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 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.

Kind of pricey considering you can buy 25 lbs for like $20, but works great for any bugs, including ants. I'm sure the high price is for the bottle. It works well for application in normal households areas.

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 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.

Worked Fantastic on flea situation!! Love the pointed spout made application easy. ❤️

This was a reasonably priced version of this product. I have used similar products before with good results. The fact that it is a non toxic way to get rid of roaches or other insects is ideal. I needed to apply some in our master bathroom, specifically in some cracking tile grout where I noticed some baby roaches were hiding (ewwwwwwwwww) and didn't want to use toxic substances in there. I had manually killed a few babies over the course of a few weeks prior that I horrifyingly witnessed venturing out of that crack. I really DID NOT WANT them to grow into adults as I have an unnatural fear of roaches since childhood. I have no idea how many babies are in one roach egg... and I don't want to know. I found this product very difficult to apply, but it is probably just the nature of powders. I wore a mask so I wouldn't breathe it in because even though it is not toxic, any powders going into your lungs is a bad idea. I found that I either couldn't be sure it was coming out at all OR I had an excessive amount pour out. Perhaps a better solution is to pour a bit into a small cup/plate and use a small paint brush or an old, spare make up brush to apply. I ended up dumping large amounts out, wasting quite a bit of product, and smearing it into the places needed with my hands (less than ideal). I tried to get it in all the cracked areas and then went around the bathroom floor boards and behind the toilet for good measure. I also put some in the corners of my Master bedroom and along 2 sets of sliders in two rooms, where there are definitely some entry points. The heavy rains in the summer drive insects to seek dry shelter in our home we notice. Although we do get monthly outdoor pest control service on the exterior of the home, it isn't always enough. It is hard for me to know for sure if this product has worked because I haven't found any dead insects, but I also have not seen any live ones since-- a positive in my book. The babies may have died behind the tile, and while not ideal, is better than them being alive and growing into big nasty roaches. I prefer to pretend they walked in the powder and went outside in the yard to die. I know we do still need to seal up the shower cracks, but it will take a lot of time and money to do it right. Curse the previous owners who used thick sandy grout lines! I will be coming up with an ad hoc solution in the meantime. If you have never tried a product like this before, I recommend giving it a shot. I will update my review if I see roaches rolling around in this powder and laughing at me in defiance. Until then, I am assuming it is working as intended.

Very effective and easy to use. The applicator tip makes it simple to apply in cracks, corners, and other tight areas without creating a mess. I also like that it’s food grade and chemical-free, which gives extra peace of mind when using around pets and the home. The powder is fine and consistent, and the container seals well for storage. Works great for multiple uses around the house and garden, and a little goes a long way making it an excellent value. Overall, a reliable product from a trusted brand.

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.
