HARRIS Diatomaceous Earth Food Grade, 4lb with Powder Duster Included in The Bag

I use this daily. So glad to find it in this larger bag.

Messy

I got this product to sprinkle around my windows to keep ants out. Well, after digging through the bag of super fine powder to get the applicator out, I found dust everywhere...then I read the label, which says to avoid inhaling it and use a respirator and goggles during application. I was bummed because I have pets, and everyone says food grade DE is safe for use around people and pets - but its clearly not, for this type of application. Even closing the bag spouted dust...and the zip on the bag does not close. I poured some outside, but its so fine it just blew away and didnt go into the sidewalk cracks I intended it for. I couldnt even sweep it into place. Disappointed to say the least (for my intended application)! Im giving it 4 stars because if used as anti-caking for animal feed, maybe its awesome!! But not easy for novices to apply...

Me recomendaron este producto para las cucarachas y realmente ha funcionado. Hay que tener cuidado al usar la bomba porque expulsa mucho polvo, lo que te lleva a esparcir con brocha por las hendiduras para que no se acumule en exceso.

We had a major ant problem in and around our house and I sprayed this powder around the edges on the outside of the house and behind cabinets and along baseboards etc inside in order to help repel and kill the ants. We had such a large ghost ant population around here, that I had to use various efforts to discourage them from coming in the house. I used this and boric acid at the same time because I just wanted to make sure that something would work. I also sprayed all around the house and put ant stakes inside and outside. But I know this works, because there have been times that I used it with nothing else. The problem with all these anti-ant substances or methods is that what often happens is THE ANTS DIE IN TRANSIT. So I began to find dead ants here and there and everywhere. They often die before they get back to their nest, and in fact they die sometimes on their way into the house after crossing over the path of the boric acid or diatomaceous earth or poison. So Ive been finding dead ants here and there around my house for over a month now, and I keep hoping they will leave me alone, but they seem intent on wanting to live in and around my house even though I dont leave out food or anything. By the way I was told these are called ghost ants. They seem to be everywhere in the area of Central Florida I was living in. One warning is to be very careful not to breathe diatomaceous earth. It can actually cause damage to your lungs if you breathe too much of it. I see many people using it carelessly. Be careful! For example when you open the bag, the powder begins to sift into the air immediately which reaches your lungs, so I advise wearing a good mask such as an n95 when messing with this stuff. It is almost impossible to use it in any way without it getting into your air space. So you have to be careful. People seem to think because you can actually mix this with water and drink it if it is the right type, that it is not dangerous. No it is not dangerous to drink it in water, but it is dangerous to breathe it in its normal dry form. I also use this as a gnat killer by spraying it on top of the soil of my potted plants. This seems to be working well. Diatomaceous earth has many uses, so I recommend you read about it, but use it responsibly. I gave it only four stars, because the sprayer that they give you with it doesnt really work very well. At times it doesnt spray out at all and other times it sprays too much. It is very difficult to control the sprayer. Ive seen other sprayers of this type that work better.

I cant really say how well this works as either an anti-caking agent, or as natural pest control (the reason I bought it). But I stuck some under the microscope and its the real deal. Lots of diatom bits.

Our neighbors have a termite infestation somewhere in their yard and they have unfortunately climbed the outside of my room and burrowed holes in the window sill. Ive been using this on the inside and outside (on top of other treatments) and they havent come back since! The duster squeezer is also really helpful. Wear gloves with this!!

i poured this throughout all my floorboards to help with a roach problem i had, it did help alot but did not eliminate them 100%, also extremely messy.

I’m apparently really oblivious because when I bought this I didn’t realize it came with a nifty little tool to spritz the diatomaceous earth around with, but it works really well and the addition of it is much appreciated! I’m using this as a sort of barrier to keep potential (ear) mites from going into my bunny area while I treat them with Revolution so it’s gonna be hard to say if this specifically does anything to help but, I don’t doubt the efficacy.

So far so good!
