The smell of dead mice can last up to two weeks if not treated properly. However, if you do not get rid of them quickly enough, the odour will spread through your home or business premises, making it almost impossible for anyone to stay there unless they have a strong sense of smell or are used to such smells.
Chances are that the carcass will dehydrate in a few weeks at which point the microbes that produce the smell as they decompose flesh will perish and the smell will vanish. In the meantime an air freshener can mask the smell. If the stench is truly overpowering, an ozone generator can be rented and run overnight.
Mix equal parts water and white vinegar in a spray bottle. Use this solution to spray and wipe down the affected spot. The vinegar will help eliminate the pungent smell and disinfect the area, making it fresher.
If you have a chemical sensitivity to amines, then breathing in the fumes from decomposing rodents can be a health issue because that foul smell comes from amines like putrescine and cadaverine.
Locate the source. As soon as you notice what you think is the dead rat smell, start looking for an increased presence of flies, maggots, beetles and other insects that are attracted to dead animals.
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.
Try deodorizing with baking soda, charcoal, or pet odor enzymatic sprays.
Vinegar is a great and cheap option for cleaning the home that is safe but also effective at neutralizing strong odors.
The truth is that if there is a chance to experience a mouse bite, while you are snoozing, it's a minimal one. The critters are scared of humans and the only genuine reason to find one in your bed is if there's any food source for them, like crumbs, for example.
Use a mild detergent mixed with water to wipe down the surfaces. For fabric areas like carpets or seats, consider using an enzyme-based cleaner specifically designed to break down organic matter and neutralize odors. Be sure to follow the manufacturer's instructions for safe and effective usage.
For a natural solution, you can try the following: 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.
If you choose to wait it out, it can take up to 3 weeks to a month for the stinking odour to pass. After this time, the carcass has had enough time to completely dry out, and the rotting process has passed through its most noticeable phase.
As many know, dead mice give off their own smell. Strangely enough this smell can attract other mice, especially when food is scarce. That's right- mice will eat dead mice if they need to. They are scavengers which means they will eat whatever they can possibly find, including their fallen cohorts.
When they feel threatened, mice play dead until all danger has passed.
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.

Once you've gotten a handle on your unwanted visitors, clean the droppings. Wear a mask and gloves, and use a 10 percent diluted bleach spray, or something such as Lysol, to spray down the surface well.
Unfortunately it may take three weeks or more to completely decompose. A professional may be contacted to break through and rebuild affected walls. This can be costly and not a viable option. Even after elimination of the source of dead rodent smell, the unsettling scent may linger for up to two weeks.
Dry coffee grounds: Coffee grounds absorb odors well and emit a pleasant coffee aroma. Place grounds in small bowls near the smelly area to do its magic. Air purifiers: This is a more costly solution compared to the others, but can be pretty effective at eliminating odors and removing pollutants from your home's air.
It is usually difficult to remove them when they are inside a wall. A room deodorizer might help. The only way to get rid of the carcass would have to be by cutting into the wall. This may be difficult, as the odor may permeate through the walls and it is hard to localize the exact point to cut the wall.
Thoroughly wet any contaminated areas — including trapped or dead rodents, droppings, and nests — with a 10% bleach solution. Here's how to do it: Mix 1½ cups of household bleach in 1 gallon of cold water (or 1 part bleach to 9 parts water). Make this solution fresh before each use.
Will this remove the smell of a dead mouse? POOPH works on organic materials. It will not get rid of odors created by in-organic materials (not from living matter) like artificial chemicals.
