You can use natural odor neutralizers, such as vinegar and baking soda to absorb foul smells. Vinegar is a natural disinfectant and can help absorb odors instead of masking them.
Vinegar: Fill multiple cups full of vinegar and place in the area of the source of the odor. Ground coffee: Place ground coffee filter packs or ground coffee in the area of the bad smell. Baking soda: Mix baking soda in a spray bottle of water. Spray the source of the bad odor several times daily until it dissipates.

The smell of a dead rat can be harmful to a person's health due to the toxic gases and microscopic compounds of the dead animal that are constantly being released into the indoor air. Since most homes are not consistently ventilated, the gases permeate into the respiratory tract and can potentially cause illness.
Try using white vinegar

The smell of rat urine can last for several days or weeks depending on the humidity levels in your home and how much time has passed since the rat urinated on your floor or wall. The longer it sits, the stronger it will smell, so it is important to clean up any rat urine as soon as possible.
A dead mouse should not be left to rot inside your wall, because its corpse could soon attract fleas. With an electronic borescope, you can locate the corpse's whereabouts by drilling a coin-sized hole, a few inches off the ground, into the drywall of the cavity that seems to be emitting the smell.
Cover your gloved hand with a plastic trash bag, pick up the remains, then invert the trash bag over the remains and seal the bag. For larger animals, use a shovel to place remains inside a plastic trash bag, then rinse off the shovel with water.
Mouse and rat carcasses release a potent odor that can penetrate through air ducts, walls and floors. The stench is so strong that it can cause headaches, nausea, and vomiting. As it turns out, there are two main culprits: decomposition and bacteria.
Baking Soda

Dead animals are a threat to public health because of intolerable odors and the potential spread of diseases such as Salmonellosis, Campylobacter, Clostridium perfringens, and other zoonotic diseases.
As dead animals decompose, bacteria that may normally be contained within the animal's body can be released, exposing people to potential disease-causing pathogens. Disposal of domestic animals and pets that have died are the responsibility of their owner.
On average, a rat takes roughly 2-3 weeks to decompose; however, lower temperatures will increase this time period significantly. Once the body has decomposed, the smell won't instantly leave your home. Instead, the foul smell will still be lingering in your home roughly two weeks later.
The most likely clue, especially in summer, will come in the form of flies. You will see an influx of flies, and you might even be able to track them to the source if the animal died in your walls.
