Why Choose a Natural Fly Spray?

Many fly sprays on the market use synthetic chemicals that can irritate skin or cause allergic reactions. Animals with sensitive skin, like horses and alpacas, often react poorly to these products. Natural fly sprays use essential oils and gentle ingredients that repel flies without harmful side effects. This recipe combines apple cider vinegar, essential oils, and a mild soap to create a spray that is safe and effective.

Using natural ingredients also reduces environmental impact. Chemical residues from commercial sprays can contaminate soil and water. This homemade spray breaks down naturally and is safer for your animals and your surroundings.

Ingredients You Will Need

• 16 oz spray bottle: Use Amber colored glass, HDPE plastic, or PETE plastic (numbers 1 or 2). Avoid other plastics to prevent chemical leaching.

• 1 bottle of TerraShield (15 mL / 250 drops): TerraShield is a blend of essential oils known for repelling insects.

• 1 cup apple cider vinegar: Vinegar helps mask animal scents that attract flies.

• 5-10 drops dish-washing soap: This acts as an emulsifier to mix oils and water. OnGuard Cleaner Concentrate is a good alternative.

  
  

Step-by-Step Directions

2. Add TerraShield: Pour the entire 15 mL bottle into the spray bottle.

How to Use the Fly Spray Safely and Effectively

• Shake before each use: Essential oils and vinegar can separate from water, so shaking ensures even distribution.

• Avoid spraying near eyes: Essential oils and vinegar can irritate eyes. Spray around the face carefully or use a cloth to apply.

• Apply to animals and humans: Spray lightly on the coat or skin, avoiding open wounds or sensitive areas.

• Reapply as needed: Depending on fly activity and weather, reapply every few hours or after sweating or rain.
