The wings may be from ants and not termites?
Are the wings being discovered in a readily observed space or could they be
from an old infestation and just being uncovered now?
If near a window the wings are probably fresh.
I can't imagine termites having enough meat on them for carpet beetles to take
hold. I was under the impression that they would desiccate rather quickly.
What type of fumigant has been used and for what type of termite?
If your cases with the carpet beetle problems are built ins and sealed you need
to see if someone can get a kick plate off or find a place where you can drill
and send a borascope in to have a look under them.
There is a possibility that there is enough old dust hair and skin under there
cases or the floor for that matter where the carpet beetles have set up shop.
May be two completely separate issues going on as a coincidence.JTV

Hi Adrienne
You are right that the insect bodies are left in treated items, and they can be
a food source/attractant for dermestids.
The wings may be alate wings. Reproductive termites have two pairs of wings
that they shed following colonising flights.
Do you know what sort of termites were in the building? What treatment was
carried out?
Best wishes

Hi All
I have questions about carpet beetle. I know they are very damaging to
collection they can destroy a textile collect in a few days if there is an
infestation. They can go unnoticed for long time because of their sizes. Here
is the issue about six month ago our main exhibit hall had termites. Which has
been an ongoing battle for over year now. I am not 100% sure because of how
many times fumigated has happened before I started here. I know that they have
fumigated at least three times since 2017. The last time being about six months
ago. Which the workers in the exhibit hall thought that there were no more
termites. I thank the Manger said that his staff began to fine wings about
two-three months ago, and what they thought was termites. The pest guy kept
telling him that they were nothing that no way there could still be termites
and that pest that they were fining would not harm the items on display.
I was asked by my Manger to go take a look at what they were fining to see if
it was more termites. However, it was not termites it was larvae of an
Dermistidae (Carpet beetle). In addition to this they are still finding
termite wings. Which makes me think that they may still have termites. I had
saw an email from pest list when someone had asked if dead pest attracts
dermestid beetles, the answer was no but they do not help. The termites were
of course in the walls and under display areas that were made of wood, and
other areas. These areas they were unable to remove any dead termites, so any
termites that were dead that were in the walls, under displays that were unable
to move were left. An exhibit hall worker found three alive dermestid beetle
larvae this morning and this afternoon they found five adult beetles all dead.
Here are my questions:
1. Could the beetles be feeding on the dead termites and causing the
wings to be present?
2. Is it possible that the termites are still there and that the
fumigation did not work and the beetles are still feeding on some of the dead
termites?
3. If the dermestid beetles are in the wall feeding on something how are
we going to eliminate them? The area where the beetles are being found at the
display does not move it is attached to the wall and it is wood with textiles
display on top. It only has a piece of lather and feather that can be removed
and CO2 or frozen. I real do not see what they could be fed on. Other than
something behind the display and wall. However, there are other areas in the
exhibit hall that are textiles that are at risk, large animal skins, cases of
feather, leather clothes, and fur.
4. Has anyone fumigate and been successful in killing them? If you do
fumigate does it leave dead bodies in walls which could cause an another
infestation.
I have found dermestid in other areas on our campus. In the Archives building
the area was much smaller and easier to clean. We were able to freeze and CO2
everything.
Any suggestions would be help.
Thanks,
