You think the EPA, the University of Oregon, and the National Pesticide Information Center are wrong?

Seems likely. Rather, they stated that 'fact' without anything more than anecdotal evidence. This paper investigates a far more likely method of action: http://zero.sci-hub.tw/673/f8d7a6469e96789d8c958eb3c4efdc46/cochran1995.pdf http://zero.sci-hub.tw/673/f8d7a6469e96789d8c958eb3c4efdc46/...

  You're flat wrong. I didn't bother checking the other claims that logfromblammo made before my previous comments, I accepted them at face value, but I did this time; Boric acid has a hardness of 3 not 1 as he claimed. Diatomaceous Earth has a hardness of 1-1.5. [0][1] I looked at the source for the wikipedia claim that logfromblammo described so: "which does not contain anything remotely close to the text added". The source does support the claim in wikipedia. [2] >Pesticide products containing boric acid and its sodium salts are registered in the U.S. for use as insecticides, fungicides and herbicides. As insecticides, some act as stomach poisons in ants, cockroaches, silverfishand termites, while others abrade the exoskeletons of insects. The foundational premise behind his original post "unsourced wikipedia edit mislead other websites" is flat wrong. And on top of that, his reasoning for why boric acid wouldn't be a good abrasive "mohs hardness of 1" is also wrong, and egregiously so when the infamous Diatomaceous Earth that he claims is being mistaken for boric acid has a mohs hardness of 1-1.5! It's an irrelevant argument. My initial diagnosis of logfromblammo being the one who was confused was absolutely correct. Very disappointed in both of you. Hopefully many people weren't mislead by being convinced by logfromblammo as you were.

I think they are referring to pesticides that contain boron, and not specifically to the individual chemical component B(OH)3 (s), a.k.a. solid boric acid. I can easily imagine a commercial pesticide targeted at ants and roaches that contains borates, sugar, and diatomaceous earth, because that is exactly what I use in my own kitchen, made from the individual components. It is effective, and has low toxicity to humans and pets. But to be clear, it is abrasive because the D.E. component is abrasive, not from the boric acid. D.E. is actually the only powdered pesticidal substance I am aware of that kills via mechanical means.
