Harris Diatomaceous Earth Food Grade, 5lb with Powder Duster Included in The Bag, OMRI Listed Approved for Organic Use

Great product, works as expected. We put this under our dog's bowls inside and outside to deter ants and other Critters. A small amount can be added to the dog's food also to facilitate in worming. This bag will go a very long way.

This stuff is a darned mess, but it worked. No fleas on the carpet or furniture. Do NOT use this directly on your cat or dog.

WARNING: graphic depictions of roach infestation. (But a happy ending!) "Diatomaceous earth powder is abrasive, and breaks down the waxy layer of the cockroach’s hard exoskeleton, killing it through dehydration. When they walk through diatomaceous earth, roaches carry away some of the DE that clings to the tiny hairs on their legs. They typically die later, back at their nest." I was skeptical. We had a really bad roach problem in our building. REALLY bad. They were in the apartments, the laundry room, the lobby, the hallways... The HOA is too cheap to provide any pest control, and just tells us tenants to pay for it out of pocket. I priced exterminators, and they were expensive- and with the magnitude of our infestation, would be REALLY expensive. It was time to DIY the roach battle. I have two cats, and like to avoid toxins as much as I can, so I wasn't about to set off insecticide bombs that leave a poisonous residue. I searched for an alternative answer to use to fight the infestation, and read that diatomaceous earth is effective at banishing roaches. This product, Harris Food Grade Diatomaceous Earth, got good reviews, and was really inexpensive, so I ordered a bag. Diatomaceous earth has the consistency and appearance of whole-wheat flour. It's not good to inhale it, so I wore a particle mask and put the cats in a different closed room when I treated the apartment with it. (But if the cats ran through it and licked their paws, it would not poison them.) The accordion-squeeze-thing-with-the-spout applicator bottle (included with the diatomaceous earth) made it easy (and actually fun) to distribute the earth. I squirted it everywhere- under all the sinks, along all the baseboards, under the bed, in the closets, behind the refrigerator and the stove- I applied it the way a priest would throw holy water around in a severely haunted house. (In hindsight, I probably used too much, because the problem was as bad as it was. You can apply just a dusting of it, and they will walk through it, and that will be enough. I re-apply just a very light amount about once a month.) And- sorry to be graphic- the roach problem was-- bad. As in they were crawling across the ceiling above your head in broad daylight bad. As in finding six of them drowned in the cat's water bowl in the morning bad. As in don't turn your back on your sandwich bad- or leave your coffee alone for too long bad. :/ This was even with us putting all the food away immediately, making sure the garbage can was always completely sealed, wiping all of the surfaces in the kitchen down constantly, getting the cat food bowls off of the floor immediately after they were done eating, and vacuuming constantly for crumbs. It didn't matter; they were positively everywhere. They had set up shop in this building (and especially, it seemed, in our apartment) and weren't going anywhere. I admit- the problem was so bad, I had my doubts that anything would clear it up. Maybe a constant bombardment of every surface by gamma or cosmic rays, something like that, might help. A substance that resembled flour didn't appear to be capable of an being effective weapon, let alone a lethal one. I did watch "what happens to roaches when they encounter diatomaceous earth" videos on YouTube, which were reassuring. But when they are crawling all over the place, you want something immediate. I did have a spray can of essential-oil based pet safe roach killer I attacked them constantly with, so that helped make it feel like something was killing them right away. I shouldn't have worried. After about three or four days- we started to notice that there weren't so many roaches around. (Again- this was after an infestation so bad it seemed like the roaches had rented the apartment- not us.) Every hour, and especially every day, there were fewer and fewer roaches, until it got to the point where we weren't seeing them at all. If you opened a cabinet, you might see one skitter away, or one would run across the kitchen floor. That was within the first three or four days after treatment. But they no longer "decorated" the walls and ceilings, or crawled across your feet as you sat working (yeah- it was that bad.) First only one in the morning, then none, and no more, was found drowned in the cat water bowl. Slowly but surely, the DT was working its silent magic. Every now and then I would apply a fresh squirt of DT using the handy-dandy squeezebox applicator- around the refrigerator and stove, along the baseboards in the kitchen. But I really didn't need to. Within a week, maybe nine days at most- they were ALL COMPLETELY GONE. Nada. Zilch. Oh-nay oches-ray. It was amazing! It all felt too suspiciously easy, and too good to be true, we thought. There must be some secret bivouac full of them somewhere, silently plotting their revenge, biding their time until they flooded the apartment triumphantly with their squadrons once more. But no- they were really and truly gone. (Oh, I know they are still around somewhere- probably every apartment building has some level of roach population. But the roaches in THIS building have come to learn that, unless they are wearing tiny hazmat suits, this is a completely hostile environment for them, and it WILL kill them. ) This bag of white flour-like stuff was one of the best investments we have ever made in terms of value for money. It would have cost a fortune to get an exterminator in here, for what would have needed to be multiple visits in a month, repeating for months. Instead- a sprinkle of (magic!) Harris' powder- and the vermin are no more. This product is, needless to say, HIGHLY recommended! By the way- it's been months since I treated the apartment with the earth, and the roaches are STILL gone. Also, the bag is still over half-full, and the amount I use once a month as a reinforcement sprinkle is negligible. Talk about economical! It's such a blessing to know this stuff works- that we have a reliable weapon in the roach wars- especially when it felt we were never going to be rid of those disgusting critters. We are, and remain, happily roach-free. :)

