hi,cleaned carpets in a mansion of a house 6 months ago.Told the customer they have a problem with moths.Today they called asking for the whole house to be treated.Now what i remember of this house ,they have large cabinets full of books and furniture that would be a major problem to move and some with no way to get the repellent onto the carpet underneath.Of course these are the areas where the moths can cause most damage.I can ask the customer to empty all these units ,but would be a major upheaval.How would you approach it,thanks
