You are not gonna like this....no amount of spray of ANYKIND will get rid of the odor. all it will do is ake it into a flowery, or fruity scented decomposing body. call an exterminator to see if he can find it, otherwise you will need to wait it out at some motel until the mouse has compleatly decomposed to nothing but bare bones...and even then it may still linger. BTW this could take a while, so pack heavy.
FEBREZE is different from other flowery things. It form a molecular "bubble" around the smelly molecule, walling it off. I've always been leary of Febreze - its presence will kill a bird in 2 seconds! The bubble molecule is too large for the bird's lungs. I wouldn't routinely use it around people with Asthma. You know, however, it might just work for handling the smell of decomposing mouse!
A raw onion (with cut surfaces) may act as a sponge for the smelly molecules. Can't hurt.
it may be under the house or in the walls i would suggest calling someone professional about it, I had a friend who couldn't where "that smell" was coming from turned out a coon got up in the crawl space and died and maggots started pouring out of it.
it is very toxic and can kill
Mice are known to be sensitive to the smell of a dead conspecific, which can deter them from coming out or approaching the area. The scent signals danger and a potential risk to their safety, so they may avoid the area to minimize any threat to themselves.
A dead mouse can start to smell within a day or two of its death. The smell can linger for about a week or more, depending on the conditions such as temperature and ventilation. Proper removal and cleaning are essential to get rid of the smell effectively.

Have you not seen the huge public health advertising campaign? There are billboards and television adverts everywhere that say: "The surgeon General warns that smelling the dead mouse smell may be hazardous to your health".

They make the house smell like dead rodents!!
A smell will not harm you. But the rotting bodies will carry germs and parasites.
There could be a dead person or dead animal in the house, or spoiling meat as from a refrigerator or freezer. Vultures are attracted by the smell of carrion and many species have an exceptional sense of smell.

If a mouse is dead and you are trying to locate it, you can use your sense of smell to detect the odor coming from it. Look in hidden or hard-to-reach areas where the mouse may have died, such as behind walls, under furniture, or in crawl spaces. You may also consider using a black light to search for any bodily fluids or stains left by the mouse.
