FYI:
The winter weight is put on the bees 1st and the Fumagillin is fed 2nd so that the bees are medicated at the time of feeding. This method makes the bees use the medicated syrup that is stored in the proximity of the wintering cluster 1st.
Each climatic zone requires a different weight.
Maybe some one can post your feeding question that is near you.
