Re: Best use of Comb
The key to getting bees above the excluder is to move a frame or two of brood above the excluder. Nurse bees will folow to attend to the brood. The nurse bees and emerging bees will stay above the excluder and the brood frames can be returned below the excluder. If you don't put brood above the excluder, there is a big danger of backfilling the brood nest with nectar and swarming.
Apply a thin coat of bees wax to plastic foundation, using a foam paint brush and bees will much happier with it. I also plan to try the 3 or 4 inch foam paint rollers to apply wax to plastic foundation.
If you always do what you always did, you'll always get what you always got!
