Here, I will put an undrawn frame in an outside position at the beginning of summer as swarm control for overwintered hives I'm running for honey as singles. If I am slow checking on hives, giving them a frame to draw out can give me a couple more days before they try to swarm.
That surely not help. One frame do not save yoou from swarming.
When bees have swarming fever they do not draw foundations. They just wait to go.
Bees need weekly a box of new room when the hive enlarges. In best cases they need 2 new boxes.
There should be at least 2 new frames of foundation in each box of the brood chamber for there to be any affect to prevent swarming. In a ten frame hive there are usually 6-8 frames of brood with the 2 outer brood frames predominately drone comb. To prevent swarming a 3rd box should be added with frames barrowed from it to displace frames in the brood chamber. set up the two primary brood boxes thusly: CCFCCCCFCC*; then set up the new box this way: FFFCCCCFFF. A week to 10 days later, set the brood chamber up this way: CCFFCCFFCC followed by CCFFFFFFCC the next week. The third week it is necessary to add a 4th box in order to rotate new frames in. Then continue until all of the old frames in the brood box are changed out. This is also a good way to retire old brood comb frames.
* C=frames with comb, F=frames of foundation.
The queen will often go to the new frames and start laying in the cell imprints, forcing the worker bees to kick the building of foundation into high gear. Also this will expand the hive greatly as the equivalent of at least 3 boxes of brood in the later stages of the rotation/exchange of combs. Then use queen excluders to isolate the queen, remove that box as a split, taking 2 frames of new eggs for the old hive to make a new queen with. Super both hives at the time of the split.
You now have 2 strong hives with one a controlled swarm (walk away split). Of course if you don't want to wait for the hive to rear its own queen you can always use a purchased queen or one you reared yourself.
