Before the approach of winter, the quantity of stocks must be checked in order to verify that the swarm has enough resources to survive this season. In case the stocks are low, it is possible to supplement the bees’ feeding by using special candy that can be placed directly on the wire netting. In this way, bees will pick it up by staying inside the nest, without having the need to go up to the honeycomb. During wintertime, it is good not to open them or to open them as little as possible: bees keep warm the inside of the hive with their own movements and opening them during a very cold day could cause serious problems to the colony.
