Unfortunately, the smell from a dead animal can take weeks and sometimes months to disappear. The problem with dead animals in a wall or somewhere in your house is that the dead tissue breaks down and the decaying tissue produces liquids that can seep into the wood in your walls and floor. Then the problem can be more difficult to remove as the smell can continue for a long time. Sometimes the odor is so strong that the wood sections of the house may need to be replaced altogether.

You can request a visit from a local pest control company for an estimate about removing the dead animal. If you wait, you may then need to replace the wood in the dead animal's location.
