A honeybee colony does not automatically welcome a new queen. Worker bees recognize their queen through her unique pheromone signature, and any unfamiliar queen introduced abruptly will likely be attacked and killed – a behavior beekeepers call “balling.” Successful queen introduction is therefore a carefully managed process that gives the colony time to recognize and accept the new queen before she is fully exposed. Whether you are requeening a failing hive or expanding your apiary, understanding the right techniques can make the difference between a thriving colony and a queenless collapse.

Why queen introduction requires such care
Every honeybee colony has a distinct colony odor, largely shaped by the queen’s pheromones. When a new queen is introduced, she smells foreign to the worker bees. According to Purdue University Extension, a new queen’s integration depends on the acceptance and acclimation of the workers, which is not always guaranteed – queens may be rejected, injured, or killed during the process, which can ultimately lead to colony collapse if not managed properly.
This is why beekeepers use cages and indirect introduction methods: they create a buffer period during which the workers gradually become familiar with the new queen’s scent through the cage mesh, without being able to harm her. The colony’s readiness, the timing of the introduction, and the method chosen all play critical roles in whether the queen is accepted.
Preparing the colony before introduction
Before any queen is introduced, the receiving colony must be properly prepared. Purdue Extension recommends removing the old or failing queen and confirming her absence, removing all existing queen cells to prevent the colony from raising its own replacement, and allowing the colony to remain queenless for at least 24 hours. This queenless period creates a sense of urgency in the colony, making workers more receptive to accepting a new queen.
Young bees accept new queens more readily than older forager bees. For this reason, introducing a queen into a freshly made split – where older bees have returned to the parent hive – significantly improves acceptance rates. Large, established colonies can be harder to requeen successfully.
It is also worth checking the health of the new queen before introduction. As Purdue University notes, a healthy queen should have an intact, elongated abdomen, undamaged wings, and strong, active movement. Queens that have experienced temperature stress during shipping may have reduced fertility and lower pheromone output, both of which make acceptance more difficult.
The queen mailing cage (Benton cage) method
The most widely used introduction method relies on the queen mailing cage, commonly known as the Benton cage or three-hole candy cage. This small wooden or plastic cage has a mesh screen on one side and a candy-filled tube at one end. The queen travels inside the cage with a few attendant worker bees who feed and groom her during transport.
To introduce her, Glenn Apiaries advises placing the cage in the middle of the brood nest, between two frames, with the candy end pointing upward and the mesh screen unobstructed. The hive bees will begin to chew through the candy plug from the outside while the queen remains safely enclosed. This process typically takes 2-4 days, during which pheromone exchange through the mesh gradually familiarizes the colony with the new queen’s scent.
Harvest Lane Honey cautions that the queen should never be released manually before the bees have fully eaten through the candy – premature release dramatically increases the risk of rejection and death. If workers are actively biting or clustering tightly around the cage after 4-5 days, it signals they have not yet accepted her, and more time is needed before any intervention.
Handling attendant bees in the cage
Queens shipped from breeders usually arrive with a few attendant worker bees in the cage. Some beekeepers remove these attendants before introduction, reasoning that unfamiliar bees from the supplier may trigger aggression. Harvest Lane Honey recommends leaving the attendants in place during introduction, as they help keep the queen fed and calm. However, if removing them is preferred, this should be done carefully in a closed room to avoid losing the queen.
The hair-roller cage method
The hair-roller cage is a cylindrical plastic cage with slotted openings, resembling a hair roller used in hairdressing – hence the name. It is primarily used in queen rearing to house virgin queens as they emerge from their cells, preventing them from fighting and killing each other before the beekeeper can use them. The slots in the cage allow nurse bees in the finishing unit to feed the virgin queens through the openings, while keeping the queens safely separated from one another.
For introduction purposes, a hair-roller cage containing a virgin or mated queen can be suspended between frames in the brood area. Worker bees interact with the queen through the slots, gradually building pheromone familiarity. A candy cap is included to allow a timed release. According to HonestBee, the cage effectively suspends competition within the hive and gives the beekeeper total control over the timing of the queen’s release, making it a useful tool for both commercial breeders and researchers working with genetically valuable queens.
The push-in cage method
The push-in cage is considered by many experienced beekeepers to be the most reliable queen introduction method, particularly for instrumentally inseminated queens or difficult colonies. Unlike candy-plug cages, the push-in cage allows the queen to begin laying eggs before she is released – and this makes a significant difference to acceptance.
PerfectBee explains that queens actively laying eggs have higher pheromone levels and are more readily welcomed by the receiving colony. The cage is a rectangular piece of 8-mesh hardware cloth (or a purchased plastic version) that is pressed directly into a brood comb, enclosing the queen underneath it along with a patch of emerging brood and a small amount of open nectar.
Glenn Apiaries’ instructions specify that the cage should be pushed about a quarter inch into the comb and that no adult bees should be trapped underneath – only the queen herself. As capped brood cells beneath the cage begin to hatch, the emerging nurse bees accept the queen immediately and begin tending to her. After 3-5 days, once the queen has begun laying and bees on the outside of the cage show no aggression, the cage is simply lifted out and the queen walks freely into the colony.
Purdue Extension notes that plastic push-in cages are preferable to wire mesh versions because bees are less likely to chew around the edges and gain unwanted access to the queen before she is established.
Signs of acceptance and what to watch for
After releasing the queen – whether through candy dissolution or by removing the push-in cage – the colony needs time to settle. Purdue University Extension advises checking the colony 5-7 days after the queen’s release for clear signs of acceptance: the presence of freshly laid eggs and young larvae in a consistent, tight brood pattern with few empty cells. A well-accepted queen will show evidence of regular, organized laying within this window.
Signs of rejection include an aggressive colony clustering around the new queen, the queen found dead, or an absence of eggs after more than a week. Buzzbee International also highlights that forcing a rapid release – bypassing the gradual introduction period – frequently results in the balling and killing of the new queen. The slow-release approach, whether through candy or a timed push-in cage removal, is always the safer path.
The three most common reasons a queen introduction fails, according to Purdue Extension, are: the colony was not actually queenless at the time of introduction; the colony had been queenless longer than the beekeeper realized and laying workers had developed; or queen cells were still present in the hive at the time of introduction. Thoroughly checking for and removing all queen cells before placing the new queen in any type of cage is essential.
Choosing the right method for your situation
No single method guarantees success in every situation, but matching the technique to the colony’s circumstances improves your odds significantly.
The Benton mailing cage is the standard choice for most requeening situations – simple, widely available, and effective for calm, recently queenless colonies. The hair-roller cage suits virgin queens or situations where you need to manage multiple queens during rearing without them attacking each other. The push-in cage is the most thorough method and is recommended for aggressive colonies, instrumentally inseminated queens, or any situation where a high success rate is non-negotiable.
If a colony is particularly aggressive or has been queenless for a long time – long enough to develop laying workers – standard cage introductions may not be sufficient. In such cases, expert beekeepers suggest making a small split with young bees, allowing foragers to leave, and introducing the queen into the resulting nuc before combining it back with the main colony later.
Regardless of the method, one rule applies universally: avoid disturbing the hive unnecessarily during the first two weeks after a successful introduction. The queen needs time to establish her brood nest, and frequent inspections during this critical window raise the risk of disrupting that process.
What do you think? If you were requeening an aggressive colony for the first time, which introduction method would you choose and why? How might the timing of the introduction – early spring versus late summer – affect your approach to ensuring the colony accepts the new queen?
