Honey B Healthy is a feeding stimulant that should be added to your sugar syrup or winter patties when feeding your bees. It can be used in a sugar syrup spray for collecting swarms, spraying to calm the bees during inspection and spraying new foundation to help encourage bees to draw out the comb. Honey B Healthy contains essential oils including Lemongrass Oil and Spearmint. One 16 oz. bottle will last a hobbyist 2-3 years when stored properly.
