Saw this in passageway in the intersection of kitchen, living room and bathroom. There's no direct heating in passageway. I ventilate home regularly for 10 mins.

I also had seen this 3 weeks before and I had throughly cleaned it. Looks like this reappeared again. The 2nd pic is after I cleaned with Anti mould spray.

Any advise or recommendations on how to prevent it?

Much thanks 🙏

  1. It’s almost always a humidity problem.

    First thing I’d do is to buy a couple of electronic hygrometers. They are small plastic things; you can get them for <20€ a dozen on Amazon.

  2. Can you please upload a picture that is a little bit more blurry?

  4. Camera older than the house. Also what else should it be unless you shat at the wall 😅
