Previous posts have all suggested good methods and treatments but you must move furniture !! The amount of moth damage that I find when cleaning carpets, is beyond comprehension, all should be moved & thoroughly vacuumed beneath. Make sure you have a Hepa filtered vacuum, as I have seen a lady spread them around the house, by using Henry and it simply blew them out the back
They will settle in dark places and items that never get moved are safest for them, although I use a biodegradable cleaning solution and that seems to remove moths & eggs, as easily as soil
