You're one of the unlucky whose house or car has been infected with the dead mouse smell. It's a hideous stench that's pervasive nature you can never seem to escape no matter where you run. If the stench is in your home, I bet you're thinking of moving into a hotel and pray that the dead mouse smell leaves. If the mouse smell is in your car, you're probably thinking of driving your car into a river or off a cliff just to get rid of it. I can't say that I blame you, but there is hope.
It's bad enough you have to try to get rid of mice, now you have to deal with this?! Don't worry because the dead mice smell is not an impossible thing to get rid of, nor is a dead rat smell.
No doubt you have tried just about everything you can think of to get rid of the smell. How many scented candles have you burned? Probably have bags of potpourri sprinkled throughout your home too... I hate to say it, but this just isn't going to work. This will merely mask the smell of the dead mouse, and probably do a pretty poor job of it. This is a pungent smell that will pierce through any half hearted attempts to veil it. If you're looking to eliminate the odor permanently, there is a solution, so please continue reading on.
So how do you get rid of the dead mouse smell? First you have to get rid of the mouse that is causing the smell. Yes, I know - I'm master of the obvious. It's common sense, but it has to be said. For as long as the mouse is rotting or decaying, it will emit the foul odor that is invading your nostrils. Simple as that. That's only the first step though. Due to the pungent smell, it's likely that even after removing the decaying rodent, there will be remnants of the overpowering, musty smell in the air. For that you need to purchase an odor eliminator (not just a scent or perfume to mask the smell). If you eliminate the source, one application of the right product should do the trick permanently (or at least until you kill another mouse and it ends up rotting close to home).
If you can't find the dead mouse, you're going to have to wait it out. Once the mouse has dried out and fully decayed, the smell will diminish. Unfortunately this can take weeks or months. Luckily there is a product that can dissolve the odor, not just mask it. That's important, so I'm going to say it again. You do not want a cover up or perfume - you need an odor eliminator. The difference is that an odor eliminator will chemically bond with the smell and neutralize it in air, whereas a perfume only mixes with the rodent odor and attempts to mask it by overpowering it. That doesn't last. You need to neutralize it.
There are many odor eliminators out there, but the one that I recommend is Fresh Wave Continuous Release Odor Neutralizing Gel. This stuff gets out the worst of smells, no matter what the source. It is specifically designed to attack odors naturally and prevent the source's ability to produce the offensive smell in the first place. If you read the Amazon Reviews, the results of the product speak for itself. This stuff is also effective at getting rid of the smell of mouse urine.
It all boils down to this... find and remove the source of the dead mouse smell. Apply odor eliminator. If you can't find the source of the rodent odor, apply odor eliminator regularly until the mouse completely decomposes and no longer emits the smell.
