Glossary
The practice of temporarily housing multiple mated queen bees in a specially managed colony or device until they are needed for requeening, nuc production, or sale. Queen banking allows beekeepers and queen breeders to maintain a supply of ready-to-use queens without maintaining individual colonies for each one.
Queens are housed individually in small cages within a specially prepared colony called a queen bank. The bank colony is typically made queenless (or uses a divided configuration) and is stocked heavily with young nurse bees that feed and attend to the caged queens through the cage screen.
Several factors determine the success of a queen bank: adequate nurse bee population (young bees that will feed the queens through their cages), proper temperature maintenance, adequate food stores, and limiting the banking duration. Queens can be successfully banked for days to a few weeks, though their quality may decline with extended banking.
Queen banking is particularly useful during spring splitting season when a beekeeper may need multiple queens within a short window. Rather than ordering queens to arrive on the exact day each split is made, the beekeeper can bank queens as they become available and deploy them as colonies are prepared.
Commercial queen breeders also bank queens after they are mated and before they are shipped to customers. This allows them to manage production schedules and ship queens in batches rather than individually as each queen completes her mating flights.
Queens can be successfully banked for 1 to 3 weeks under optimal conditions. Beyond three weeks, the queen's egg-laying ability may decline. For best results, use banked queens as soon as possible and ensure the bank colony has abundant young nurse bees.
Short-term banking (under 2 weeks) generally does not affect queen performance. Extended banking can reduce sperm viability and delay the queen's return to full laying after introduction. Freshly mated queens that begin laying immediately tend to be more readily accepted by new colonies.
Yes. Small-scale queen banking is feasible for any beekeeper who maintains multiple colonies. A strong, queenless nuc with ample young bees can bank 5 to 10 queens temporarily. This is useful during spring splits when you may receive queens before all your splits are ready.
