Key Features to Look For
When you shop, look for these key features:
- Long-Lasting Protection: Some repellents work for hours. Others only last a short time. Choose one that works for the amount of time you need.

Important Materials to Consider
Repellents use different materials to keep flies away. Here are some common ones:
- Pyrethrins/Pyrethroids: These are natural or synthetic insecticides. They kill bugs on contact.
- DEET: This is a common ingredient in human insect repellents. It works well but some horses may be sensitive.
- Citronella: This is a natural oil. It has a pleasant smell and repels insects.
- Essential Oils: Some repellents use other essential oils. These can include lavender, tea tree, or eucalyptus.
- Oil-Based Formulas: These formulas help the repellent stick to the horse’s coat longer.
Factors That Improve or Reduce Quality
Several things affect the quality of a horse fly repellent:

User Experience and Use Cases
How you use the repellent matters. Consider these use cases:
- Daily Use: For horses that are outside a lot, use a repellent every day.
- Turnout: Apply repellent before letting your horse out in the pasture.
- Riding: Use a repellent before you ride. This will help keep flies away.
- Specific Areas: Concentrate on areas where flies bother your horse the most. This might be the legs, belly, or face.
