Dry bee feed usually means one of two things: dry sugar for energy, or a protein “pollen substitute” fed as a powder or patty when natural pollen is scarce. Sugar replaces nectar, while pollen substitute replaces pollen. Knowing which one your colony needs is the key to feeding well.
Dry sugar
Bees can eat granulated sugar when it is spread where they can reach it, which is useful when it is too cold for liquid syrup. A common cold-weather approach is the mountain camp method, where sugar is laid on newspaper over the top bars. It is an emergency or late-winter tool, not a replacement for the stores a colony needs going into winter.
Pollen substitute
Pollen is the bees’ protein, fat and vitamin source, and nurse bees need it to feed larvae. When flowers are not producing enough, beekeepers use a substitute. Substitutes are made from protein sources such as yeast, soy or other plant proteins with added vitamins and minerals, and they come as dry powder or ready-made patties.
- Dry powder can be fed in a protected feeder or mixed with syrup.
- Patties are placed directly over the cluster so bees can reach them without leaving the hive. A homemade patty is often mixed to a texture like wet peanut butter before being placed on top of the frames.
Commercial options include Ultra Bee dry feed and Nutra Bee pollen patties. Read the label for feeding directions, because products differ.
When to feed protein
Patties are most useful in late winter and early spring to support brood rearing before the first major bloom, and during dry spells when forage is thin. Extension beekeeping guidance describes using patties to supplement colonies through winter and late spring. Do not overfeed: colonies that have plenty of pollen coming in will ignore patties.
Real pollen versus substitute
Trapped pollen from outside sources can carry pesticide residues or disease, which is why many beekeepers choose a manufactured substitute. If you do feed real pollen, buy it from a source that tests for contaminants.
Common problems
- Small hive beetles. Patties left on the hive too long can attract beetles. Use small patties and replace them as needed.
- Mold and drying. Remove patties that sour or harden.
- Robbing. Do not spill powder or syrup around the hive.
Bottom Line
Use dry sugar for energy in cold weather and protein patties or powder when pollen is short. Feed small amounts, replace old patties, and confirm your colony actually needs the supplement before you buy it. See our guide to what bee larvae eat to understand why protein matters.
