Harris Food Grade Diatomaceous Earth is an exceptional product for anyone looking to enhance their home’s pest control and improve overall health. As a natural and non-toxic solution, it’s perfect for use around pets and children, providing peace of mind while tackling common pests.

The fine powder is easy to use—simply sprinkle it in affected areas or mix it into animal feed for added benefits. I’ve noticed a significant reduction in pests, and it also serves as a great supplement for improving digestive health in pets.

The packaging is user-friendly, allowing for precise application, and the quality of the diatomaceous earth is top-notch. I appreciate that it’s food grade, ensuring safety for all household members.

Overall, Harris Food Grade Diatomaceous Earth is a versatile and effective solution for pest control and health benefits. I highly recommend it for anyone seeking a natural alternative!

5.0 out of 5 stars Wonderful stuff
Reviewed in the United States on September 26, 2024
This dust is very messy, but very effective! I have used it to stop garden pests, to keep vermin out of my cabins & sheds, to stop ant trails into my house, to dust cats & dogs to get rid of flea infestations, to dust environments to kill fleas, and even fed it to pets to kill intestinal parasites. It is wonderful stuff. It works by mechanically scraping the waxy coating off an insect. This makes it lose water rapidly, dehydrate and die. It's a mechanical effect so they cannot really ever develop a resistance to it, and the effect happens slowly, so the insects never learn to associate the powder with illness. They just crawl through it, and to them, it is like crawling through broken glass. If they scrape or clean it off themselves, they're only speeding up the effect. The only problem is handling it - it's messy, although it doesn't stain, is chemically inert, and is easy to wipe or wash off with water. The bag is sealed, but the internal zip-lock seal is not, so when you tear that opening, do it slowly or use scissors, and have the bag inside another, plastic bag to contain any puffs of powder that come out.

I recommend a powder duster tool to use this, but you can also cut the corner of a zip-lock bag and use that to dispense the powder. A small spoon will also do the trick. Dust around the door jambs, behind fridges & stoves, and wherever else moisture or bugs are likely to congregate.

The powder contains silica (diatom shells are made of it), but as I recall, this is not a reactive form of silica, so you cannot get silicosis from it. It is not dangerous like other silicates are, but it can cause mild respiratory irritation if you use it a lot. You can wear a mask when you dust it, or just do what I do and pull your shirt collar up to cover your nose. For normal use around the house, you probably won't need to do any of this. I just mention it for those who will be using this heavily and often.

EDIT: I'd like to add some information. I did a LOT of research about whether food grade diatomaceous earth is dangerous. It is not! It is USDA approved as generally safe for people and pets. It's the amorphous and crystalline silica that's dangerous, and those are found in insecticide DE and filter medium DE, not food grade DE. Food grade DE is purified. You can use it with no worries. I cannot add links to a review, but you can try searching "food grade diatomaceous earth safe" or similar, to find a number of science papers.

5.0 out of 5 stars NO MORE ANTS
Reviewed in the United States on November 29, 2024
i used this to lightly dust the baseboards of our kitchen and it immediately solved our very bad ant problem, super impressive, nontoxic, it's been 4 months and no sign of ants, we've swept and mopped plenty of times in that time and haven't reapplied it
if this is what u need it for it's perfect! probably don't need this much though

4.0 out of 5 stars Great for houseplant pests
Reviewed in the United States on July 10, 2024
I bought this to use on my houseplants to manage pests and found it very useful. The amount you get for the price is great and it’s easy to use. The zipper seal doesn’t work on mine so I need to clip it closed and store it in a dark, dry place to avoid any moisture.

Reviewed in the United States on November 4, 2024
I had a TON of wolf spiders in and around my house. I put this outside my house by my doors, and inside my basement by the garage door. Since I have sprinkled this around I have not seen a single wolf spider. Not sure if it is killing them or just deterring them, but they are no longer in my house! I also covered my outdoor plants in this before bringing them inside and have seen zero bugs on those! You do have to reapply after rain but most spots are protected under my roof a bit.

5.0 out of 5 stars Leca not so good
Reviewed in the United States on September 30, 2024
Diatomaceous earth is a must in my home with so many plants. It’s a good value for what you receive and very dense .What I do is use a strainer to dust everything evenly. I also use it indoors and outside. If I see pests outside this does the trick . If I see them inside a trick , I learned to rid them for good is by sprinkling on top of soil. So many other good uses for this product.

5.0 out of 5 stars Fungus gnat problem completely solved with this stuff!
Reviewed in the United States on September 20, 2024
We had a serious fungus gnat problem in our house because of all of our house plants. I'm serious, I was killing like 30 of these things a day. I put this in every plant that is in our house or enters our house new and we have basically eradicated the fungus gnat problem in the house. This stuff is AMAZING!
One note, make sure you do this outside as it can be dangerous to breathe in the dust :)
