If it makes you feel any better Sue, the moths m in my house which of plagues us for almost a decade have completely gone as far as I can tell. I removed all carpets and underlay, I cleaned and then bleached all the floors and the gaps between them I hoovered between all the floorboards to catch any dust that was resting on the joints, every single nook and cranny in the house has been hoovered bleached and washed, every bit of moth-eaten clothing / carpet / rug / curtain removed and now we seem to be in the clear.
