can this product be used to kill ground bees
Answer by ChewySep 17, 2020
Harris chose to market their Freshwater Food Grade Diatomaceous Earth as a feed additive for animals. Unfortunately for legal reasons they cannot recommend using it for anything other than what is printed on their label. This Diatomaceous Earth is not sold as an insecticide.

Can this product be dusted on my herb plants to kill bugs? If so, will the herbs then be safe for human consumption if I wash them before consumption?
Answer by ChewyAug 03, 2021
Harris Food Grade Diatomaceous Earth is not labeled with instructions to use on plants to kill insects. They cannot advise use other than as the label directs.

Buy it now

I honestly have purchased this exact product from another store however I just had to review. It is amazing!! I have thousands of stink bugs and everything else in my house. The house sat empty for years. This will take a few days to kill but it kills everything. I put in under my couch cushions, mattress, in christmas/ all storage containers. It is safe for pets and kids so literally have it everywhere. I have it in my exhaust fans, vents and crawl spaces. Buy it!!

Harris Diatomaceous Earth

This is my second bag of Harris Diatomaceous Earth. I bought my first bag in May 2019 to battle squash bugs (worked great for that, when pesticides DID NOT); then I started using it for ants. So, the 10.5# bag got me through 3 garden seasons, and I needed more. I wanted the same brand but could not find it in stores (clerks said that it sells out as fast at they get it). So glad to find it at Chewy!

Good stuff

This food grade diatomaceous earth came with a "duster" that is easy and works great! I spread this product around outside where my cats have a "catio" to try to cut down on fleas/ticks.
