Hello,
today, while removing the wallpaper, we made a discovery: around some windows on the upper floor, there are black "spots." When you touch them with your finger, the black substance stays on the finger. At first, we thought they might be insects, but these things don’t move.
Can someone tell me what this might be?
A photo is attached.
Thanks,
Regards, Patrick

What is the best way to approach this?You’ll need to search online, for example, for mold lab testing. There are several companies in nearby larger cities that usually have websites explaining what kind of inspection is needed, such as room conditions, substrate, photos with a scale, etc. In the second photo, it looks like small ants 😉
