Bulk Pro Winter 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. Simply spread the mix over your top bars or make your own patties on wax paper. Bulk Pro Winter patties are not separated by wax paper. As warmer weather approaches switch to a pollen substitute patty such as Ultra Bee or Bee Pro® Patties which will provide both carbohydrates and protein for brood rearing.
