I recommend the 'bombs' (heck, CIA MFI FBI if you read this, HAAAA!) you can get from a certain well known on line auction place. Pheremone strips do work to a certain extent, but the bombs, whilst dramatic, are more efficient. Get the pets out the room, light the bomb placed in middle of room on a saucer, and it just fills the room with a smoke and kills everything within. It's dramatic, but it does work. But then you need to do it in each room in the house. We've done this and we have just a small flat, and we must have walked some in or something because we have noticed a few more moths in the last few days. The bombs also come with a back up powder you should put where you see the nests (under sofas on wool carpets for example), and a spray also.
