Mice are highly social creatures. They live in a single nest, where they sleep, eat, and play together. They get lonely when they are left alone. When a mouse dies, they mourn their loss.
Mice also use their sense of smell to detect threats in another way. If they smell dead mice left in traps, they will avoid those areas, sensing that death may wait for them in those locations. That is why it is a good idea to remove mice caught in traps, so they are not allowed to decay.
Be aware that rigor mortis, the stiffening of the joints, typically begins within 10 minutes to three hours after death and can last as long as 72 hours.
When a mouse dies, its body starts to break down and release various gases. The result is an incredibly foul odor that can quickly fill a room. The odor of a dead mice might not be that bad at first, but it will continue to get worse until it overpowers your nostrils.
Clinical signs that signaled implementation of euthanasia included inability to walk, lack of response to manipulation, large or ulcerated tumors, seizures, and palpable hypothermia. In mice that died spontaneously, gradual weight loss was the most frequent and earliest sign of imminent death.

Mice are not afraid of new things or bothered by the smell of humans or dead mice on traps. If you have many mice, you might have to use a multi-catch mouse trap or a glue board.
Answer: The odor will last about 10 days or perhaps a bit longer. There is no certain way that the dead mouse can be found, and there are no chemicals that will take the odor away.
What does a dead mouse smell like? The smelly carcass is emitting a pungent odour of decay and a "bouquet" of toxic gases like foul-smelling of rotten cabbage thiols, methane, hydrogen sulphide, ammonia and pyruvic acid.
What Happens if Mice Die in Your Walls? If you have dead mice in your walls, they typically dry up in 10 days to 2 weeks. At that point, their odor dissipates. Without drilling holes in your walls, it's difficult to extricate the offending bodies and remove the source of the smell.
Spotting one elusive mouse typically means there are at least five or six hiding out in your walls, basement, or attic. This is particularly true if you see a mouse at night or in a low-traffic area of your home. For more proof of a full infestation, look for these indicators: Scratching noises in the evening.
Rodents such as rats and mice are associated with a number of health risks. In fact, rats and mice are known to spread more than 35 diseases. These diseases can be spread to humans directly through handling of live or dead rodents, contact with rodent feces, urine, or saliva, as well as rodent bites.
There is a way to tell approximately how many mice your home has welcomed. Check out the mouse droppings you see on your floor, counters, or furniture. If you find only 5 or 6 mouse droppings, that is a good sign, as that few droppings will tell you that there is only one of those rodents scouring about indoors.
These pests do have poor eyesight. They can't see colors and they cannot see very far away. However, mice have a very good sense of smell that makes up for their weak eyes. They use pheromones, or scent markers, to communicate with other mice and rely on scents to detect predators or other potential dangers.
If they're communicating to stay away from a trap because of the scent of human or dead mouse, things can get tricky. Mice have incredible memories. They can even remember who their family is and form bonds with them.
Much like us, if they do not have companionship, they can become lonely, anxious, depressed, and stressed. Mice and rats have complex systems of communication.
The odor of a dead mouse is a mix of sulfur dioxides, methane and other noxious gases that are produced as tissue begins to decompose. Unfortunately, this smell can be produced by any member of the rodent family (mice, rats, etc.) that may have found its way into your walls, attic or crawlspaces and died.
Create a 10/90 bleach/water mixture. Vinegar or commercial disinfectants are also good choices. After you've removed the mouse and cleaned the area, circulating the air will help the smell dissipate. You can do this by opening doors and windows, using a fan, or installing an air ventilation system.
A dead rat, mouse, or other animal smell can linger and produce an even stronger odor as time wears on until it's fully decomposed which could take 6 to 10 weeks.
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.
Rodents will feed on non-human foods like birdseed and dry pet food in a pinch. They have incredibly sensitive noses and can easily smell your food through walls and packaging.
Mice learn to avoid traps
Additionally, traps eventually stop working. As mice learn to avoid them. Mice are smarter than humans give them credit for. Only travelling in familiar places, with one side of their bodies against a wall.
House mice are not scared of humans and are sociable animals. This means they are far more likely to come into your home voluntarily. They live in both rural and urban landscapes, but may be particularly annoying for farm owners or those who live near open fields.
