Help! I’ve a horrible smell in the house

[Boohood]

We have a smell coming from a room in our house. It’s a small unused kitchenette, off a bedroom (weird house). The kitchenette is tiled. Would the smell of a dead mouse or rat come through the tiles? The bedroom has wooden floor. Maybe it’s a dead mouse or rat there? We have had this smell for many months. It seems to come from the kitchenette but hard to be really sure. We have just got a man in to dismantle the kitchenette in order to get rid of the smell. Help me please!🙏

No chance you have a cat and it’s cat pee? Other than that yea unfortunately could be a dead mouse!

thank you. We have a cat but he never goes in there. He’s toilet trained. It smells more like something dead

A dead mouse shouldn't smell for months. It would dry out and become dessicated. I speak from experience!

This is like the start of a Netflix documentary

lift a floor board - could be burst drains under the house

So has it been dismantled? And there’s still a smell?

You said it seems to come from the kitchenette, why do you not know for sure? Is it more intense in there? Is there a window, could it be from outside? Can you smell it in the bedroom, is it just as strong?

I'd try boiling water and bleach down the sink first. Unused plugholes can dry out and if the ubend isn't sealed by water you can get the drains smell coming up through the sink.

Anything electrical in there? When we had an unexplained, bad smell it was a short circuit near the electric meter and fuse box. It was a chemical smell in our case but some describe it as a fishy/ammonia or dead animal smell.

Could the smell be coming from the light fitting? Some older light fitting can burn and small like dead mouse.

How long have you had the kitchenette? Could be an uncapped pipe if you’ve done any renovations. Or just water sitting in the pipes, if the taps are rarely used?

I've had a dead rat under floorboards in the past. It was horrendous and led to me eventually taking up a floorboard. The farm down the road had knocked a shed down and set the rats off looking for a new home. They also put bait down to kill them which led to the corpses. There were 3 😢🤢

Put bleach down the plug hole and especially down the overflow hole. Fixed my smell problem which was gunk stuck in the u bend under the sink.

Thanks everyone. We found an uncapped pipe so it could be that @Puppyyikes . We’re going to pull up the floorboards tomorrow. Suddenly I’m finding it difficult to smell it. Having been obsessed with this smell for 6 months. I’m feeling a little deranged

I'm leaning towards @SqueakyDinosaur's suggestion. We get a horrible drain smell in our bathroom when the bath hasn't been used for a while (cos we mostly have showers) and the water goes out of the u-bend, allowing the smell to come up from the drains. Just running some water into the bath usually fixes it immediately by filling up the bend again, only thing is we have to remember to do it every so often or it happens again. So if there's a sink in there that hadn't been used for a long time that could well be the cause.

We’ve just had this problem in a bathroom - has a bath that never gets used and it started to reek. Have run the bath tap for ages to fill up the U bend and all fine now.

The sink drain has dried out?
