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

a tremendous all natural pest control powder, very happy with it.

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.

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.

This works. I have a Hibiscus tree that I put outside during the warm months and some gnats got in the soil. I applied the DE over a course of three days, my soil was too wet. I saw fewer and fewer gnats. After 6-7 days the gnats were gone. Be patient it doesn’t work instantly. I ended up with a thin layer of DE on the top and I just mixed it in the soil one I stoped seeing the gnats.

Good product. Not much to say about it, it is what it says..
