Since our summer weather has been rain, rain and more rain--and the hives have little to no honey stores, I started feeding them. I have seven hives and I have poured 15+ gal. of sugar water (10lb. sugar to 2 & 1/2 qt. water) into top hive feeders and they have eaten it in less than 10 days! Our weather has been hot (95*+ and very humid with little rain for a week). The bees are able to forge daily but they are taking the sugar water. Do I keep pouring the feed to them? How long should I continue?

Is there a source for sugar water already mixed up???? (I am buy sugar at Walmart 5lbs for 1.82)Thanks for the help Debbie
