HARRIS 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!

This is a great product for eliminating internal and external annoying critters with exoskeletons. I’ve been able to eradicate moth infestations, as well as infestations on plants. It’s tasteless and safe, as long as you do’t breathe it in. It’s a great addition for gut health of animals, as well as humans. A very little daily amount is helpful, added to whatever natural regimen already underway. Inexpensive, I’ve been adding it to my oatmeal for years. It’s tasteless, odorless, and mixes easily in a sprayer you’ll need to shake before using. If it works for animals, why not humans? This is food grade.

Easy application puffer tip for the win! It makes it so much simpler to get the thinnest layer possible so the bugs go through it, and not around it. I love this product. Easy to use. Highly effective. No potent odor, but I don't put my nose up to it. Sealed tight. Lasts a long time, but I reapply periodically after a deep home cleaning. This container value for the money is an A+ in my book. I buy their resealable large bag and use a small scoop and funnel to refill the bottle.

this is a good product and it works well for killing bugs without poison, but it’s really hard to use the puffing dispenser tip without getting earth all over yourself so wear a very good N95 mask when you use it

The best non-toxic roach and ant killer! It works on anything with hard exo-skeleton, suffocating them. So if you have hermit crabs, or an open fish tank, remove from the area before use, and until the dust clears. Also, once wet, it is no longer effective.

I used this on my grape vines because some bug was eating perfect circles into each leaf. By the time I used this diatomaceous earth powder the vines were almost bare. Within a day visible new bug bites were nonexistent. Within a couple of weeks the grape vine is full of leaves and hardy. It works fast and effectively. I like that’s its food safe too.

I hope it works in killing the fleas. The problem that I had is that it didn’t puff; so, I had to dispense it by hand. This resulted in way too much product. After much brushing in, I was able to get most of the product into the throw rugs. The rest was all over the floor. After vacuuming up the floor, I lightly vacuumed the throw rugs which still contained a lot of the dust. Bottom line is that squeezing the bottle did not dust the carpet.

Works well and easy to use. Good price and fast service.

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.

I don't like spraying chemicals around. I like that this is non toxic. Two applications, two weeks apart, which took about 5 minutes each, and my silverfish problem is completely gone.

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.
