Why Timing Beats Thoroughness Here
Carpet moth damage is cumulative and it does not reverse. Every month an infestation runs is more feeding in the same place, and on a wool carpet the cost crosses the cost of treatment quickly.
In an owner-occupied house somebody notices eventually because they move furniture for their own reasons. In a let property nobody moves anything for a year, and then everybody moves everything at once, on the day it becomes a dispute.
The single most useful habit. Look under one heavy thing every few months. Not the whole house — one wardrobe, one bed, one sofa, rotating. That is the entire early-warning system and it takes about two minutes.
Point One: Check-In
This is the inspection that decides everything later, and it is the one most commonly skipped for exactly the parts that matter.
- Look at the carpet UNDER any furniture supplied with the property — beds, wardrobes, sofas — and photograph it
- Look along the carpet edge against the skirting in every room
- Look at the base and back corners of fitted wardrobes
- Check the stairs at the outer ends of the treads
- Photograph anything you find, and anything you do not, with dates
- Get it into the inventory in writing rather than as a verbal mention
An inventory that records the condition of the open floor and not what is under the furniture says almost nothing about carpet moths, which is precisely where the argument lands twelve months later.
Point Two: During the Tenancy
Two signals are worth acting on immediately rather than waiting to see whether they pass.
- Small moths near the floor. Not around a lamp — low down, running rather than flying, in the same room more than once
- Anything that looks like thinning where the carpet was previously covered
If either appears, move one piece of furniture and look. Then report it in writing, dated, whether or not you find anything. A dated email from month four is worth a great deal at month twelve, to whichever side of this you are on.
Point Three: Before Check-Out, Not At It
The worst version of this problem is discovering it on the day the inventory clerk does. At that point there is no time to treat, no time to compare it with the check-in record, and no room to do anything except negotiate.
Four to six weeks before the end of a tenancy, move the furniture and look. If there is damage, that is enough time to have the property treated, to have an invoice showing it was dealt with, and to discuss it before it becomes a deduction.
What You Are Actually Looking For
- Irregular thinning or grazed areas rather than clean holes
- Bare patches where the floor was covered by furniture
- Damage running along the carpet edge against the skirting
- Fine silky webbing, sometimes with grains of debris in it
- Small cream larvae, often inside a small case the colour of the carpet
- A fine sandy debris where something has been standing
Telling Active From Historic
This matters more in a tenancy than anywhere else, because it decides whether the damage happened on your watch.
- Active: live larvae, fresh webbing, loose debris, and damage that grows
- Probably historic: bare patches with none of those, and clean edges
- The test: mark the edge of the patch in pencil with the date and look again in four to six weeks
That pencil mark is the cheapest piece of evidence available to anyone in this situation, landlord or tenant.
If You Find It
Treatment starts from £220. Report it in writing, photograph it before anything is moved, and do not strip the room out — the webbing and debris are what tell us where to treat.
