Diatomaceous earth is a versatile and eco-friendly product that has a wide range of uses in and around the home. It is made from the remains of diatoms, which are microscopic algae with a hard silica shell. This naturally occurring substance is typically ground into a fine powder, known for its excellent absorbency and abrasive properties.
Using diatomaceous earth can be an effective method for controlling household pests such as fleas, ticks, and bed bugs, as well as for gardening purposes, including soil amendment and as an insecticide. Its natural properties make it an ideal alternative to chemical-based products, providing a safe and sustainable solution for various household needs.
When choosing diatomaceous earth, it is essential to pay attention to the product’s quality, purity, and specifically whether it is food-grade or not. Food-grade diatomaceous earth is safe for human and pet consumption and is the preferred choice for most home applications, whereas non-food-grade varieties can be toxic when ingested. Particle size, packaging, and source of origin are also factors to consider, as these can affect the effectiveness and safety of the product.
With these factors in mind, we spent a significant amount of time researching and comparing different diatomaceous earth brands to bring you our top five choices that excel in quality, effectiveness, and safety.

Buying Guide
Quality of Diatomaceous Earth
When choosing a diatomaceous earth brand, it’s essential to look for a high-quality product. To ensure the effectiveness of the product, make sure it’s made from 100% freshwater diatomaceous earth. This type has been proven to deliver the best results in various applications, such as pest control and natural health supplements.
Food Grade vs. Non-Food Grade
There are two types of diatomaceous earth products: food grade and non-food grade. We recommend choosing a food-grade product, as it is safe for human consumption and has undergone more rigorous quality control. Non-food grade products are more suitable for industrial and agricultural uses, but not for personal use.
Particle Size
The particle size of diatomaceous earth can affect its effectiveness. Finer particles have more surface area and are generally more effective. However, they can also be more challenging to work with, as they can create dust and irritate our respiratory system. Consider your intended usage and choose a particle size that meets your needs without causing too much dust.
Packaging and Storage
Diatomaceous earth should be stored in a cool, dry place, away from direct sunlight. Brands that offer high-quality packaging, such as resealable bags or sturdy containers with tightly sealed lids, are preferred as they can help maintain the product’s quality and effectiveness.
Available Sizes
We might have different requirements depending on our intended usage. Choose a brand that offers various sizes or quantities of diatomaceous earth to ensure we get the right amount for our needs. This will help us avoid wasting product or buying more than we need.
