Is there something in them, or are they just queen cups and empty? Is there a good flow going on? If there's a good flow and plenty of honey on and plenty of bees in the hive, they can swarm almost any time of year. I have had a hard fall flow and have had 4 out of 24 swarm from my neglect. They always need some attention.
