After a while the odor due to dead things goes away, as I know from experience.

Replacing the carpeting is a good idea. You might want to replace any upholstery, if there is any, as well. This includes mattresses.

Baking soda also does great things, both sprinkled around by itself or in solution.

Really do a good job on flushing holding tanks, including any for potable water. The last should probably be thoroughly flushed, then have a solution of chlorine bleach (Clorox) sit in it for for a couple of days, and then again thoroughly flushed with clean water.

Check the oven and the stove, too, if you haven't already.
