Changes

If there are dirty frames that are contaminated with mold or feces after overwintering, they should be replaced with new clean [[built wax combs|built wax combs]]. Following the number of bees and looking for abnormalities in bees, brood, smell etc. during every inspection gives you continual information about the bee colony’s health. Observing the flight entrance and the behavior of the worker bees tells you the bees’ foraging ability and harvest at the time.

To avoid spreading [[infectious diseases and parasites]] to a new nucleus, you should ensure that your colonies are healthy. This can be done with either a visual inspection or by sampling the bee hives for a laboratory test (for instance, every fourth year). [[Swarming ]] is a natural way for the bee colony to get rid of microbesdiseases and parasites. The swarms can be placed onto into a hive with new wax foundation once frames, so that the colony has can completely renewed its comb structure and diminished thus diminish the infection pressure.  '''Late summer/Fall''' <br />Keeping the [[Varroa |varroa]] mite level low in the colonies is one of the key factors in successful beekeeping.
