Hopefully the updates will give you some tips and hints about what we can be looking at with our own apiaries.
So what’s the “buzz” down at the apiary this week…
The open apiary sessions have now finished for this year. We will let you know when they are up and running again next Spring 2019.
East Lancs BKA Weekly Hive Opening Report January 8th 2019
A Happy New Year from the Apiary!
Today I carried out the first of three visits to vape the hives in the apiary.
These will be carried out at 5 day intervals to catch as many of the Varroa mites as possible. Last year, this treatment kept the Varroa levels so low that the Bee Unit’s Sentinel Check in May reported negative for Varroa.
I have explained the process in earlier reports but, just to remind you, for each hive:
- The Varroa board is removed (see note D below)
- The entrance is sealed.
- The Vaporiser board is inserted where the Varroa board was.
4, The Vaporiser is charged with 1 gram of Oxalic Acid and inserted into the board and the gaps in the board are sealed.
- The Vaporiser is connected to a 12v car battery.
The Vaporiser melts the Oxalic Acid and the fumes rise up through the hive and eventually condense in the hive.
After about 10 minutes, the battery is disconnected. After a further 10 minutes the Vaporiser can be removed and allowed to cool. If fumes are still escaping at this point, the seals are left in place until it is judged that the fumes have settled. Then the board and the seals can be removed and the Varroa board replaced.
Some points to note:
Check the food before you vape the hive as you don’t want to be removing the roof after vaping the hive.
Remove the mouse guard so that you can seal the entrance with a foam block.
It’s a good idea to check that the entrance is clear of dead bees. The J-type hive tool is excellent for doing this.
When you remove the Varroa board at the start, note where the cappings lie on the board as this will tell you where the bees are clustered (and that they’ve been raiding their stores). You can then clean off the board and replace it after the vaping so you can check the mite drop at the next vaping exercise.
Don’t forget to put the mouse guard back on!
The next vaping exercise will be carried out on Sunday January 13th and the final one on Friday January 18th.
