Oxalic Acid Demo

Oxalic Acid Treatment against Varroa

The trickle method of Oxalic Acid Treatment treatment  should be used when only the phoretic stage if the mite is present.  Tests have shown that  the active ingredient does not penetrate the larvae in sealed cells.   The procedure is carried out  when the colony is broodless in the middle of  winter.  It can also be give to newly hived swarms at the same rate of 5mls per seam of bees using in our climate a 3.5 - 4.5 % OA  in 6% sucrose solution.

Mini Mating Nucs

These are illustrations of  two popular mini mating nucs.  The Apidea and the Top Bar Warnholtz/Kerchainer model.

The Apidea is smaller in volume with initially 3 small combs in plastic frames.  It requires fewer bees to stock it at first but can soon become over crowded.


The Warnholtz is slightly larger in volume and fitted with top-bars.  It has fewer parts but must be provided with a plastic sheet to act as a quilt.

Queens mate and come into lay quickly and have to be moved on quickly from both these hives.  The queenless colony  can be given another cell after about 24 hours but should be carefully examined during the next 7 days for rogue queen cells of their own.

The Warnholtz is easier to clean and steam sterilise after use.

In these two videos by Eva Bakkeslett a former student in media production at Schumacher College, Dartington,  Glyn Davies explains the structure of the honey bee brood nest. Glyn and colleague Bob Normand, are seen managing a queen rearing colony.  There are some excellent shots of a queen searching for a suitable cell then laying an egg.  There is also the clear formation by her attendants of a surrounding daisy-pattern ring and also shots of the remarkable foraging bees performing the bees dances which communicate the location of the nectar source they have been visiting.

Here Glyn Davies and Bob Normand complete their management of a honey raising colony and Glyn discusses the process of honey extraction with Eva Bakkeslett.

In the final sequence Brian Goodwin of Schumacher College ponders the way that the industry and organisation of the honeybee life history helps him to contemplate a life of meaning as contrasted with a meaning of life.
