How Long Can a Carpet Moth Infestation Go Unnoticed in Maidenhead?

Why It Stays Contained

Left completely alone, this problem is remarkably static. The larvae do not travel far, they feed where they hatch, and the adults are poor fliers that avoid open lit space.

• A population under a wardrobe has food, darkness and stillness right there. Nothing pushes it to move
• The damage is under the wardrobe, so nobody sees it
• Adults emerge into a room, sit in a dark corner and die within weeks
• A handful of small moths a year is easy to dismiss and almost everybody does
• Nothing smells, bites, stains or makes a noise

Then Something Disturbs It

Building work does in a fortnight what the household did not do in five years: it moves everything.

1. Furniture out of every room at once
2. Carpets up, underlay exposed, gripper rods lifted
3. Skirting off, gaps opened
4. Loft cleared, stored textiles brought down
5. Rooms emptied and left standing warm and quiet
6. Everything carried between rooms, repeatedly

The population does not grow because of this. It becomes visible, and it becomes mobile — which are two different things and both look like an outbreak.

The Illusion, and Why It Costs Money

The natural conclusion is that the problem arrived with the work. It leads people to treat one room — the one that has just been disturbed — and to assume the rest of the house is clean because it has never shown anything.

It has never shown anything because nobody has moved anything in it. That is not evidence of absence, and a house mid-project is precisely the moment to find out properly.

How To Date It Roughly

• Faint thinning visible only in raking light — months at least
• An obvious bald area under one item — commonly a year or more
• Several separate patches in one room — more than one season
• Damage in more than one room — well over a year, because the adults had to get there and then breed
• Old grey webbing and empty cases — historic activity, whether or not there is live activity on top of it

None of it is precise. It is meant to correct the instinct that this started when the builders did.

What To Do With a House That Is Already Open

1. Look under everything that has been moved, in every room, not just the affected one
2. Look at the exposed underlay and perimeter wherever carpet is up
3. Look in the loft while it is cleared
4. Photograph what you find, with dates
5. Treat the whole property rather than the room that showed first
6. Do it before new carpet, new underlay or refixed skirting go in

Treatment starts from £220. A house mid-project is the most thorough access this problem ever allows, and it is worth using rather than waiting for the dust to settle.
