How to Prevent a Dead Animal Smell
When dead animal smell decomposes outdoors, their odor dissipates as they break down into the soil and grass. However, when an animal dies inside a home, the odor can be overpowering. Odor-eliminating cleaners and odor-neutralizers can be purchased at most home improvement stores. Follow product label precautions and directions carefully to avoid overdoing it, which could lead to the odor being trapped in the air.
When a rodent dies in your attic, crawl space or wall cavities, it will begin to rot and decompose. Eventually, maggots will be formed from the rotting tissue and the stench will get worse. This can take a week for a small animal like a mouse or rat, and over a month for larger animals such as raccoons and opossums.
Nose Knows: Dealing with the Lingering Odor of a Dead Animal
If you smell a dead animal odor, it is important to find the carcass and discard it immediately. This will help prevent a bacterial infection from occurring. It is also important to clean the area where the animal was found thoroughly and to wash any clothing or bedding that came into contact with it.
The best way to prevent a dead animal smell is to keep wildlife away from your home. Check the roof and outside of your house regularly for open entry points, such as missing soffits, and trim bushes around your home. This will discourage animals from gaining access to your property and entering through openings in the attic or walls.
