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

To post to this list send it as an email to [email protected]<mailto:[email protected]> To unsubscribe look at the footer of this email. ----------------------------------------------------------- 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.
