  1. Turns out we've had the wrong assumption about how Varroa mites feed off bees.....

    Varroa and using Burgess Insect fogger

    I have been experimenting with a fogger using mineral oil and wintergreen. Trevs Bees has a good YouTube post about this with Neil Farrer in Wanganui Its been relatively successful with a consistently low mite count. I imported the fogger from the US for about $150. I was planing to try using it with Oxalic Acid however getting the alcohol is next to impossible as you need very high grade alcohol (Yet its available over the counter in the US!). The best place to get the alcohol is a distillery but its not cheap, about $75 per 500ml. There are also issues around keeping the fogger clean as the acid is very corrosive. I wouldn't use meths as this is essentially alcohol that has been coloured and flavoured ("denatured" to use the technical term) so may have an effect on the bees. I'd be interested to know how you get on if you use this. I couldn't find much information about the use of meths or isopropyl alcohol in foggers.
  3. Makes for an interesting read... https://www.israel21c.org/unique-israeli-research-reveals-why-honeybees-are-dying/ “Bees are dying from all kinds of reasons,” he tells ISRAEL21c. “There is an ongoing debate as to the causes. We believe there are multiple causes and they all synergize. The three most important factors are the use of pesticides and poisons in the environment; the Varroa mite and the viruses it transmits; and the lack of proper nutrition or malnutrition” caused by shrinking amount and variety of wildflowers.

    New Varroa Treatment?

    I've read about this.. wonder how effective it is. It seems to treat incoming mites but not in the hive itself?
  5. Hi Has anyone used one of these? Is it effective? How much does a unit cost? It looks well thought out and well engineered. One Stone Thanks

    NZBF non waxed frames?

    The frames need to be waxed to work, otherwise the bees wont have anything to build on As usual there's an awesome video by @Trevor Gillbanks at [media] [/media]

    Some advice needed for cut out

    Thanks Trev .. I had an idea that this would take some time to "migrate" the bees to the new box. Happy to take the time.

    Some advice needed for cut out

    Wow! Thanks for your solution @Trevor Gillbanks , this is what years of experience, wisdom and ingenuity look like! I'll gather some helpers (I think this is more than a one man mission), get my equipment together and get this done. I'll also take some photos and post these as well. It will be a good challenge. Then I will attempt option 3 above on the same day! Thanks Trev!!

    Some advice needed for cut out

    Hi @Trevor Gillbanks The design of the hive is quite "unique" . The boxes are not the same dimensions as a Langstroth. I understand in talking to the son that his father made his own frames and boxes. From what I could make out the frames are like normal Lang frames but only about half the length - almost like a mini nuc frame. There are 20 to a box with a central support rail running down the middle of the box and one end of the frame sitting on this rail and the other end sitting on the super. The frames are there in the supers further below the burr comb - I just couldn't get to them. They will almost certainly be propolised in - and I think they would almost be destroyed in the act of removing them from the hive. The state of the wood is such that I think I'd be left with a pile of wood after the job and nothing (except for the burr comb and bees) that could be used in a new hive. A bit of a challange! @Trevor Gillbanks , do you have any thoughts about timing? Should I attempt this sooner rather than later, or wait until the weather is warmer and the queen in starting to lay?

    Some advice needed for cut out

    Thanks @Martin Garside , I have assumed that there will be a varroa issue and therefore I will treat regardless. I will definitely be checking for AFB and if found, burn the lot.!
  11. Hi I need some advice on what to do with a rescue / cut out I was called to have a look at an "old hive". It turns out that an old bee keeper used to live at this house about 7 or 8 years ago. His son gave me a call to come and have a look. There were a whole heap of hives at the back of his place, most in an extreme state of disrepair. One of the hives had attracted a swarm and they have taken up residence, for what seemed to me to be at least one season, may be more. I tried opening as much as I could however most of the supers are very tightly packed and if I started dismantling the hive I would need to have somewhere to house them straight away. I decided just to have a look as best I could and reassess what to do then. I did lift the lid and found a lot of burr comb throughout the top box. It was laden with honey and seemed to go down a few supers. The bees seemed quite happy. There wasn't a large amount of activity and it didn't seem that the population was very large. I was doing this about 9am, so not in the middle of the day. So what now?? Should I: 1. Do a cut out now, dismantle the hive and get it into a box. Take out the comb and use rubber bands to place the comb into a frame, relocate and feed and treat them for varroa? 2. Leave this at the moment (the owner is in no hurry) and come back and cut this out in mid to late September when the hive will be starting to grow and things will be getting warmer. 3. Go down to the local for a beer? Some photos are attached Any thoughts, wisdom and insights would be greatly appreciated!!
