The BBKA has issued a warning to beekeepers to check their bees for starvation and European Foulbrood during this cold snap.
Emergency feeding may be needed. It would be advisable to check the food levels by opening the hive and making a very quick observation of their store levels.
It is also important to check that hives have small entrances as Foulbrood is about in some areas and small colonies or those suffering disease may not be able to defend themselves from infected intruders if they have a large opening to defend.
