Harris Diatomaceous Earth Food Grade, 4 lb.

This diatomaceous earth product WORKS awesome! We sprinkle it around the exterior foundation of our home in the spring, summer, fall, and after a heavy rainfall. This reduces the presence of spiders, ants, earnings, and nasty crawly critters. Had to use it on the front porch in front of the entry door to prevent the little pesky ants from entering our home, and within minutes, the ants vacated! I also find it interesting one can mix a bot of this into the hummingbird syrup to help their eggs to have a sturdy shell. Imagine that! Also can be used with toothpaste to remove stains like coffee, tea, plaque, etc on teeth. Read the label instructions as this product can be irritating to the nose, mouth & lungs. A very necessary & natural product in this chemically laden world. Love this ! So MANY uses!!

I like using this safe pest control method inside and outside. I have pets and this is completely safe. It requires regular reapplication after rain outside but it is easy and cheap to do so. Its essential to buy a bellows-puff applicator to manage the extremely soft powder and to direct it exactly where you want it.

Very very useful product! Kills unwanted bugs - roaches, fleas, spiders, ants…I ingest a spoonful mixed with honey and cinnamon for health purposes.

Good product, and bag size!

I love this stuff. I use it in the garden and I also give it to my pets in small amounts. The sprayer made using on my plants to easy and it really keeps the bugs at bay on my tomato plants!

I was searching for a holistic alternative for fleas, ants and other bugs and found Diatomaceous Earth powder. It's food grade so safe for humans and pets. We used the "puffer" to place it around the inside and outside of our house, especially near the doors and where the pets sleep. We had no issues with bugs until it rained a couple of times and we reapplied it again (recommended). I'm hesitant to give my pets flea medicines since they are essentially poison. This is much safer and we didn't see 1 flea this season. Will buy it again when I run out and continue using this product in the future

I spent hundreds of dollars on sprays, bug bombs, treatments and pills fleas and none of that worked. I heard about diatomaceous earth helping with fleas. I put a little bit on the dogs and then I sprinkled some around my couch and around my house and vacuumed it up and this got rid of the fleas immediately. I 100% recommended. If you're going to be traveling it might be a good idea to put a little powder on your luggage to prevent bringing any critters home with you from vacation. This bag is huge and should last you a really long time.

Updated: The manufacturer sent me the missing duster and all is well. Great product, excellent customer service by the manufacturer.Original review: Note that despite the description stating that a powder applicator is included, I received only the bag of diatomaceous earth. I have contacted the manufacturer to follow up as I can’t use the powder for my needed purpose without an applicator (and there are none locally available where I live, thus the Amazon order in the first place!). So far they have requested my mailing address to send me a duster. Once it arrives, I will update my review.
