Carpet beetle treatment in London
The varied carpet beetle is, according to the Natural History Museum, most common in London and the southern counties. Its bristly larvae, the woolly bears, eat wool, feathers and fur and leave clean round holes with no webbing. Treatment in London usually costs £130 to £220 for a single visit and £200 to £300 for the more common two-visit course.

London and South East ranges from the Fantastic Services carpet beetle cost guide (updated 30 September 2026, including VAT), read 28 October 2026. We have no tie to that firm. A guide, not a quote. Removing old nests from a loft may be priced separately.
What a good quote covers
Ask for these six points in writing before anyone starts, so you know what you are paying for.
- Identification
- Confirmation that it is carpet beetle and which one, since the varied, the fur and the brown carpet beetle behave differently.
- The source found
- A search of lofts, eaves, chimneys and airing cupboards for the old nests or dead insects feeding the larvae.
- Rooms and surfaces
- Each room, carpet edge, floorboard gap and piece of furniture covered by the price.
- Two visits or one
- Whether a follow-up is included, and when, so larvae that hatch afterwards are dealt with.
- Your preparation
- What to vacuum, wash or freeze first, and which textiles to keep bagged until the course is over.
- Products and safety
- The insecticide used, how long to keep out, and what that means for babies, pets and fish tanks.
How carpet beetle treatment usually goes
- Before day one
Vacuum and bag
Vacuum carpet edges, floorboard gaps and under furniture thoroughly, and seal affected wool or feather items in bags.
- Day one
Find the source
The technician checks the loft, eaves and voids for nests and debris, and treats the rooms where larvae are feeding.
- Two or three weeks on
Second visit
A follow-up treats larvae that have hatched since, and checks whether any source was missed.
- The next spring
Watch the windowsills
Adults leave to feed on flowers and fly in again in spring, so a few on the sills are worth checking for, not panicking about.

How do I tell carpet beetle larvae from moth larvae?
Moth larvae are smooth and creamy with a dark head, and live under silk webbing. Woolly bears are hairy, banded brown and leave clean holes with no webbing, as the Natural History Museum explains.
Do carpet beetles bite?
No. Neither adults nor larvae bite people. Some people react to the tiny hairs on the larvae, getting an itchy rash that is easily mistaken for bites. If a rash does not settle, ask a pharmacist or GP.
Why are there carpet beetles on my windowsill?
Adult varied carpet beetles head for the light to get out and feed on pollen, so they gather at windows in spring and summer. Their eggs are laid back indoors on wool, fluff and old nests.
Where do carpet beetles come from?
Often from bird nests in lofts, eaves and chimneys, where larvae feed on feathers and debris before moving into the rooms below. Adults also fly in through open windows.
Can I get rid of carpet beetles myself?
Light problems can respond to thorough vacuuming, removing old nests, storing woollens in sealed bags and freezing small items. The Natural History Museum also lists proprietary insecticides. If larvae keep appearing, a specialist will look for the source.
How long does carpet beetle treatment take to work?
The larval stage can last many months, and the varied carpet beetle may take a year to complete its cycle indoors, so a two-visit course and a few months of vacuuming and checking are normal.
