Dear pestlist-members
Thank you all for helping me in identifying the beetles.
As you all tried to help me, I'd like to let you know what we find out.
Yesterday we looked more closely at the beetles
and the holes they are making in the wood - and
we've even seen one of the beetles just trying
to make a hole in the wood.
As far as we know now, it is a wood-boring
beetle and it must be a leperisinus varius.
Amongst them, it could be, that we have a few
Anthrenus (or something similar) - but they
don't seem to be the ones of which we have
thousands.
And we don't have the beetles inside the display
cases - except maybe one or two near a bird's
nest - so this could be one of the few Anthrenus.
But we have a lot more of the leperisinus varius.
Thank you again and best regards from Switzerland

Thanks for the photos. The way the head is
tucked at a right angle to the body, the clubbed
antennae, the mottled elytra, and the piles of
powder; I too agree these are not Anobium
punctatum, nor are they Dermestids. I have no
idea what they might be.

HI Tom,
I received the images attached to the original inquiry/post: maybe AOL did
something with the pictures.

Elisabeth -
Apparently some of the members of the pest list had photos of the
critters. I never received them. Birds nests often have Anthrenus in
them, feeding on the feathers. I'd get rid of them.
Some others have said you also have a wood-boring beetle. Would love to
see the photos.

Dear Thomas
Thank you very much for your fast answer!
As I received a quite similar answer, I checked again the exhibitionâ¤
and we also have 4 birdâ¤s nests. Iâ¤m just wondering how it comes that
there are so many beetles just because of probably two birdâ¤s nests???
Will the bugs be a risk for the objects in our next exhibition or can I
solve the problem in removing the nests?
And it also seems that I have two different problems (bugs and worms). But
> are the worms in the wood in this case less â¤Ïdangerous⤦ for the room
and the objects?
I called now a firm which is specialised in eliminating pest problemsâ¤
But Iâ¤m glad to have some help from museum-experts as well!!
Thank you again and best regards from Switzerland

If they are indeed Anthrenus verbasci, they are NOT coming from the wood.
They most likely are coming from the dead birds. Anthrenus larvae eat
protein, i.e. the dead bird feathers, skins, and entrails. The adult
beetles are attracted to light, hence they end up on the window sills and
in the light fixtures. Remove the dead birds.

Dear members of the pestlist
Iâ¤m the â¤Ïcurator⤦ of a little a Museum in Switzerland, but not
knowing much about pests. It would be great if you can help me concerning
a bug-problem.
At the moment, we show an exhibition about different â¤Ïphenomenas⤦ in
the near nature environment of the museum (Kuesnacht, Switzerland).
As the subject is â¤Ïnature⤦, our designers decided to use â¤Ïnature
materials⤦ and I agreed to do so. Now, I wouldnâ¤t do it anymoreâ¤
Because: we now have bugs in the exhibition-room. A biologist told me that
they must be Anthrenus, probably Anthrenus verbasci. The grubs/worms must
be in the wood we used and the bugs are lying near the window, most of
them dead.
As the removing of the wood would probably be the end of the exhibition
(it should actually not end before octoberâ¤), I would like to know the
risks and the problems and what else I could do instead of removing the
woodâ¤
Fortunately we donâ¤t have our collection/museum-objects in this room
except some « dead birds ». And it wouldnâ¤t be a problem, if the worms
will stay in the wood and eat this wood, in which theyâ¤ve come into the
museum.
Do the worms eat only the bark of the wood â¤" will it be a big problem
for the room itself (wooden ceilingâ¤), because now the bugs are lying
their eggs everywhere? And will they destroy the objects of our next
exhibition in this room? What are they eating actually?
What do I have to do concerning the room�
I send you a few pictures â¤" it would be great, if you could help me or
tell me who I could/should ask.
A big « thankyou » in advance and please excuse my Englishâ¤
Best regards
