How can I eliminate the smell of dead mice and rats? - in detail
Eliminating the odor that remains after a rodent has died requires a systematic approach: locate the source, remove the carcass, clean the affected area, and neutralize lingering scents.

Locate the body – Follow the strongest smell, check hidden spaces such as wall voids, attics, crawl spaces, and under appliances. Use a flashlight and a mirror to inspect tight areas.

Remove the carcass – Wear disposable gloves and a mask. Place the remains in a sealed plastic bag, then double‑bag and dispose of them according to local regulations. Disinfect the gloves before removal.

Clean the site – Scrub surfaces with a detergent solution (warm water and dish soap). Rinse and dry thoroughly. For porous materials (carpet, insulation), discard and replace if the odor persists.

Apply an odor‑neutralizing agent – Options include:

Enzymatic cleaners that break down organic residues.
Activated charcoal placed in the area for 24–48 hours.
Baking soda sprinkled on fabrics, left overnight, then vacuumed.
Commercial odor absorbers containing zeolite or silica gel.

Ventilate – Open windows and use fans to circulate fresh air for several hours. If the space is enclosed, run a dehumidifier to reduce moisture, which can amplify odors.

Seal gaps – After cleaning, seal entry points with steel wool, caulk, or metal mesh to prevent future infestations and related smells.

Monitor – Re‑sniff the area after 48 hours. If any trace remains, repeat the neutralizing step or consider professional pest‑remediation services that can treat hidden cavities with specialized foggers.

Following these steps removes the source, cleans the environment, and eliminates residual odor, ensuring the space returns to a neutral, odor‑free condition.
