Find where the larvae actually are, vacuum like you mean it, and treat the fibre rather than the air. Moth papers and lavender are not going to do this.
Find the larvae — under furniture, along edges, on stair treads — vacuum thoroughly and repeatedly, launder or freeze what you can, and have the affected rooms professionally treated.
Treatment is £180 for the first room and £60 per additional room. Do not waste time on the flying adults; they are not what is eating the carpet.
Larvae avoid light and disturbance. That is the whole search strategy: go wherever nobody goes.
You are looking for gritty debris, silken webbing, small cream larvae, and thinning or bare pile. Debris appears before visible bare patches, so it is the more useful early sign.
With carpet moths, vacuuming is genuinely a large part of the answer — larvae, eggs and debris are physically removable in a way that most pests are not.

What treatment adds is penetration and persistence: reaching the base of the pile, the carpet edges and beneath furniture where the larvae actually are, and remaining active as further eggs hatch.
That last part is why one-off sprays disappoint. Eggs already laid will hatch over the following weeks regardless of what you did today.
Carpet beetle larvae do very similar damage. Moth larvae are smooth, cream, and often accompanied by silk webbing or a small portable case. Carpet beetle larvae are brown, visibly bristly, and leave shed skins that look like more larvae.
The treatment is comparable, but knowing which you have is useful — and if you are unsure, a photograph with your enquiry settles it.

No. They need keratin, which means natural animal fibres. If your carpet is polypropylene and it is damaged, the cause is something else.
Not for pest reasons. Whether damaged carpet is worth keeping is a decision about how it looks.
Central heating means carpet moths breed year-round indoors. There is no season to wait out.
Something else needing attention outside? Wasp nest treatment in Harrow Weald is a £90 fixed cost with our guaranteed service.
Find where the larvae are, vacuum thoroughly and repeatedly, launder or freeze affected textiles, and have the rooms professionally treated.
They catch adult males and are useful for monitoring, but they do not control an infestation.
Not reliably against an established infestation. At best mildly deterrent inside a sealed container.
It makes no difference. Adults do not eat fabric — the larvae do.
Considerably. Larvae, eggs and debris are physically removable — but empty the vacuum into a sealed bag outside afterwards.
Yes, for smaller items. A sealed bag in a domestic freezer for a couple of weeks is effective.
No. They need keratin from natural animal fibres.
£180 for the first room and £60 for each additional room.
