Swarming is getting into high gear. I have collected three swarms so far. I have had several calls from the public about swarms in trees. An inspection for swarm cells with a 7-10 day schedule will catch queen cells before they are capped.
If you see capped swarm cells in your hive, it has more than likely swarmed. Hives with two year old queens are more prone to swarm than hives with new queens.
A hive that has swarmed will usually not produce much excess honey.
The swarming season usually lasts until the nectar flow starts coming on strong..
