Nor-Feed Nor-Mite is a plant-extract-based red mite repellent for poultry. When added to the hens' feed, it helps to manage the growth of populations of red mites. It is a formulated with cloves (Eugenia caryophyllus) and lemongrass (Cymbopogon nardus) extracts. Nor-Mite repellent components are spread by the animal (via its droppings) to repel the red mites. Repelled from the chickens’ blood, their only source of food, the red mites cannot reproduce at their usual rhythm and their population decreases drastically.
