The smell can last a few days to a few weeks, depending on the size of the animal, the weather and where it died. It fades faster once the animal and soaked materials are removed and the area is treated.

No. Wildlife and pest professionals deal with live animals and seal entry points. You get a cleanup team for carcasses, fluids, nests and odor, and the two services often work together on the same job.
As an animal decomposes, bacteria break down tissue and release gases with a strong, sickly-sweet smell. In an enclosed wall or attic, that odor has nowhere to go and spreads through the house. Removing the source is the only real fix.
A dead animal can carry germs, so protection comes first.
