I have a colony from a swarm I captured back in April. After they had been in the hive for a month or so, they went queenless, no idea why, maybe there wasn't a queen in the first place? Or I missed her when I captured the swarm? Anyway last month I bought a mated queen locally and introduced her. An inspection 3 weeks later showed no eggs, larva or brood. I assume the rejected her. In a last ditch effort I pulled a frame of eggs, larva and brood from my strongest hive and inserted it about a week ago. How long should I wait before I inspect or expect to see results?
