Works great!
I own a Little Free Library, and I use this product to keep ants and other insects from getting inside and destroying the books. I sprinkle it around the bottom of the post the library is nailed to, and it’s worked like a charm for the past two years. Highly recommended.

4.0 out of 5 stars Good value, but poor packaging!
Reviewed in the United States on July 20, 2023
I ordered the 4 lb bag for our garden, as we’ve been getting plenty of rain in Connecticut this year! I liked that it came with the plastic applicator. But, the packaging is a bit of a nightmare! The applicator was inside the product packaging. Convenient for the manufacturer, but makes a bit of a mess and waste! Although easy enough to assemble and use, with provided instructions. I’m a bit concerned as to how well the rest of the product would last, when the Zip Lock strip is a nightmare to close…

Will update my review in a month!

With planting season coming to an end, I have to say that this DE provided us with what I consider a great harvest this year, with little to no insect or caterpillar damage to our crops. I was very careful not to apply on the flowers to prevent harming the pollinators. Had to keep reapplying since we had so much rain this season, but have over 3 lbs leftover to carry over for next year. I hope this will survive storage, as I’ll need to double bag to original plastic container.

I give it 4 stars, well worth it to protect your vegetables and fruits!
