Our museum is enclosed by a pond, so moisture problems are not unknown to us. We will start checking for any microclimates and deviations in the air-conditioned areas. I have attached two further insects where you might come at aid for us. I am not sure if this moth is a risk for our silk wall covering and curtains. The fly I have no clue to what this might be. Your help is appreciated.

They are miniscule, they look like booklice but I am not shure. On the 4th photograph shows a beetle, but I cant figure out if this one is a treath to our collection our building or not.
