Is this safe to use around pets and chickens?

It is food grade and OMRI-listed, and owners commonly dust coops and bedding with it. Keep it out of eyes and lungs, and follow the label.

Does it work after it rains?

No. Diatomaceous earth only works dry, so reapply after rain or heavy dew.

Ten pounds of 100% ground freshwater diatomaceous earth and a powder duster. There are no additives.

How is it different from pool-grade DE?

Pool-grade DE is heat-treated and not for food or feed use. This is uncalcined food grade material.

Can I mix it into soil or feed?

The label covers feed supplement and dusting uses. Follow the label rates rather than guessing.

Does it kill bed bugs?

It can help against crawling insects, but it is slow and only works on dry surfaces. It is not a fast knockdown.

Our take on the Harris Food Grade Diatomaceous Earth Feed Supplement, 10 Pound Bag with Applicator

Harris Food Grade Diatomaceous Earth is a 10-pound bag of 100% ground freshwater fossil shell flour with no additives, listed by OMRI for organic use. It comes with a powder duster for applying a fine dusting. It suits gardeners and pet owners who want a mechanical, non-chemical powder for pest control around plants, coops and stored areas. Against liquid insecticides it offers no mixing and no chemical residue, but it must stay dry to work and is slow-acting compared with sprays.
