Damp (?) smell in kitchen.....

[BaconAndAvocado]

No idea what it is!
Ive cleared and out and cleaned all the kitchen cupboards, which is the rough area it’s coming from, but it’s still there.

Wonder if it’s anything to do with all the rain we’ve had over the past week.

Could the smell be coming from behind the oven?

Is there anything I could put inside the cupboards to neutralise the smell?

Much rather find the source but that’s proving futile!

I bet it's a potato under the kickboards

We’ve looked behind the kick boards but maybe not that thoroughly...

Omg... This is me! Everything cleared out of offending cupboard and surrounding, oven out and thoroughly cleaned and disinfected. Still remained. Almost an ammonia smell. Called out pest control as convinced myself must be a rotting carcass or critter bodily fluid. No sign of mice. I am at a loss.
I put a scent burner (the ones with a wick that you blow out) in that cupboard to treat the smell
Am suffering with sinusitis atm so my sense of smell isnt great but family tell me the smell is much less.
We have discovered a flat roof leak, we can't see how it connects to the 'smell', but just wondering if you have a leak anywhere?

We had this. Cleaned everything, pulled out fridge and cooker etc. Eventually found the cause, one of my plants was rotten and stank! Was on high shelf but I was convinced the smell was something that had spilled on floor. Hope you find the cause. We took weeks to figure it out!!

The smell eventually just disappeared.
Have a feeling it was related to the torrential rain we'd been having, as after the drains were cleared it, thankfully, went away.
