Treating the hives with Oxalic Acid by Sublimation 10 members getting instruction/demonstration of the method of application.
30th November 2019. Peace and quiet and all secure at the Laddingford Club Apiary
Wire netting held in place by the crossed sticks and hive strap to keep the woodpeckers off the hives.
Lovely sunny day. But cold. Bees tucked up and quiet
First meeting January 2020. Instructions by James showing the various methods of treatment.
showing the gear needed
5ml per seam. Liquid Oxalic Acid being dribbled on each seam of bees
Julian our Deputy Apiary Manager showing his own vapour pipe with gas valves added.
A good view of the top viewing box with a transparent sheet so the gas can be seen acting on the bees.
Crystals put into the pipe, they are heated and turn to gas and you can see the white vapour coming out of the pipe across the tops of the frames treating the bees and killing the varroa
An electric wand that is connected to a car battery that sublimates the crystals into a gas which you can use rather than the copper pipe method.
Chris showing a vapour gun that is used commercially to treat many hives one after the other quickly.
The New Vapour Gun used by Bee Farmers is very quick and can treat multiple hives
January 2020 Each member, mostly beginners, get a turn to treat a hive, learning the technique so they can treat their own hives.

The top eke has a transparent plastic top so you can see the vapour working
The white vapour working nicely.

Everyone watching carefully
Note the new multi purpose eke on top that can be used on a National and Langstroth hive, invented by Jules.
