Kind of what I noticed to. They first plug the brood frames to avoid pulling fresh foundation. Once they are out of room, still getting fed with no where to put it, then mine started drawing. I also do like a previous poster....once super is full, pull, freeze, put on new foundation.
- Didn't notice any swarm cells when they first started plugging out....but I kept an eye on it.
Took a month of getting nothing before they started pulling the super, now they are clearing up the brood box and pushing the sugar higher.
