Glossary
The process of dividing a single strong colony into two or more colonies to increase the number of hives, prevent swarming, or produce nucleus colonies for sale. Splitting is one of the most important colony management techniques for expanding an apiary without purchasing new bees.
The simplest split method: divide the colony roughly in half, ensuring each half has frames of eggs, open brood, capped brood, honey, and pollen. One half keeps the original queen; the other raises a new queen from existing eggs or young larvae. Walk away and check in 4 weeks.
The queenless half will select young larvae (under 3 days old) and construct emergency queen cells. A new queen will emerge in approximately 16 days, mate within 1-2 weeks, and begin laying. The split may not be fully productive for 6-8 weeks due to the brood cycle gap.
For faster results, provide the queenless split with a purchased mated queen, a ripe queen cell, or a frame of eggs from a colony with desirable genetics. A mated queen begins laying immediately, eliminating the 4-6 week gap of a walk-away split and dramatically improving the split's chances of success.
Timing is critical. The best time to split is during spring buildup, approximately 4-6 weeks before the main nectar flow, when colony populations are expanding rapidly and the original colony has enough bees to spare without compromising its own nectar flow performance.
Spring, when colonies are growing rapidly and before swarming season. In Florida, February through April is ideal. The parent colony should have at least 8-10 frames of bees. Splitting too early (weak parent) or too late (missed nectar flow) reduces the benefit.
Yes. Splitting removes bees and brood, reducing congestion, which is the primary swarm trigger. A well-timed split in spring, when swarm preparations are most common, can eliminate the swarming impulse for the season.
The parent colony should have at least 8-10 frames of bees (occupying most of two deep boxes) with a solid brood pattern before splitting. Splitting a weak colony creates two weak colonies, both of which may fail. Stronger is always better.
