Remember the last time I did the repair of your family elders. If a very long time, and you can't even remember when, and get rid of the smell is to glue Wallpaper, paint the Windows and floors. Usually after that the smell stops bothering.
But one room repair is clearly not enough. Dilute some bleach in water and wash all cabinets, nightstands and wardrobes on all sides. Things also need to wash again, because they've had time to absorb all unpleasant odors. Dry linen in the street, at the same time, it also will erode.
Guide the treatment of all carpeting in the house. Preferably wash them outside with a powder or give the flooring dry. If this is not possible, by any means). Dissolve it in water, apply the foam on the carpet and carefully RUB. Allow the product to dry and vacuum it on both sides.
Don't forget to spend "audit" all of the kitchen cabinets, throw out all the junk and spoiled food. Pour grits in new bags and tie. Cabinets be sure to treat with a solution of bleach and only then play everything in its place.
