Beekeepers inspect their colonies of honey bees regularly and, during each inspection, check for five things.
• That there is enough room for the queen to lay and give more room if needed by adding supers.
• That the colony has enough stores to last until the next inspection.
• That the queen is laying well, which includes checking for queen cells, which would suggest that the colony is preparing either swarm or replace the queen.
• We check that the colony is healthy.
