Oxalic Acid by Sublimation

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.

5ml per seam. Liquid Oxalic Acid being dribbled on each seam of bees

Carefully done

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.

Sublimation by heating Oxalic Acid crystals in a pipe turns to gas to kill Varroa

Treating the hive

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

The white vapour working nicely.

That’s enough

Everyone watching carefully

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