The root of all evil is

. . . a cupboard at the top of the stairs containing an old rug, which has formed a sort of moth Waitrose, aisles and aisles of delicious things to eat. I now have to clean out the whole thing. The floor is covered with larvae.

On the plus side, they don't seem to have got into the wardrobe. I hope.

UPDATE
Having had the most disgusting morning putting half-eaten stuff and other stuff covered in larvae into bin bags, and having found a half-eaten vintage coat from the early 50s which a friend gave me in 1985, my cleaner has arrived and is going over the carpet inch by inch with a vacuum cleaner, crevice tool and insecticide. Next week the carpet cleaners are coming.

I have to go to the gym now and have my trainer make me pick up heavy things. Lovely. Then home to find out if this is the new mayor of London, as predicted by all the news media.

UPDATE UPDATE
After I spent four hours this morning clearing out the cupboard, spraying moth killer and laying down insecticide, and my cleaner spent five hours vacuuming, this evening the moths are still there, on the walls and ceiling in the hall.

I have had an email . . .

Greetings --

just a quick note of commiseration! it's a testament to the laxity of my cleaner that oh, god, nearly a year ago last november, i noticed some bald patches in a rug I'd bought at John Lewis (normally very reliable in all things) and when i turned it over, it was teeming with larvae and suchlike. it took me ages and ages to get rid of the damn things, using some of the same products I see you've got. unlike you, i'm not smart enough to store woolens in bags so ended up tossing a few things, though nothing quite as mind boggling as the rug itself! i'm not at all squeamish about bugs (rodents are another story) but I was grossed out. moths are so persistent, too.
and just when I thought it was safe, I saw one flying round the room the other night. Luckily, so far, seems to be a solo flight. But the shorter version is just to say perservere and I feel for you!
