Tonya, The National Pesticide Information Center (funded by EPA) has a factsheet on diatomaceous earth. The portion that talks about silicosis is at https://npic.orst.edu/factsheets/degen.html#study. Note the comments about crystalline vs amorphous diatomaceous earth. You can scroll up and down from there to read the rest of the factsheet. (I believe they are reworking their site, so it looks a bit odd.)

This thought always puts me off these types of solutions.

Having a licensed pest control operator puff amorphous silica gel dust (.03 microns or brand CimeXa) with a bellow behind non movable furniture and into structural voids where dust accumulates and/or critters hide would be more helpful. ASGD is much cleaner and far more superior at scarifying insects waxy cuticles compared to DE.

Do not click links, open attachments or take action unless you know the contents are safe] Hello, pesty people, I have a question: are there any concerns with using an occasional light dusting of diatomaceous earth along the edges of the walls and in the entryway of our museum, which is carpeted, to assist with the management of dermestid beetles, such as black carpet beetles and varied carpet beetles? I appreciate your comments. It seems like a good, non-toxic tool, and I've used it the past couple of months with some potentially optimistic results. Thank you, Rachel Minor Rachel Minor Museum Supervisor/ Curator SRJC Multicultural Museum 1501 Mendocino Ave. Santa Rosa, CA 95401 707-524-1862 https://museum.santarosa.edu/<https://museum.santarosa.edu/><https://museum.santarosa.edu/%3Chttps://museum.santarosa.edu/%3E> I acknowledge that we gather at Santa Rosa Junior College on the territorial traditional land of the Pomo People in Santa Rosa and the Coast Miwok People in Petaluma, past and present, and honor with gratitude the land itself and the people who have stewarded it throughout the generations. -- You received this message because you are subscribed to the Google Groups "MuseumPests" group.
