'''Spring'''
'''Mid summer'''
To avoid spreading infectious diseases 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 microbes. The swarms can be placed onto a new wax foundation once the colony has completely renewed its comb structure and diminished the infection pressure.
