Basically I have a carpet being eatencouraged by carpet moths and it is driving me mad. I have been hoovering madly, moving furniture and spraying stuff and they have got better but I have massive holes in the bedroom carpet which are very visible now that I've been moving furniture around. I think the floorboards are in reasonably good nick so was wondering if anyone had experience of hiring a sander to sand them. Was it hard? Was it worth the effort? Did you varnish or paint the floor after?
