Pyranha Nulli-Fly, manufactured by Pyranha Products, is a water-based insecticide that kills and repels flying and biting insects from animal quarters, horses, and dogs.

This unique formula contains 3 active ingredients, making it 33% stronger than other economical fly brands with minimum application effort. This effective fly repellent is also less likely to attract dirt and debris on the animal's coat long after Pyranha Nulli-Fly has dried.

Pyranha Nulli-Fly is an ideal, long-lasting fly and debris repellent that guarantees results from the round pen to the show ring. With its unique formulation, it does well against pests but does not harm horses with sensitive skin.

How to Use

  • Step 1: Determine whether you use a direct wipe-on or trigger spray application. Next, remove excess dirt and dust on the animal.
  • For direct wipe-on applications with Pyranha Nulli-Fly, thoroughly brush the horse to remove excess dirt and dust. Extremely dirty horses should be shampooed, rinsed, and allowed to dry before applying a wipe. Use a sponge or clean, soft cloth or mitt. Apply Pyranha Nulli-Fly liberally (1 to 2 ounces) over areas to be protected. Pay special attention to the legs, belly, shoulders, neck, and facial regions. Do not get in the eyes and mucous membranes.
  • Step 2: For trigger spray use with Pyranha Nulli-Fly, apply 1-2 ounces of this product as a light spray mist to coat while brushing lightly against the lay of the hair. Do not spray on eyes and mucous membranes. Apply with a sponge or soft cloth around those areas.
  • Step 3: For use on dogs to control fleas with Pyranha Nulli-Fly, apply as a spray starting at the tail, then spray over the entire hair coat while moving the dispenser rapidly. Apply the spray lightly over the entire body with even coverage until the tips of the hair are moist. Do not spray into the eyes, face, or genitalia. Using gloves, rub the product into the coat by running the hair so the product reaches the skin. Allow the dog to air dry or blow dry. Do not towel dry. Do not reapply more than once every 14 days.
  • Step 4: For use in listed animal premises with Pyranha Nulli-Fly, spray in areas where insects congregate—direct spray to contact insects for rapid knockdown and kill. Spray around door facings and screens to render the area unattractive to insects. This helps repel insects and prevent entrance to the building.
