I am reading a book on Diatomaceous Earth by Tui Rose called "Going Green Using Diatomaceous Earth How to Tips." She says that straight food grade DE is not sharp like glass, it actually works to kill pests through dessication, or dehydration. Industrial grade DE is heated and the heating process makes it sharper, like glass. If you are using food grade DE it is not glass and not the sharp edges that are killing the pests.
Food Grade Vs Industrial Grade
I have been reading all of the suggestions and am planning to try some. I don't have a question or remedy to offer, but felt I must let you know about a dangerous option.
I've used Diatomacious Earth for years, I even used it to get rid of a horrific flea infestation in my asthmatic boyfriends house with no bad effects. It works against all insects and parasites. The IMPORTANT thing to note is that POOL GRADE D.E. IS EXTREMELY DANGEROUS AND CAN CAUSE SILICOSIS (scarring of the lungs similar to asbestos poisoning) The only safe D.E. to use is natural pulvarized or ground D.E. that can be found in plant nurseries and food storage shops. This D.E. has NOT been superheated, a process which creates fine threads of silocone glass which makes it a better filtering product, but makes it dangerous to handle or breath. Flour grade D.E. is meant to be used in graineries as a bug and egg deterrant is fine enough to mix with flour. The Regular D.E. can be spread on carpets, or the cracks between wooden floors. Plan on not vacuuming for a while(like a week) in order to allow the D.E. to cut up and dry up the little buggers, and be prepared for a little dust to be produced for a short while as you walk on it. I've even heard of it being used a a coat powder and mixed in feed (for horses, cats,and dogs) but I've never tried that personally. I sprinked it in the carpets and brushed it in with the broom and let it sit for couple of weeks, them vacuumed and reapplied. This with Advantage treatment took care of all the fleas and there were none for the rest of the year.
Well I'm off to try an ear mite treatment on my new cat. Thanks for all the suggestions!
