First, I want to state that I hate feeding bees anytime. That being stated, I placed some high dollar Mann Lake Bee patties on my hive a week ago. Since that time, the temps have been below 40 degrees at night with daytime temps warming to the 50's and 60's. I took a look at the ranch hives today, and the bees have not touched them. Yes, they still have some capped honey, but I thought they would use the patties also. Even with capped stores, they will take some sugar syrup this time of the year, but the patties are supposedly (according to the advertisements) more nutritious than sugar syrup. I thought the patties would help them to build up. The patties are also much easier on the beekeeper. Like I said, I hate feeding as I have never found a satisfactory way to feed bees.
