Sometimes. A small animal in plain sight can be bagged with gloves and a heavy bag, sealed and disposed of properly. Hidden, large or long-dead animals are a different job, because fluids soak into materials and germs can spread.
The crew follows the odor, checks vents, attic access and crawl spaces, and looks for flies and stains. Sometimes a small camera or a small opening in drywall is needed. Once the animal is found, it is removed and the area is cleaned.
The smell comes from the carcass and any fluids, so the animal has to be found and removed. Air fresheners only cover it. After removal, the area is cleaned and treated, which usually clears the smell.
Rules for removing and disposing of dead animals vary by city and county, and animal services handle public property in many places. Worker safety follows OSHA rules for contaminated materials. Ask your city or county what applies where you are.
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.
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.
