HerbaMite is 100% natural and improves the natural resistance of all avian species against red mites. It stimulates an immune response in birds, helping create a natural repellent in the blood which is indigestible for mites. As blood coagulates within the mite, it dries and can no longer affect the birds. HerbaMite does not kill red mites directly. The natural repellent created in the birds blood due to the ingestion of HerbaMite repel red mites. They can no longer feed and do not pose a threat to the birds. This is administered through drinking water.
