This Diatomaceous Earth is safe to use for pet's and children.

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.

Diatomaceous Earth May Have Helped Get Rid of Bedbugs

I was having bedbugs in my recliner, and I used diatomaceous earth (DE) to get rid of them. I puffed DE around but, in the end, I had to throw the recliner away. The bug-biting stopped, and the exterminator could not find any bugs in my apartment. Did the DE help in any way to get rid of the infestation? I can't be sure but I feel confident that it may have. I have a one-bedroom apartment, and four pounds of DE was more than what I needed. I just didn't know how much to buy.

This Worked!!!

My cats have been covered in fleas this year. Worse than any other year. I've tried natural remedies, chemical remedies and nothing was working. I sprinkled this on their fur around their neck, down their back and along their tail. I use a flea comb to check for fleas and they have gone! If I do find a stray flea, I sprinkle on a bit more of the powder. Finally something that worked with no adverse affects.

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!!
