Our take on the Harris Diatomaceous Earth Food Grade - 2 lbs (includes duster)

Harris Diatomaceous Earth is a food-grade powder made of 100% amorphous silica, sold in a 2 lb bag with a powder duster included. It is used around the home and on livestock to dry out and kill insects such as fleas, ants and roaches by contact, and it can also be mixed into feed as an anti-caking and parasite-control aid for animals. Compared with garden-grade DE, food-grade is the safer choice around pets and poultry, though it is a fine dust that needs care when applying. Owners like the included duster and the simple single-ingredient formula.

Questions and answers

Is this safe to use around pets?
Yes, food-grade diatomaceous earth is generally considered safe around dogs, cats and poultry when used as directed. Keep the dust out of eyes and avoid inhaling it.
How is it different from garden-grade DE?
Food-grade DE is mostly amorphous silica and is purified for use around animals and in feed. Garden-grade can contain more crystalline silica, which is harsher to breathe.
Does it work after it rains?
No. DE only kills insects when dry, so outdoor applications need to be reapplied after rain or heavy dew.
Can I mix it into animal feed?
Yes, it is commonly mixed into livestock and poultry feed as an anti-caking and parasite-control aid. Follow the label's dosing guidance for the animal.
What comes in the bag?
A 2 lb bag of food-grade diatomaceous earth powder and a powder duster for application.
How long does a 2 lb bag last?
It depends on use. For spot treatment of pet bedding and cracks, a bag lasts a while; whole-yard or coop treatments use it up faster.
