To think that we can’t put up with the smell of dead mice for weeks on end?

2 weeks ago, I thought there was something wrong with the drains as it smelt like something had died. We called out Thames Water and all the drains in the road were clear and then our next door neighbours (terraced house) said they had discovered they had a mouse problem and they had called out pest control and the mice had died under the floorboards.

The house and everything in it absolutely stinks and on top of that, we now have a house absolutely full of massive, fat, juicy flies that are clearly feasting on the dead bodies.

I’ve bought some neutradol. And left out bowls of bicarbonate of soda but short of burning the entire house down is there anything else we can do? The house smells disgusting!

The smell doesn't last as long as you think it will! Plug in essential oil diffusers, open windows everywhere you can, small bowls of fresh ground coffee dotted about (this is odd but it works well) and lush bath bombs lying around the house helped us

These are great, we had dead rats under floorboards and we got a few of these (although I also had to move out for a couple of weeks to an Airbnb for the worst of it). Long story. When the flies came later we got one of those electric fly swatters (quite satisfying!) and covers for food. Very stressful though I really sympathise.

Booooooooom · 01/05/2026 19:26

Thanks, I am exploring all these options!

It takes about 3 weeks for them to fully decompose on average then the smell leaves. It is vile. I’m still traumatised from a rat infestation.

You need Oust spray, brilliant stuff for exactly this issue.

might try that tomorrow with all the windows open - rather annoyingly it’s in the hallway so not a lot of through air if you know what I mean

Coffee grounds really helps

Disagree that mice don’t smell when dead. I was sitting in the lounge with my son and husband this week and my son and I could smell something off.
It was a dead mouse behind the sofa courtesy of our cat .

It really stank!

The problem is, if it's mice, they breed so quickly and then you're overrun and they start coming into living areas like even your bed. I know this from awful bitter experience

It’s been about two years. I think it’s a squirrel. They come seasonally have babies and leave. Bit concerning for the electrics. But so far it’s been ok 😬

Notmyreality · 01/05/2026 21:58

We had this. Unless you are prepared to tear your house apart you just have to wait it out I’m afraid. Took about 3 weeks for the smell to stop.

Dalmationday · 01/05/2026 22:03

no advice other than to go on holiday for a week or two leaving some strategic windows open

Awful smell in the bedroom once found a dead mouse under the bed. Thanks cat!! Even when I got rid of the body cleaned the carpet there was a whiff for a couple of weeks.

HiCandles · 01/05/2026 22:35

Timely thread for me. We have been ignoring the mouse living under the freezer hoping one of us would catch it, which we do average twice a week thanks to darling cats. Well no luck this time. The unmistakable sickly sweet smell of dead mouse warming through in the freezer machinery filled the air and I have spent my Friday evening cleaning his stash of mouldy stolen cat biscuits, excrement (turns out mice are tidy, all the poo was in one area oh so conveniently practically impossible to get to and full of nooks and crannies), and his little solid warm body drying against the hot thing under the freezer.
I'd be ripping up floorboards too, OP! The amount of mouse poo and wee will shock you.
