Glossary
A protein-rich supplemental feed shaped into flat patties and placed directly on top of the brood frames. Pollen patties provide the amino acids bees need for brood rearing when natural pollen sources are scarce or unavailable.
Honey provides carbohydrates (energy), but bees need protein for brood rearing. Nurse bees consume large quantities of pollen to fuel their hypopharyngeal glands, which produce the royal jelly and brood food that nourish developing larvae. Without adequate protein, nurse glands atrophy, brood food production drops, and the colony cannot raise healthy young bees. A colony with plenty of honey but no pollen will stagnate.
Commercial pollen substitutes are formulated using brewer's yeast, soy flour, egg powder, and other protein sources blended with sugar syrup and shaped into patties. They do not taste or smell like real pollen (and bees know the difference), but they provide the essential amino acids bees need when real pollen is unavailable. Some patties are fortified with vitamins and lipids to more closely match natural pollen's nutritional profile.
True pollen patties contain actual collected bee pollen mixed with sugar syrup. These are more readily accepted by bees but carry a risk: pollen can transmit diseases (particularly Nosema spores and chalkbrood) between colonies if it comes from unknown sources. For this reason, many beekeepers prefer pollen substitute over raw pollen from unfamiliar origins.
Pollen patties are most useful in late winter and early spring, when the queen is ramping up egg production but natural pollen sources have not yet begun blooming. Providing protein at this critical juncture can accelerate spring buildup by several weeks, ensuring the colony hits peak population in time for the main nectar flow. Remove patties once abundant natural pollen is available, as bees strongly prefer the real thing.
For short periods, yes. Commercial pollen substitutes provide essential amino acids that support brood rearing. However, natural pollen contains a wider array of nutrients, lipids, and compounds that substitutes cannot fully replicate. Patties are a bridge, not a permanent replacement.
Place the patty directly on top of the brood frames under the inner cover. Cut a slit in the paper or plastic wrapping to expose the surface. The bees will consume it from above. Start with a half-patty on smaller colonies to avoid waste and small hive beetle attraction.
