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
Yes.
A week or thereabouts. Once it dries out completely, the smell will be gone.

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".
Perhaps a dead mouse.
Until it dries out & no moisture is left in the carcass.
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.
