Diatomaceous earth (DE) is gaining popularity as a natural method for fly control around horses. But what exactly is it, and how effective is it? This article dives deep into using diatomaceous earth for fly control in horses, exploring its benefits, drawbacks, and how to use it safely and effectively.

Understanding Diatomaceous Earth and How It Works

Diatomaceous earth is a fine, powdery substance made from the fossilized remains of diatoms, tiny aquatic organisms. While it may feel soft to us, DE is microscopically sharp. These sharp edges work mechanically to kill insects.

When insects come into contact with DE, the sharp edges cut through their exoskeleton, leading to dehydration and death. DE also absorbs lipids from the waxy outer layer of insects’ exoskeletons, further contributing to dehydration.

Benefits of Using Diatomaceous Earth for Fly Control

  • Natural and Non-Toxic: Unlike many chemical insecticides, DE is a natural product, making it a safer option for horses, humans, and the environment.
  • Broad-Spectrum Control: DE is effective against a range of insects, including flies, fleas, ticks, mites, and lice.
  • Cost-Effective: DE is relatively inexpensive compared to some other fly control methods.
  • Long-Lasting: When kept dry, DE can remain effective for several months.

How to Use Diatomaceous Earth for Horse Fly Control

Always use food-grade diatomaceous earth for applications involving animals or around areas where they graze.

  • Dusting: Sprinkle a thin layer of DE in areas where flies congregate, such as stalls, bedding, manure piles, and around water troughs.
  • Horse Treatment: You can apply DE directly to your horse’s coat, but always use caution around their face. Avoid getting DE in your horse’s eyes, nose, and mouth.
  • Feed Additive: Some horse owners add a small amount of food-grade DE to their horse’s feed to help control internal parasites. However, it is essential to consult with your veterinarian before adding DE to your horse’s diet.

Precautions and Considerations When Using DE

  • Dust Inhalation: Avoid creating excessive dust when applying DE, as it can irritate the respiratory system of both humans and horses. Use a dust mask and ensure adequate ventilation when applying DE.
  • Dry Application: DE must remain dry to be effective. Damp or wet DE will not control insects.
  • Storage: Store DE in a dry, airtight container to maintain its effectiveness.
  • Veterinary Consultation: While DE is generally safe, it is always a good idea to consult with your veterinarian before using it, especially if your horse has respiratory problems or allergies.
