Jeff recommends installing a two inch strip with every bee package! Made with 15% real pollen, these protein patties are readily accepted by bees. Stimulates brood rearing to nurture the hive to maximum strength for the honey flow. Notes on Use: Feed these patties in the early spring about six weeks prior to the major honey flow to stimulate brood production. Feed 1-2 patties on top of the brood frames, in contact with the cluster for maximum consumption. Stop feeding patties when plenty of natural pollen is seen being brought in the bees. Do not use pollen patties in the winter! Pollen stimulates brood rearing and only should be done in early spring when pollen is not present. Unused patties should be frozen to preserve freshness. Ingredients: Sugar, Soy Flour, Brewer's Yeast, Water, 15% Pollen. (Pollen was irradiated to prevent any disease transmission.)
