Questions and answers
- Which is better for treating a large yard?

- Is the Harris worth the extra money?
- At its low of $9.95 on November 1, 2026 it costs less per pound than most 5 lb bags. At $17.14 on November 2 it is a closer call, so check the current price.
- Do I need to buy a duster with the Natures Wisdom?
- Yes. The Natures Wisdom bag does not include one, so plan to buy a duster or repurpose a shaker.
- Are both food grade?
- Both are sold as food grade diatomaceous earth. Only the Harris states OMRI organic listing and no additives.
- Which is easier to store?
- The Natures Wisdom 5 lb bag. The Harris 10.5 lb bag takes roughly twice the shelf space.
