Thanks everybody. If we do use diatomaceous earth it will be food grade and the EPA says it's not hazardous to humans or animals unless exposed directly for an extended period of time. The stuff they use in swimming pools is the extremely hazardous stuff. Even though it will kill the pest slowly we want them killed. Sticky traps can only do so much. We've been researching ways to do more without using conventional chemicals. Thanks again for everyone's input!Dave, we do have an IPM system. In fact, I wrote it. Researching non-chemical alternatives when there is evidence of infestation is a part of it.

www.cityofangelsconservation.weebly.comSenior Conservator & Museum ConsultantDavid HarveyI would never use diatomaceous earth inside any building where people working or visiting or where collections are stored. The fine dust can be hazardous. You need to get an IPM (Integrated Pest Management Program) in place. That includes monitoring, identifying and closing points of entry, reducing food sources for pests, and using "green" methods of pest control. Any infested collections should be bagged and isolated from the rest of the collection/museum. Sometimes freezing will eliminate pests, sometimes anoxic treatment - it depends on the pest and their life-cycle. Inspect ALL arriving objects, art, books, crates, for pests when they arrive. Inspect the outside of your building and consider moving/removing landscape against the building- eliminate sources of water from basements etc.You need a strategy.

Buffalo, WyomingJim Gatchell Memorial MuseumJessica KnightHello Listservers!At my museum we have recently discovered an entry point for pests which explains the influx of roly polys, spiders, crickets, and SILVERFISH. We are in the process of getting the problem fixed, but in the mean time we need to do something about the infestation in this area. Has anyone used diatomaceous earth in their collections area? From what I can gather online there is no risk to people or objects, just the little critters. Any advice would be helpful.
