And cedar wood. You can sometimes buy small pieces of it that you can sand down to expose a fresh surface when they stop working, so they last for years and years.

There are hundreds if not thousands of species of moths in the UK, and only 6 of them eat clothes and carpets. We saw an elephant hawk moth recently. Link to ukmoths.org.uk  here. (P has a moth trap, which attracts them overnight and in the morning you spend hours identifying them and release them.)

I have scarlet tiger moths in my garden. They are really lovely, and the caterpillars are attractive. The caterpillars eat comfrey leaves, and then move on to other things, fortunately reaching strawberry leaves only after the berries have finished. I am happy to sacrifice a first cutting of comfrey to them, though this year there were far fewer than usual so they didn't do much damage.  See the ukmoths site, or here for even better pictures I found.
