Diatomaceous Earth Food Grade, Half Pound with Easy Application Puffer Tip

This HARRIS Diatomaceous Earth is a fantastic natural solution for pest control. Since it's food grade, I feel much safer using it around the house and near pets compared to harsh chemical sprays. The standout feature is definitely the "puffer tip" on the bottle—it makes it incredibly easy to apply a fine, even dust into tight cracks, baseboards, and hard-to-reach corners without making a huge mess. It’s an efficient, non-toxic essential for any home maintenance kit!

It works. It kills bugs and dries them up. It is mixible. I mix it with a concoction of powders. It is even more effective and faster active. It is safe to use around pets in certain amounts. Will not use around pets one can mix it with Borax, boric acid, clove powder, and pet carpet insecticide. These ingredients work well with the diatomaceous dirt. There was no leakage but getting the cover off was hard. I wouldn't use this product to ingest although some people ingest diatomaceous dirt to strengthen their bones. I wouldn't do that. To me it is simply for killing insects.

Diatomaceous earth is utterly natural, safe around any pets, but bad for insects — their little bodies get micro-scratches from it and they desiccate. Pets and people, will just think it’s a fine powder like baking soda or something. I’ve used it for example in the entrance to a hornet’s nest between bricks in my house’s exterior, so that every exiting hornet gets hit by it. It is truly food safe, so can use it in kitchen if you need to. Diatoms are ancient one-celled critters, long dead and gone but their shells remain. Pretty good value. Definitely effective for killing little bugs in a safe manner.

A little bit goes a long way. So for me this size is great. My vegetable plants start off great but eventually the heat causes them stress and the insect problem begins. A little powdering of this does the trick and it's food grade so no worry of toxic insecticide. There are feral cats in my yard and I use this lightly in areas where they sleep to help with fleas. I used it frequently when I had chickens. Always food grade for animal safety. When applying, it's the fine dust that does best and sometimes this is hard to achieve. If you put too much the insects will just avoid walking through it. It must be reapplied after rain or weather. This size is not likely the best bang for your buck if you need large areas treated for insects. The nozzle is not ideal for dusting but then I haven't found any that work with diatomaceous earth. It often comes out in a stream. A household sifter is probably the most effective for just a fine dust. Remember to mask or be cautious. Even though it doesn't smell the little particles can irritate your lungs and your pets lungs. The pets licking after you dust them lightly is a very good reason for food grade. (There are reports of feeding this, always food grade, in measured amounts to your flock or pets to control internal parasites. I definitely have no experience with this but it is worth exploring.)

This stuff really works! HARRIS Diatomaceous Earth is super easy to use—so easy, in fact, that my 3-year-old climbed up on some boxes, opened it herself, and started sprinkling it on the ground like it was chalk art in a bottle (thankfully not on herself!). That just goes to show how user-friendly and mess-free it is. I applied it near our basement entrance, where we were seeing several ants a day creeping inside. After using it regularly—about once a week, the number dropped dramatically. From finding 10+ ants a day to just a couple a day in 2 weeks, and then eventually none at all after about a month. It made a huge difference. I also used it while in Hawaii, where the cockroach situation can be intense. The cockroach population definitely went down after use in the condo, and one morning I found several large dead cockroaches suddenly in a pot of water—something that had been sitting out for weeks with no activity before. Clearly, they were drying out and desperately searching for moisture. Pros: 1) Easy to apply and non-toxic 2) Very effective against ants and cockroaches 3) Can be used both indoors and outdoors - be careful if indoors Cons: 1) Requires reapplication for best results if it rains or gets windy 2) Careful when applying if windy - DANGEROUS to inhale or get in eyes, otherwise non-toxic Overall, it’s an affordable, effective, and safe pest control option that I’ll continue to keep on hand. Highly recommend.

Effective physical insect control. Has dramatically decreased the number of insects in indoor areas where I used it to line entrypoints. Apparently it's non-toxic, so I definitely prefer it over insecticides. But it's more a preventative/supplemental measure than a solution. For something like ant infestations, I'd suggest you use it in conjunction with ant bait (don't pour this around the bait though, you want those ants to live). It comes out like baking powder. I just poured a little in the desired areas then spread it using a small brush. The included spout isn't convenient for larger areas, so I'd suggest something like a bulb duster instead for that. You're apparently only supposed to apply a very thin layer to flat surfaces, because if you can clearly see it then the insects can definitely see it and will avoid it. Not that effective outdoors as rain will wash it away.

Arrived broken

a tremendous all natural pest control powder, very happy with it.

Took long time to arrive (uk) was “delayed at customs “ for several days.

Got rid of the fly larva in my house plant soil. Thank you!
