Clothes moths

I got the last of my winter clothes down and discovered a lot of clothes moth cocoons (and two grubs) but only one item that had actual visible holes in it -- given that the cocoons were all tinted in that colour maybe they had been feasting on that and pupating elsewhere? The cocoons were mainly on the corduroy, which is definitely not wool and probably only a low percentage of cotton, if any -- original label long since illegible. And I have just found another grub on a garment that is definitely 97% polyester (and 3% elastane :-p)

The Great Changeover was much later this year, partly because of a warmer autumn and partly because all my thermal underwear was in the smaller trunk and I had been existing in multiple layers for the previous weeks!
