Honeybee Health: Preparing your bees for winter

September 4, 2020

Did you know that UGVS now offers honeybee health management and veterinary care? With a growing number of small-scale beekeepers and a need for veterinary care, we are excited to get involved in Ontario’s apiculture industry. As always, we are committed to supporting the production of a safe and sustainable food supply and are excited to work with Ontario’s beekeepers!

With summer almost over, it is a good time to start thinking about overwintering your bees. Winter can be a tough time for bees, and it is important to prepare them for the cold months, ensuring you maximize their health and survivability. Here are some recommendations heading into winter:

  • Go into winter with a healthy hive
    • Stay on top of mite numbers as much as possible and if you have not done so already, check for mites in the late summer/early autumn; treat as needed
    • Ensure your queen is laying well and requeen your colony with a young and fertile queen if you have any concerns with the performance of your current one
  • Install entrance reducers and close any screened bottom boards to limit drafts and pests from entering
  • Limit wind exposure of your hives as much as possible by installing wind breaks or moving your hives to a more sheltered area
  • Manage moisture levels in the hive by giving your bees access to an upper hive entrance and tilt the hive forward to enable draining of any water in the hive
  • Feed your colonies with a 2:1 (70%) sugar syrup and ensure they have 3-6 frames of pollen going into winter
  • Treat for American Foul Brood – talk to your veterinarian for more information on this
  • Wrap your hives with winter wrapping or insulation for the duration of winter
