I've found that if you want the bees to do something,they will likely not do it. I assume you do not have drawn comb or else you could remove the whole box and replace with comb. Some things I have read here might work: Scrape the cappings on frames you want them to move honey from, put 2 frames of open brood above excluder in your honey super. I haven't tried either method. Another possibility that I have done is to remove that box of capped honey, extract it and replace on hive. J
