Early Cold Snap, Seeking Sunlight, A Quilted Top Cover.

I've had my 8 frame nuc at my parents' place for a week now and the cool weather has hot with vengeance: the coldest May maximum temp for decades.  The snow fields received a drop of 50cm of snow,  five weeks before the start of the season. 
I checked my baby hive through the week and it was very busy with bees added lots of sealed honey.  In fact it was too busy to lift a frame without upsetting them.  They're a lively enough bunch anyhow. 
But it was concerning to see them not working this afternoon,  knowing they were in "heat generation mode" and using up honey stores already,  before winter is officially underway. 
I also noticed that the sun goes of the hive in the early afternoon.  So,  I now want to move them out of the shade about 2 minutes and add a quilted cover.  This is just a standard lid,  hessian tracked across it's bottom and filled with wood shavings.  This adds insulation and absorbs moisture which is manufactured by the bees heating the hive in cold conditions.  Moisture is destructive to honey stores and the structure of the hive.

More Spring Bee Lessons

 Well my bees beat me up these last two weeks. To be fair though  it was mostly my fault. So,  I started with radix hives; two at coastal Merewether and two on my property near Paterson.   Obviously the Merewether hives produced through winter and with a bit of an up-change in the weather they needed space for brood and honey.  This caught me out (Lesson 1: don't procrastinate or aim to do the least amount of work. In other words don't be lazy.)  I then had to rush around buying and assembling frames. Penders Bees reported that from their orders it's a bumper season. But I  really need to not be so unprepared again.   Adding Supers and extracting helped create space,  but I'll be extracting again very soon with my spanking new machine. Unfortunately in hive #4 the Queen spent the winter above the Excluder and it really knocked them about. Removing the Excluder (which was a third full of dead Drones) got them working ok again.  ...

Swarm Cut Out.

Today's principle task was to participate in my first cut out of a wild bee colony. Leading the extraction was my bee mentor Warren Bee and his neighbour, also experienced extractor, Dave. Well, the colony was hiding in a wall in an abandoned dairy building. Two things straight up to assault the senses, the smell of rear poo (and dust) and a vast number of dead bees. In a north facing wall below the kitchen sink, these bees head cooked in hot weather. The process was to remove all the internal fittings and linings, remove comb and suck up as many bees as possible. Good comb was saved for honey extraction, old comb was trashed. Sucking up the bees was done using a little vacuum cleaning drawing bees through a filtered hive box especially designed for the job. It took about 3.5 hours. I never got stung, so I liked them all. Hopefully, of those that survive this process, they will have a brighter future than their old buddies. PS. As it happens I went to my mentor's yard ...

Transferring a Hive

In early February arrangements were made to meet Warren and see about taking my nuc hive home. I was really excited and nervous about whether I could actually keep some bees because my track record was pretty ordinary. I met Warren late in the afternoon because bees are best transported after dark because they're all "home" and are more quiet. He was tall, and older and seems busy talking and remembering to do stuff. Halfway through saying hello, he waved to a neighbour and took him of to show him a drainage problem, that had shown up during recent much needed rain. He opened his wagon to put stuff in and the forgotten smell of the smoker permeated my life again. The car was neat, but had seemingly everything a beek would need, ready to hand. Little did I know. In the half hour it took to say hello and get moving, Warren plied me with information about bees. I made mental noted on everything. I suspect he was also assessing whether I was up to the task. We drove to a si...
