  1. It is super interesting that this chemical can be used for so many different things as you mentioned. I like that it is a non-toxic agent that will take care of most of the garden pests out there. It’s a bummer that it will kill the beneficial insects in the same way. But I guess that’s just the tradeoff you have to deal with.

    • This product will work wonders, the thing however is that you can use DE carefully around garden plants keeping it away from the flowers, or just cover your garden plants with burlap when treated. Hope this helps.

  2. We grow our own vegetables and use organic methods, so I am always looking out for ways to control pests and insects, while still be natural and not affecting the safety of eating the food. So this is great to come across diatomaceous earth, which will get rid of pests, without affecting the veggies. 

    Do you know where I can buy diatomaceous earth? Will I find it on Amazon, or in my local garden centre? Thanks for advising.

  3. I’m so glad to have found this article. Ants have always been a problem for my small backyard garden. And I always wonder why the worst hit is my chilli plant. Ants run up and down the plant stems especially when the plants are flowering. With your recommendation, I hope it works. Thank you, Norman.
