Christmas – Bees and Wintering

Christmas is one of the four quarter days which mark the changing of the seasons.

The four quarter days are:

  • Lady day or the Feast of the Annunciation 25th March;
  • Midsummer’s day around 25th June;
  • Michaelmas 29th September;
  • Christmas 25th December – lest we forget – fat chance.

They all approximately coincide with either an equinox or a solstice.

Mid-winter Varroa Treatment – December 2013

Copyright © Beespoke.info, 2014. All Rights Reserved.

Trickle treated 35 hives of bees with oxalic acid for Varroa today at 4 apiary sites. The temperature was 6 degrees, windy and beginning to rain. It took from 1.15pm to 4.15pm including travelling time so it has to be said it is the quicker of the two methods. If we had only the one Varrox Vaporiser it would have taken 10 minute per hive – which is nearly 6 hours and without the travelling time. Continue reading Mid-winter Varroa Treatment – December 2013

Winter Oxalic Acid Varroa Treatment

When the shortest day is upon us there is a brief broodless period in the honeybee colony. This is the time conditions are right for oxalic acid treatment. There are two reasons for this:

  1. When a colony is broodless, all the Varroa are at their most vulnerable out there in the open, either on the bees or creeping about on the comb – Varroa are protected from the effects of oxalic acid when they still inside the cells of the brood nest;
  2. Oxalic acid can damage open brood so these effects are minimal when there are no or few larvae.

On December 9th 2013 the bees were flying quite strongly and still working the last of the ivy and the Mahonia but there has been little activity since then. Any eggs laid during that spell of mild weather will have hatched by the end of December so that might be the best time to treat.

The following methods can be used during any broodless period, even in the middle of summer, but supers need to be removed. Click here for more about summer oxalic acid treatment. Continue reading Winter Oxalic Acid Varroa Treatment
