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. Louis N. Sorkin, B.C.E.

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……”.

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. Richard J.
