Diatomaceous earth, commonly referred to as DE, is growing in popularity among horse owners. This food grade powder is a natural alternative to traditional pest control. DE consists of the fossilized remains of diatoms, a microscopic sea organism. Your horse can experience internal and external benefits, such as a shinier coat and bone health.

Fly Control

DE creates a dry environment that inhibits flies from breeding. By spreading it throughout your manure pile, you can reduce the number of flies that make it pass the larvae stage.

In general, flies will avoid DE. Feel free to sprinkle it in stalls and around the barn aisle. It’ll also reduce odors that attract flies.

Natural Dewormer

DE works in a few ways to eliminate internal parasites. To begin, it scratches the protective coating of the parasite which makes them dehydrate. It also helps to detoxify the horse’s body, which allows them to have a stronger immune system. Healthy horses are less likely to struggle with parasite overloads.

Consult your veterinarian to determine how much to feed your horse based on their weight.


DE can be used to treat barn cats and dogs as it helps control fleas and ticks. Even a quick dusting of yourself can help prevent ticks from landing on you.

Spills, such as tractor fluids, can easily be cleaned up with DE. It absorbs the substance very quickly.

This powerful powder is definitely worth having around the barn. Make sure to always use food grade!
