Many feed-through fly repellents contain naturally derived ingredients such as garlic and diatomaceous earth, while others use insect growth regulators to help disrupt the life cycle of common flies. Equine dewormers target a broad range of internal parasites that can negatively impact digestion, condition, and overall health.
