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.
Eventually it fades, but that can take weeks, and fluids that soaked into insulation, carpet or wood keep releasing odor. Removing the animal and treating the area is much faster than waiting.
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.
Sometimes, but not always. Many homeowners policies exclude damage from animals or pests, and wording differs. Call your insurer before work starts, take photos and keep receipts, and ask what paperwork it needs.
