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!

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

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.

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.)

Had an infestation of fungus gnats in my indoor plants. The handy spout allowed me to dust the dirt to help contgrol the eggs and hatchlings. I believe it worked pretty well, the infestation was under control in about a month. Fewer and fewer gnats were found in and around the soil.

Had an issue with cockroaches when a previous roommate did not properly store their pets' food away and basically left the bags of food open in the garage. Unfortunately, when we started to see cockroaches near the garage it was already too late. The house was infested, bombing it was a temporary fix, but the cockroaches always came back after a few months. Preparing the house for fumigation was time-consuming due to the number of people and pets living here, and hiring a professional exterminator is too expensive for us. We researched more natural ways to keep the infestation at bay and found diatomaceous earth. It's food-grade, so if this was accidentally ingested it would be ok. You do have to be very careful though, because this powder is so fine and if we breathe it in, it is very harmful to our lungs and respiratory tract. We masked up and dusted the powder very lightly on areas where we knew the cockroaches appeared and where not a lot of people or pets would access often or for long. We sprayed a light mist of water to keep the powder from flying up into the air just in case. It took some time for the powder to show its effectiveness as we still were seeing cockroaches, but by the end of the month, we all suddenly thought that there weren't a lot of cockroach sightings as in previous months. Additionally, it did help with the large ant hills near our front door. We originally bought this as it was small and affordable to try, definitely a fraction of the cost compared to fumigating or calling a professional. If it didn't work we would at least be able to use this in our garden and say it was worth a try. Since it works, we will be buying more diatomaceous earth. Edit: It has been over half a year since we got this. Realistically, I will say this did not eliminate all cockroaches, unfortunately. However, it has been effective for our infestation with some patience and time. We were using this product almost daily for almost 3 months until it got to the point where we were only seeing a sighting of a cockroach once a month. After that, we would put more focus on the area where the cockroach was seen and use this product there. I hated to live in the house due to how disgusted I was with it, but now it is very livable. For those in dire situations with no possibility for a more permanent solution, this is still a highly effective temporary solution.

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.

This definitely works to keep ants away. We get tons on ants that come through some cracks in the base boards, but they will not go near this stuff. The only issue is that you must cover every possible entry point or they will just come in another way. But as long as all opening are covered, this stuff is very effective.

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.
