A simple morning spray can make the whole day feel easier for both horse and rider.
"Four summers I watched my gelding rub himself bloody. Four summers I stood at the paddock fence apologizing to him. I tried every spray on the shelf. I started Divolli in May. By July his mane was growing back for the first time since he was five. I cried the first morning I saw it."

"I'd stopped riding her completely. She would bronc every time a horsefly came near us — bucking, bolting, totally unrideable from May to October. Last Saturday we went two hours on the back trail. She walked through a swarm of deerflies and barely flicked her ears. I have my horse back."

"He's been managing her insect bite hypersensitivity for six years. Last appointment he stopped mid-exam and said he couldn't believe it was the same pony. Coat clean, ears healed, no welts on her belly. I told him about the formula. He wrote it down. Honestly? Neither of us could believe it either."

What is it made of?
What is it made of?
Zyrix uses four plant-derived essential oils: citronella, peppermint, tea tree, and lavender. The formula is water-based with a natural emulsifier so it sprays evenly and stays on the coat without synthetic insecticides or artificial fragrance.
How do I use it?
How do I use it?
Spray once each morning before turnout. If insects are heavy or the weather is especially humid, apply a second light coat later in the day and gently brush it into the hair.
Is it suitable for sensitive skin?
Is it suitable for sensitive skin?
Yes, it is designed to be gentle enough for horses and ponies with sensitive skin. If your horse is new to botanical sprays, we recommend testing a small area first.
