We’ve had a cold winter here, and we’ve had few opportunities to open up our hives to check on the bees.
It depends on which expert you are asking, but you should only open up a hive if its above about 45F. The rule I’ve read is if you have to wear a heavy jacket, you should not be opening up a hive.
Why open up a hive? Many hives perish in late winter or early spring when they may have run out of food. You want to get a quick peek to if there is food in the comb and if they bees are alive.
After reading and talking to our bee mentors, we decided to slip some fondant into our hives, as well as new grease patties. Fondant can be bought at a bakery supply or some craft stores, or you can make it yourself. There is a good discussion of making fondant on the Bee Source forum here. Pressed for time, we picked up some fondant at a craft store.
We finally had a day where the weather was in the 50s F, we opened up our hive at Maple Knoll Farm. We found a lot of dead bees on the bottom board, and we cleaned these out. The bees were out, already bringing in pollen ( we think from maple trees ), and they were entering the hive through the small gap in the inner cover.
To put the fondant on top of the frames, I built a simple spacer to allow the fondant to sit on top of the top super. We did a quick check of the frames in this top super – do not pull out the frames, just look down into them – and we found ample food in the comb. We decided to add the fondant and a grease patty just to be safe.
We watched the bees, and despite us cleaning out the dead bees from the bottom board, they continued to use the inner cover entrance.
A few days later we decided, since it had been so warm, to put a sugar feeder on top of the hive, with a 1:1 sugar syrup ( 1 lb of sugar to each 1 pint of water ). We pulled off the polystyrene and inner covers to find they bees had barely touched the fondant. They had been using the grease patty.
We left the fondant and spacer on, then put on the sugar feeder. We saw the feeder had warped, and there were gaps along the edge that mates with the hive body. The honeybees were trying to get into the hive between the feeder and the spacer. ( When adding a sugar feeder to the top of the hive, you do not use the inner cover, as it would allow bees to get into the syrup reservoir and drown. )
Remembering in some of my beekeeping books, people do drill entrances into upper hive bodies, i opted to drill a hole in the spacer to allow the bees to enter the top of the hive. I also screwed the warped edges of the feeder into the spacer.
All the time we were at the hive, the bees were bringing in pollen, which i was suprised by. I’m thinking it was probably maple tree pollen and some other early flowering plant that was a nice yellow color, perhaps pussy willows.
Each hive got a gallon of sugar syrup, as well as leaving the fondant on the hive. This week I will probably remove the fondant and top up the sugar syrup.
