I think the DE powder was probably sprinkled around, possibly an over 
application, and then the boxes sealed.  Do you see powder? It’s slow acting, 
but bed bug and egg dormancy period has passed well before the 10 year mark! 
Any bugs or eggs will have died. DE contains a small amount of crystalline 
silica compared to CimeXa dust where there is none – it’s all amorphous.

Hello everyone,
A curator is considering bringing in an archival collection consisting of paper 
and media materials that was treated for a bed bug infestation with 
diatomaceous earth 10+ years ago.  We don't have much information on how the 
treatment was implemented.  The problems with diatomaceous earth residue on 
collections materials aside, is it an effective means of treatment?  
Information on how long bed bugs and their eggs can remain dormant and how to 
best assess the efficacy of the remediation would also be greatly appreciated.
Many thanks,
Jessica

Hello Jessica,

I can’t answer most of your questions but diatomaceous earth is 
used for passive treatment of bed bugs and other insects. They physically have 
to crawl across the sediment for it to have effect, it scratches their 
undersides and ends up killing them. Exterminators will place it around trim, 
in corners, electrical outlets, anywhere that they may be hiding. Generally in 
treatment an insecticide or other poisonous substance is used as a more active 
treatment so you may want to research the types that were used at the time of 
treatment in your area for health and safety concern for staff. There is food 
grade diatomaceous earth so it isn’t in and of itself necessarily harmful to 
you beyond irritation to eyes or lungs even if this particular usage it isn’t 
food grade. The issue would be more if it’s ground into the collections or 
related concerns.

Typical ‘waiting them out’ treatment can be up to two years. If 
they’re been sealed or isolated for the 10+ years since treatment it’s likely 
that there isn’t a concern but I would be personally very concerned as you 
sound like you might be. No good story ever started with, “So I found this bed 
bug……”.

Jessica,


Diatomaceous Earth (DE) is not a particularly effective treatment for bed bugs. 
But, if bed bugs were actually present ten years ago, they would have long 
since perished. So there's no risk of contacting living bugs or eggs. The DE 
would pose only minimal risk. If you have a HEPA filtered vacuum, you could 
remove nearly all of it quite easily.

I've encountered this problem in an historic mansion in the Hudson Valley.  
Lots of adults indoors in pheromone traps, but no larvae or damage to the 
wall-to-wall woolen carpets.  Traced to pigeons droppings and nesting material 
on the roof of the adjacent veranda.

Hi Megan 
This is a Monopis species - almost certainly M. crocicapitella, the Pale-backed 
Clothes Moth (though it is known in the US as the "Bird Nest Moth"). It is 
becoming a frequent pest in domestic and public buildings in Europe, or at 
least it is coming to our notice more frequently, especially as it is attracted 
to Tineola pheromone traps. Although the adults can be abundant, finding larvae 
is proving much more difficult.
Best wishes
Tony

Hello Megan,

Certainly has a resemblance to a type of clothes moth. If it is, they 
tend to like a number of different textile type items but have a tendency 
towards animal hair/fur, clothing, carpets/rugs, and that type of material. 
Check your surrounding environment for similar materials and see if you have 
any larvae or more full grown moths. Depending on what you find depends on what 
you do. Anywhere from dry cleaning to large scale freezing. Keep the humidity 
under control, regular inspection, good house keeping policies, sealing of 
items (if appropriate), and closing up entry points will deter further issues. 
Sticky and pheromone traps are handy for keeping an eye on the situation.

It might be something else or could have come in on someone, lets hope!
