I have just discovered that a number of my woollen jumpers have moth holes in them. I believe mothballs are no longer available. Does anyone have any idea about what I could use to rid my closet of the pests? Thank you

I've put a few drops of lavender oil on cotton wool make-up pads, which I then put into small zip-lock plastic bags, leaving them unclosed. I put them at the back of shelves in closets, and haven't had trouble with moths since. The same trick seems to work with silverfish - I put some at the back of bookshelves. Eventually you need to renew the oil if you're still having problems, but it is worth trying, and it doesn't involve nasty chemicals!

That's a great idea, Karena. Years ago I bought lavender sachets from my supermarket. You could hang them between coats etc. Haven't seen them for ages.
