — it means larvae have been developing there for some time — but do not assume every bristly thing you find is alive.

That loft point is worth a second look. Carpet beetles feed naturally on the keratin in feathers and animal remains, so an abandoned bird's nest in a roof space is a self-sustaining source that keeps producing beetles into the rooms below.

Carpet beetles do not bite. If someone in the household has an unexplained itchy rash and you have found bristly larvae, the two may be connected — and 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 period is the practical time to do it.
Moth larvae are smooth and cream, often with silk webbing. Beetle larvae are brown and visibly bristly, and leave shed skins. Treatment is comparable; identification is still useful.
