Winter patty (approx one pound). Our Pro Winter feed patties will provide your colonies with food stores when the bees find the cupboards bare. Pro Winter Patties provide carbohydrates and only a very small amount of protein, so your bees won’t be encouraged to start rearing brood too early. As warmer weather approaches switch to a pollen substitute patty such as Ultra Bee pollen patties which will provide both carbohydrates and protein for brood rearing. Winter patty contains 4% protein.
