Colonies with brood patterns like this in early fall often do not survive winter.īees will cluster around the queen in the bottom brood box as temperatures drop. A spotty brood pattern, as seen here, suggests a failing or missing queen or a colony with potentially bad health. Late summer and early fall bees can be fed abundant protein and store many food reserves in their body to feed to late winter and early spring brood.įigure 3. Most races of bees cover stored pollen with honey, often sealing the honey, making it hard to measure the amount of pollen stored within a colony. A typical colony will naturally create this brood/pollen/honey pattern. The pollen-filled cells, in turn, should be surrounded by cells filled with capped honey. Brood should be located in the bottom hive body (brood box, or deep super) and surrounded by cells filled with pollen. Care must be taken if this path is chosen because diseases may be spread from one colony to another through infected honey or frames.īeekeepers must also ensure that the honey stores are properly located within the hive.

An alternative to supplementing with syrup is to supplement weak colonies with extra honey from stronger colonies. The best way to learn about local honey flows in your area is to contact a horticulturalist at a local county or state Extension center or mentor with an experienced beekeeper from your immediate area. This flow may allow the bees to store enough reserves, but honey production should be monitored carefully by the beekeeper during this time. Some colonies may be located in areas that experience a fall nectar flow from goldenrod, aster, or other fall-blooming plants. Other feeders also can be used to deliver sugar or high fructose corn syrup to colonies. Hives getting supplemental sugar syrup through top feeders. If the hive is easy to lift, then it probably needs more food.įigure 1. If the hive is difficult to rock forward with one hand, then it likely has enough food reserves to survive winter. To conduct a lift test, attempt to lift the colony with one hand using the handle on the back of the bottommost super. Colonies that have enough honey or stored sugar syrup to survive winter will pass the "lift" test. Bees will store the syrup as a substitute "honey" for use throughout the winter. If there is not enough honey stored in the supers for the winter after the removal of surplus honey by the beekeeper, the hives can be supplemented with a mixture of high fructose heavy corn syrup or, better yet, sugar syrup (2 parts sucrose sugar:1 part water by volume) in the fall. Generally, there should be about 90 pounds of honey reserves for a colony in the North, because bees will not be able to forage in the winter.

One of the leading causes of colony death during the winter is lack of food. Beekeepers must ensure that there are enough food stores for the entire winter and that the colony is healthy and strong. In northern climates, preparation usually starts in August/September, though it may begin earlier depending on the location. Preparation of the colony for winter must begin in late summer or early fall. Bees naturally prepare for winter on their own, but they may need the assistance of a beekeeper to ensure survival through winters in extremely cold climates. Of course, there will always be some colony loss, but with good management, losses often can be reduced to below 10%. Special preparations must be made during the fall to ensure that colonies survive the winter months with minimal loss. This can be especially challenging to beekeepers in extreme northerly climates (such as Alaska and northern Canada). One of the many challenges beekeepers face is minimizing honey bee colony losses during winter.
