I think this stuff is really working!! Saw a dead cockroach laying a few inches from where I sprinkled this stuff. And the ant infestation by our front door is gone!

Works well for all our bug issues. Earwigs, spiders, crawly creepy things are all no longer as annoying in the droves we were battling. Did a great job of helping with our OMG bed bug situation as well. And there is so much! Nice to have a large supply on hand for future use instead of one little bottle you have to replace rapidly.

You get a lot for the price. Seems to work well. I'll likely order another

Recd fast but I don't see how it kills quickly I still have spiders fleas and ants

and it is a fine, fine powder

This product poses some questions. I have sprinkled it only around the trash area once when i saw enough ants to make it worth it and it was interesting to watch all the ants starts to shake and then when I checked later they weren't there. However, since I only treated one area, it wasn't a surprise that there were still ants appearing periodically.

Problem is this thing called silicosis. As a ceramic artist, I know enough to make sure I am not breathing in silica dust, and there is silica in this product, and it is a fine, fine powder.

Then there is the question about food grade v. this stuff which is pesticide. There is a difference between crystalline and amorphous DE, with the crystalline being the kind that is most harmful on inhalation.

I am suspect about whether it is a good idea to be dusting this stuff all over the house, under furniture and have heard that the effects of it are eliminated if it is wet. Being that it isn't good for inhalation, I would hesitate to use it on the exterior of animals, but it is my understanding that ingestion doesn't pose as much a problem, if any.

There is info from the CDC about amorphous DE and silicosis online at the American Lung Association, and Amazon won't permit me to provide links to informational sites because it might be spam or something.

Because it is so fine, I wonder if covering the nose and mouth with a wet towel and using gloves and long sleeves would be enough to make it safe to sprinkle in places where a dog's nose wouldn't investigate. Another question is eliminating it once the need is no longer there.

Bottom line is that I believe this is an awesome pesticide alternative, but cover the respiratory with a wet cloth to diminish problems of inhalation and use some gloves and maybe do some homework and use reliable sources.
