Brilliant, thank you everybody! Yes, the first families I looked into were also the dermestidae, plus the anobiidae. I can also mention, looking at my specimens, that they are slightly more elongated and a bit less colourful than the Anthrenus species I usually encounter in Denmark, and more scaly/patterned than any of the anobiidae. The sign, though, that told me to look for a different family altogether, were the antennae. But then, my oldest book is only 30, so I didn’t get any further. ;-) Thank you, Tony and Armando, for digging deeper! In my pictures I didn’t succeed to get the antennae properly in focus, but when you google the suggested species Hylesinus fraxini or Leperisinus varius (those seem to be two names for the same species) one can see the spade-shaped tips quite nicely: e.g. https://www.kaefer-der-welt.de/hylesinus_fraxini.htm I’ll ask the people who live in the house to have a look at their firewood, but ash certainly is popular for this purpose around here.

However this doesn't match any of the dermestids that I know, and there are other families of beetles with scales, notably the weevils and bark beetles (Curculionidae). In this case the asymmetric scale pattern gave it away - most bark beetles are rather plain, but this genus has a couple of species with such a pattern. I used an old book that I've had for over 50 years to make the initial identification, and confirmed it with an internet search for images of the genus. (There's a limit to what I can keep in my head!) The other clue that I had was that Simon mentioned dozens of beetles trying to get out. In my experience that most often results from a mass emergence from firewood.

Tony, as an entomologist I trust your observation but wonder about the features that drew you to that diagnosis? I was looking at shape and scale pattern (though my amature eye).

They are usually associated with ash trees (Fraxinus), and tunnel under the bark. When they occur in large numbers indoors, the first thing to inspect is any firewood. It is most likely they are emerging from that. They do not present a threat to the building or its contents, except that dead individuals provide food for Anthrenus larvae.

The specimen is from southern Jutland in Denmark. Dozens of individuals of this species appeared inside an old, inhabited farm house (timber structures, probably organic filling material in ceilings, all kinds of possible food sources available, but the source has not yet been discovered) in the course of July, flying to the windows to get outside. They are about 3 mm in length. Colour isn’t great in the pictures, but greyish-brown with off-white scale markings is still pretty much what it looks like in real. Any help would be appreciated!
