NBU Warning August 2015 (http://www.bee-craft.com/nbu-warning-august-2015/)
The following warning was issued by the National Bee Unit on 13 August 2015:
In many areas of the UK nectar flows have ceased and reports are coming in from Regional and Seasonal Bee Inspectors of starving bee colonies, where the beekeeper is not aware that the bees are severely short of food, or the colony(s) have already starved to death. It is also apparent that Wasps are becoming populous in many areas and they too are desperate for nutrition so Beekeepers should be mindful of the need to protect hives from Wasp invasion particularly where feeding is taking place in the apiary.
Colonies particularly at Risk are:
• Bee Colonies where supers of honey have been removed this season and no feeding has taken place.
• Splits / Artificial Swarms and Nucleus colonies made up this year.
• Swarms collected this year where little or no supplementary feeding has taken place.
• Firstly – Check all colonies feed levels by ‘hefting the hive’ – Check the weight of the colony by lifting below the floor on both sides of the hive to see how much it weighs (Photograph attached – Hefting a Hive). Where the hive is light, liquid feed should be applied directly above the bees. Remove any supers from above the brood box which are empty or have few bees in them. This will help the bees get to the food quickly.
• Feed can be sugar and water mixed at 2:1 ratio or one of the proprietary ready mixed syrups available from Beekeeping Equipment Suppliers.
• Fondant can be used in an emergency if nothing else is available – but liquid feed will be more appropriate at this time of the season.
• Large starving colonies of bees will take 1 gallon (Approx 5 Litres) of syrup very quickly – smaller colonies ½ gallon (Approx 2.5 Litres) may be sufficient to keep them going, but after feeding heft hives again and check the weight – if in doubt feed some more in a few days time.
