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 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.

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.)

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.

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.

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.

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.
