When to Requeen a Hive

Requeening is replacing an old or failing queen with a new one. It’s one of the most important management tasks you’ll do, but also one that confuses beginners the most. This guide covers when to do it and why.

Signs Requeening Is Necessary

The most common reason to requeen is age. A queen typically lasts 2–3 years, but her productivity drops sharply after year two. You’ll notice a decline in brood patterns— fewer eggs laid, more empty cells in the brood area, or spotty patterns instead of solid coverage. When you install a new queen, mark her with a small dot of queen-marking paint on her thorax (the middle section of her body) so you can identify her quickly during inspections and track her age. Queen-marking pens are available from beekeeping suppliers and are safe for the queen when used correctly; practice on a drone first if you’re nervous about handling her.

A failing queen may also lay drone (male) eggs in worker cells, a sign her sperm supply is running low. If you open the hive and see multiple drones emerging from worker-sized cells, requeening is worth considering.

Sometimes a queen simply goes missing or dies. You’ll see no eggs or fresh brood for 2–3 weeks, and the colony may become agitated or start laying worker eggs (workers laying unfertilized eggs that become drones). This is called a “laying worker” situation and is harder to fix than simply requeening a queenless hive.

A queen can also be injured during handling or killed by the colony itself if something goes wrong. If you accidentally crush her or she’s found dead on the bottom board, you need a replacement.

Finally, some queens are just poor layers from the start—a genetic issue or damage during mating. If a first-year queen shows weak brood patterns with no obvious disease, requeening may be your best move.

Best Season to Requeen

Note: The timing below applies to temperate Northern Hemisphere climates. If you are in the Southern Hemisphere, a Mediterranean climate, or a region with an unusual seasonal pattern, adjust these windows to match your local spring buildup and pre-winter contraction periods.

Spring and early summer are ideal. The colony is building up, there’s plenty of forage, and worker bees are abundant to care for a new queen. A new queen introduced in spring will have time to establish herself and build a strong laying pattern before the critical honey flow.

Avoid requeening in late fall or winter. Colonies are contracting, there’s little forage, and a new queen may not lay enough to sustain the hive through the cold months. If your queen fails late in the season, you’re usually better off letting the colony combine with another hive (if you have one) or accepting that you’ll likely lose it.

Mid-to-late summer is workable but less ideal. The colony may be preparing for winter already, and a new queen won’t have as long to build her population before the season ends. That said, if your queen fails in midsummer, requeening is still worth attempting.

Never requeen during a nectar flow if you can avoid it. The colony is focused on foraging, and introducing a new queen during this intense period can cause rejection or poor acceptance. Wait until the flow slows or ends, even if it means waiting a few weeks.

Requeening After a Failed Queen

If your queen dies or disappears, you have a narrow window to act. The colony will begin raising laying workers within 2–3 weeks if left queenless, and once that happens, fixing the problem becomes much harder.

Your first option is to order a new queen from a reputable breeder. Most breeders ship queens in small cages with attendant bees and food. This takes 1–2 weeks, so order immediately if you discover a failed queen. When the queen arrives, introduce her using the cage method: remove the cork from the candy-plug end of the cage, place the cage candy-end up between two frames, and let the colony release her over 2–3 days. The bees will eat through the sugar candy plug and free her gradually, giving time for the colony to accept her scent before she is released.

Your second option, if you have another hive, is to move a frame of open brood (eggs and young larvae) from a healthy hive into the queenless one. The queenless colony will often raise their own queen from those eggs—a process called “emergency requeening.” This is free but takes longer (3+ weeks) and the resulting queen may be lower quality than a purchased one.

A third option is to combine the queenless hive with another colony. Use the newspaper method: place a sheet of newspaper between the two hive bodies, and the bees will gradually chew through it and merge. This works well if you have a spare hive or want to reduce your colony count.

Don’t leave a hive queenless for more than 3 weeks. Once laying workers become established, the hive is nearly impossible to save.

Requeening for Temperament

Some beekeepers requeen to improve colony temperament—bees that are calmer and less likely to sting. If a hive is consistently aggressive despite good health and adequate food, requeening is a reasonable solution.

Replace the old queen in late spring or early summer, and choose a new queen from a breeder known for calm stock. The new queen’s daughters will emerge over 3–4 weeks, and you’ll notice a shift in behavior as they make up more of the population.

This is not urgent like requeening a failed queen—it’s a choice you make based on your comfort level and management goals. Many beekeepers tolerate moderate defensiveness. If you’re new, give the colony a full season before deciding to requeen for temperament alone.
