Where do you buy diatom dust xr?

you could try twenga, they seem to have alot of great deals on at the minute and have a wide stock of produce so you should give it a go?

-- previous poster, perhaps an employee of twenga? Diatom Dust XR is merely a trade name. I just bought some from Tallman Scientific, is bulk freshwater diatomaceous earth repackaged in a ziploc bag and taped up with clear tape and a home-printed label. But I presume it is actual diatomaceous earth, which is also available, in similar repackaged form, in many places on the Internet, though not, apparently, anywhere in New York City retail stores. They make it sound so flashy, and if you get it from them the "bed bug barrier tape" is simply double-sided duck tape. I tried putting diatom dust xr on top of it, which they don't talk about, but we'll see how I fare. I think, touch wood, that I'm winning the battle so far.

Good luck

What are diatom shell uses?

Diatom shells, also known as frustules, have various uses due to their unique properties. They are commonly used in water filtration, as their porous structure can effectively remove impurities and toxins. Additionally, diatom shells are used in abrasive scrubbing products, such as toothpaste and metal polishes, due to their gentle but effective exfoliating properties. In agriculture, they can also be used as a natural insecticide by disrupting the exoskeletons of insects.
