Full Answer

The smell of a dead rat lingers until decomposition is complete, which can take more than 3 weeks.

Step 1: Eliminate the carcass

If possible, find the dead rat to eliminate the source of the smell. Look for flies, maggots, or damp spots on the wall or ceiling. It is extremely expensive to tear up a house in search of a dead rat, so other remedies might become necessary.

Step 2: Purify the air

Air cleaners sometimes help lessen the smell of a dead rat. They filter the air to remove particles that cause offensive odors. Although they cannot completely eliminate the odor, they can lessen the impact on residents of the house.

Step 3: Neutralize or mask the odor

Odor neutralizers employ bacteria to break down odor-causing compounds in the air, while odor masking agents release a pleasant smell to cover up the smell of the dead rat. Neutralizers are more effective, but masking agents are easier to find and use.
