When I checked four of my hives today, I found several swarm cells in each. Between now and the end of June is a crucial time for destroying swarm cells. Every ten to 12 days, I will go through my entire hive, one frame at a time, looking for swarm cells or the beginning of queen cells. Remember, these cells will have the cell opening pointing downward. When capped, these cells look similar to a small peanut hanging downward off the frame. Most of the time, queen cells are at the bottom of frames however, they can also be found at the top or in the middle of a frame. Doing regular hive checks through the month of June is EXTREMELY IMPORTANT!!