I picked up the Harris Diatomaceous Earth Food Grade mainly to help with an ant problem around my home. The bag is a generous size, and I like that it comes with the powder duster — that makes applying it a lot less messy and helps spread it evenly where I need it. While it did cut down on the ants outdoors, I still noticed some making their way into the house even after a few applications. It’s definitely useful as part of a larger pest control plan, but not a complete solution on its own. Overall, I think it’s a good value and I appreciate that it’s safe for organic use, but for stubborn infestations I’d recommend pairing it with other methods.

I inherited a house infested with fleas. We sprayed and bombed twice. For a while it was free of fleas, or so I thought. Recently, I sprinkled this all over the house. While it’s obviously very dusty, I appreciate the nontoxic quality. It’s been a few days, I haven’t seen fleas yet (not even spiders or roaches). Fingers crossed it holds up.

The stuff actually got rid of the flea infestation in my apartment. I needed to find a way to get rid of the fleas without moving my pets out of the apartment and I couldn’t find a way. Then I found this. And thank God this stuff actually works. You do need to use it for a couple weeks and reapply every 2 to 3 days and vacuum each time before you reapply, but it is completely worth it. So I got this and put it on all fabric surfaces that my pets touch in my apartment vacuumed everything else very thoroughly and gave the pets capstar and then gave my dog a chewable flea preventative as well, and the fleas are gone. The only thing that I will say is that you absolutely need to wear a mask while applying this and keep your pets away while you’re applying it because this stuff does go straight into your lungs I had a cloth covering my face the first few times and this stuff got into my lungs to the point that I spit up blood; because its made of tiny sharp little fragments that easily get into your lungs. But that only happened to me one time and from then on I wore a mask and it was fine. 100% worth it to get rid of the fleas and extremely effective.

Huge bag for the price. It even comes with an applicator for dusting the product around. This seems to be taking care of the fleas that my boys {dogs} have brought into the house. A light dusting on all the soft surfaces, let it sit for a few hours and then vacuum it up. Very easy to use with little smell. Just read the directions and try not to breath any in, a bandana around the face works well for this. I understand that it has many health benefits when ingested but I haven't tried that yet. Right now, it is only being used for flea control and some insect control on my vegetable plants. I would purchase this again.

