Winter treatment against varroa when the colony is broodless. It is over 90 per cent effective.
This guide is based on Danish conditions and rules. Rules, products and timing in your country may differ.
- Timing: usually in December, when the colony is broodless.
- Dose: follow the package leaflet for your product. The dose is given per seam of bees and depends on the product, so count the seams before you start.
- Trickle the solution directly onto the bees in the seams. This can be done even when it is cold.
- Use an approved product and follow the package leaflet. Do not repeat the treatment too soon.
- Wear acid-resistant gloves and safety goggles.
Record the treatment in the app. It will then be included in your medicine log and you will get a reminder to count the mite drop afterwards.
