It is common for mice to die in human housing. Then a bad smell of a dead mouse spreads quickly. In this case, direct action is required to prevent worse harassment.
In a nutshell

- Neutralize the odor with a special agent from a specialist dealer

dead mouse
Mice often enter human housing in search of food and shelter. In addition, the rodents like to hide behind wooden panels, under the floor and in pieces of furniture. Entire families of mice often hide somewhere, for example in the garage, in the attic or in the basement. In most cases, the animal corpses cannot be found at first, but they can be recognized by their disgusting smell. Sometimes the house cat also brings a dead mouse home as a gift and just leaves it somewhere.

- Carcasses of dead mice decompose over time
- The duration depends heavily on the temperature
- penetrate concrete, screed, plaster and sandstone
- penetrate the joints of tiled floors
- are absorbed by carpets and textiles
- foul odor note contaminates the whole room
- especially settles on porous materials
Notice: The longer the deceased mouse acts on the ground, the worse the smell gets.
Quick help
Since bacteria decompose a deceased mouse, putrefaction gases are produced, which the human olfactory organ perceives as an extremely unpleasant odour. In this way, nature warns against poisonous and spoiled substances. Small molecules and chemical substances are still clearly perceived even in tiny doses. This characteristic olfactory note is sweetish and biting and hits the nose immediately. An instinctive revulsion follows, combined with disgust and nausea. That's why quick help is required to locate the object and reliably remove it.
- definitely try to locate dead mouse
- Carefully remove found carcasses
- do not touch with bare hands
- Wear rubber gloves
- It is best to put on a mask as a mouthguard
- then clean the surface down to the pores
- strong special cleaners are suitable for this
- alkaline slaughterhouse cleaners are ideal

neutralize odor
After the carcass has been removed and thoroughly cleaned, the smell of decay often still hangs in the air. If the escaping liquids have seeped too deep into the subsoil, in extreme cases the only solution is to dispose of them. Wooden floors in particular sometimes have to be removed and replaced in places. However, before these drastic dimensions, an attempt should first be made to neutralize the stench. There are special tools available in specialist shops for this purpose.
- Application of odor neutralizer to affected areas
- available as a spray or gel-like solvent
- Special agents are applied with a cold fogger
- sparingly mists affected rooms with fine droplets
- Droplet sizes adjustable between 5 to 50 µm
- It is best to let the device run for several days
- This is how neutralization of surfaces and ambient air takes place
- agents with surfactants and microbes are helpful
- direct contact with the odor molecules is important
- repeat the application in stubborn cases
- possibly even several times in succession
Tip: Since a cold fogger is quite expensive to buy, it is worth hiring a specialist to do it. Alternatively, the device can also be rented from shops that specialize in disinfection.
home remedies
There are many household remedies that help against bad smells in rooms. These are mostly substances that have a strong odor of their own. However, this only superficially covers the smell of decay. Once the masking effect wears off, the original stench quickly returns, and often even stronger. Therefore, in order to combat it successfully, the culprit must always be found and removed first. There are two methods to choose from when applying. Either apply the remedy to the affected areas or place a jar filled with it nearby. Ideally, leave the selected agent on for a longer period of time, but preferably over a period of a few days and repeat the application.

- Vinegar and lemon juice remove foul odors
- throw out used coffee grounds
- freshly ground coffee also binds odours
- Peppermint helps against bad odors
- repeatedly burn incense
- Sprinkle high doses of baking soda or salt
