Evolve is a broad-spectrum wormer & boticide for horses. Evolve has an easy-grip, ergonomic handle so you can easily handle the syringe, no matter how big or small your hands are. When your horse pauses for that split second, you’ll be ready!  It also has an orange flavour that horses love. There is a much lower chance of them spitting it out (or on you!) and wasting the paste.
