Does Diatomaceous Earth Kill Fleas?

Diatomaceous earth is one of the most popular flea remedies available today. It’s safe, pesticide-free, and easy to apply. It is a powdery substance made from fossilized diatoms that contain silica and other natural minerals. The particles of diatomaceous earth are sharp and have a drying effect, making them a safe and effective way to kill fleas.

You can purchase diatomaceous earth as a powder or a spray. To use it properly, you should carefully follow the directions on the label. Apply it to your carpet and leave it on for a few hours before vacuuming it. If you don’t vacuum immediately after applying the powder, it can attract new fleas. This means you should make sure that you remove any leftover diatomaceous earth from your carpet before you vacuum.

If you want to use diatomaceous earth on your pets, you should make sure to use food-grade diatomaceous earth, which is labeled “Generally Recognized As Safe” by the FDA. It contains 0.5-2 percent crystalline silica. Non-food-grade diatomaceous earth contains more than 60 percent crystalline silica, which makes it toxic for mammals. While food-grade diatomaceous earth may kill fleas in certain cases, it is not the best flea control option.

Diatomaceous earth is not recommended for use on puppies and dogs. Although DE kills adult fleas, it has no effect on the eggs, larvae, and pupae.
