Not true. Because they have a Caution label (least toxic category), most states do not require they be applied by a professional. Can be purchased on line at a number of websites by anyone.

They have EPA numbers on them so they would have to be applied by a licensed pest control operator according to most states. The amazon product does not so if someone had an RH issue behind a case that was causing silverfish I would control the RH with the non EPA listed Amazon product to control just the RH. Any museum worker can treat for RH problems in a collection environment. Joel Voron Colonial Williamsburg Foundation Conservation Dept.

I used food grade DE in my house when my cats had fleas. My reason for using DE, I have one cat who is very sensitive to flea chemicals and I don't like the chemicals in my house. I sprinkled the DE on my carpets, left overnight and vacuumed int he morning. You can even put a small amount on the cats as it will not harm them, except for the fact DE is a drying agent so it can dry out their skin and if you have too much on their fur and they clean themselves it could create some dehydration issues. You find on the internet some people mix DE and drink it claiming it has health properties--not my thing, but different stroked for different folks. Anyway, the DE did a good job of getting rid of my minor flea issue. DE is like talcum powder and the main concerns are not to inhale it, so wear a mask and lay it down carefully so not to create too many airborne particles. I have also used DE in my vegetable garden to get rid of slugs, but then it will kill any soft body insect-so the good ones too. Honestly, I never thought of using it in a museum, but in a low traffic area and caution used when putting it down, it should do the trick. I like the idea of using it in a museum storage space.

I have never purchased diatomaceous earth, or used it, but am considering the possibility of incorporating it into our IPM program.

I would also be interested to hear any opinions from people regarding the use of diatomaceous earth in museum environments for silverfish, and any other pest it has shown to be affective against. Do you just "sprinkle it in the cracks in the floor and/or along baseboard"? What would be the hypothetical concerns for using it on the floor in a storage space for prints and drawings? Any thoughts would be appreciated!Thanks,Todd-- You received this message because you are subscribed to the Google Groups "Museumpests" group.