We own our house and are very clean but have nasty neighbors and thus we have roaches. We used this with a fan in the kitchen so we get a nice even thin layer on every surface, that way the there so no where for the roaches to go but in the power and the its not poisonous to humans. If you make a dust cloud in the bag by spraying the dirt with the duster back into the bag, it makes a cloud of dust. Have an oscillating fan near by to evenly disperse the dust, and it will make it so that it looks like there isn't any dust spread but there is, its gets on other things but make sure to wipe them down. We live in a unit condo townhouse, with 5 other people attached to us...it took a few weeks but the roaches are gone. The ones I did see in the kitchen at night, i left them alone to walk in the dust, and then a couple days later, its been 5 days now without one in sight; and i check my kitchen religiously 1AM, 3AM when they are most active and think we are asleep or there is little activity. We also did other precautions like the following: - mosquito net all vents (bathroom vents, floor vents, side vents) - clean up all crumbs - sprayed dust behind dishwasher, under stove and under fridge and under the couch - seal up all holes that go into the wall like drain pipes; also dusted under cabinets - bought food seal containers - no dirty dishes over night - all garbage with food gets thrown out at night (ie. put into garage) no garbage with food in the kitchen over night We first sighted a roach around June 20th, and our last sighting was Aug15th. Between that time we saw around 50 of them, kill most on sight; my wife killed a nest they made in our juicer and so we threw out the juicer, and bagged our air fryer and toaster. I'm still waiting on a clear verdict before we go back to normal ie. waiting a month or 2 without seeing even 1, that way we know they are gone for good.

My favourite diatomaceous earth brand. In my opinion, it’s smoother and not gritty compare to some brands which I tried.

I am always looking for natural ways to rid my gardens whether they be floral or edible of pests without using chemicals. HARRIS Diatomaceous Earth does just that. It is food-grade meaning you can eat it if you wish. Diatomaceous Earth is a whitish, powdery mineral/clay that works as a mechanical pesticide and not a chemical one. It can also be used for many other things such as tooth or face polish, a source of silica when added to food, and cat litter deodorizer and it can be applied to pets to kill fleas. However, I use it in my garden. I sprinkle it on the soil both inside and outside. When a pest comes into contact with it, the clay absorbs the moisture from the pest and exterminates it. I bought the 5lb bag as I also use the powder duster to dust my 2 cherry trees. I got the idea from an organic apple orchard near my home. I have also eliminated all the gnats from my home plants using diatomaceous earth. There are only 2 disadvantages to the clay that I have experienced. One is that I need to reapply the clay after watering or rainfall but it is quick and simple. Two is that if it is a windy day and I am dusting my trees, I end up with clay in my hair and on my clothes. But no worries as it washes out and is good for your skin anyway.

I used this DE to kill and prevent thrips on my houseplants and any other pests that might come along. I put it on top of the soil of all my houseplants and tried my best to coat the entire plant (leaves and stems) on pretty much any plant that was infested or near any infested houseplants and we'll as sprinkled in around the door in the sunroom and on the tables and shelves my plants are on. I had already been using hydrogen peroxide in their water, yellow sticky traps, I sprinkled cinnamon everywhere (it kills them when ingested and they hate the smell) and I sprayed every 4 days with a Neem oil spray for a few weeks before I tried the DE so all I can say is I haven't seen any thrips in the week since I used this and there is no new damage to any of my plants for the first time in several weeks which makes me feel like the DE works really well. You do have to reapply the next day after watering or for outdoor plants after every rainfall as water makes it dissolve and if you try to put new DE on the soil right after watering it is still too wet on top. The bag is definitely very annoying to close but that's not a huge deal. One of the reasons I bought this product is that it came with a duster thingy that is supposed to distribute the DE evenly, it is so frustrating to use. It says to turn it upsidedown if you want more product and hold it right side up if you want to distribute less product. When you use it upsidedown it usually just sort of comes out all at once and leaves a clump of DE and if you turn it right side up either nothing comes out or just the tiniest bit comes out unless you were just using it upsidedown. So only every 5th-10th pump is actually the right amount of product, so you end up using way too much of it in the end. You also have to hold it sort of parallel to the floor for anything to come out at all so getting the underside of leaves is basically impossible with this thing. I assume that using the pump on plants is one of the uses but maybe I'm wrong, either way I just want to complain about how annoying it is lol.

Combined with baric acid sugar traps, this stuff seems to have gotten rid of my ants last year. While it doesn't kill right away, it does ward them off and make it difficult for them to get around.
