HARRIS Diatomaceous Earth Food Grade, Half Pound with Easy Application Puffer Tip

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-toxic2) Very effective against ants and cockroaches3) Can be used both indoors and outdoors - be careful if indoorsCons:1) Requires reapplication for best results if it rains or gets windy2) Careful when applying if windy - DANGEROUS to inhale or get in eyes, otherwise non-toxicOverall, it’s an affordable, effective, and safe pest control option that I’ll continue to keep on hand. Highly recommend.

I was getting mystery bites at night and couldn’t figure out why. Talked it over with my best friend Chad (okay, technically ChatGPT), and he pointed me toward diatomaceous earth. Between a deep clean and sprinkling this around my bed and furniture, the bites stopped. Huge relief.You don’t actually need much at a time, so this half bag is basically a lifetime supply. Shipping was fast, the product is clean and easy to handle, and I’ve had zero issues since using it.The applicator is 100% worth the extra spend — it makes placing the powder exactly where you want it way less messy. Without it, you’d be tempted to just dump and hope for the best.Bottom line: does what it says, lasts forever, and has me sleeping bite-free.

I used this on my cats and it appears to work. I found lots of suspicious instructions on the web, so I just used my head. I dribbled maybe 1/2 teaspoon of the powder on the back of my kitty's necks, and gently massaged it into their fur. I only used a little as this was a test. I observed them over the course of 2 days. I saw no unusual coughing or scratching, or other behaviours, no vomiting. They seemed quite normal and happy. At 2 days I checked them both with a flea comb and found no fleas. Normally I would get 5 or 10 off each cat. I am going to continue checking them and do the same treatment IF I start seeing fleas again. To me this makes sense. The DE should eventually kill any flea that comes in contact with it. The fleas must go through the neck area in order to get to the cats mouth and eyes for a water supply. A little DE around the neck will force them into it. There is no real need to dust the cats entire body. I'm not even going to treat their bedding at this point as what I'm did has been very effective. Make sure you get the FOOD GRADE. I got the wrong DE that was not food grade and my cats hated it I tried putting it in their beds and they stopped using the beds immediately. That's when I saw my mistake, I had purchased the wrong product. The food grade appears to have no odor to them. I tried a little on another of their beds and they didn't notice. -- I used Cheristin for a couple of years but it no longer works on my cats. the fleas in my area have developed resistance to most pesticides at this point. Since DE physically cuts holes in their exo-skeleton, experts say the cannot develop immunity. I hope not because this stuff is really working, and completely nontoxic (except to crawling insects!!).

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 stuff is really good. It will kill pretty much any insect that comes into contact with it. The downside is you do need to use some caution when using it. It is a fine dust of what is basically glass shards. In small exposure it is fairly innocuous to people, cats, and dogs, but in larger exposure such as breathing it, or getting in your eyes it can be really bad news. To insects, however, it is like being forced to crawl naked through broken glass. It gets into the soft joints of their exoskeleton, cuts them, and absorbs their blood.I recommend wearing a mask and full-wrap safety goggles when applying it. To remove it, do not sweep it. Instead, wipe the treated areas with a wet cloth, or mop. Rinse and repeat as needed. Rinse cloth or mop thoroughly to remove residue.
