Installing a new queen is one of the most nerve-racking moments in beekeeping, and also one of the most important. Get it right and the colony requeens smoothly, brood appears within a week, and the hive carries on as if nothing happened. Get it wrong and the workers kill the new queen in her cage, leaving you queenless, scrambling for a replacement, and a week behind. The good news is that queen introduction is a well-understood process with a high success rate when you follow a few simple rules: make the colony queenless first, give the workers time to accept the new queen's pheromone, and resist the urge to check too early.
This guide covers the three situations where you need to install a queen, the most common cage types, step-by-step introduction using the candy-plug method, how to read acceptance and rejection signs, and what to do when things go wrong.
When do you need to install a queen?
Three situations, each slightly different.
New package installation. Every package of bees ships with a separately caged queen the workers have never met. She must be introduced through a slow-release process so the bees have time to accept her pheromone before she is free inside the hive. This is the most common introduction scenario for beginners. Choosing between packages and nucs covers the broader decision, but the queen-introduction step applies only to packages (a nuc's queen is already accepted).
Requeening an established colony. If your queen is old, poorly mated, a drone layer, or producing bees with bad temperament, you replace her with a new mated queen from a breeder. Requeening also resets the brood cycle, which pairs well with Varroa mite treatment timing since a brief brood break during requeening exposes more phoretic mites to treatment. This requires finding and removing the old queen first, then waiting 24 hours before introducing the new one. Understanding the queen's role in colony health and behavior explains why requeening is sometimes the single best management decision you can make.
Emergency queenlessness. A colony that lost its queen unexpectedly (swarming, beekeeper error, disease, failed supersedure) needs a new queen fast. If the colony has been queenless for more than two weeks, it may have laying workers (workers that lay unfertilized drone eggs), which makes introduction harder. The sooner you catch queenlessness and introduce a replacement, the better the odds.
What types of queen cages are used?
The cage keeps the queen safe while the colony acclimates to her scent. Three types are common.
Benton cage (three-hole wooden cage). The traditional design: a small wooden block with three screened compartments, a candy plug at one end, and a cork at the other. The queen rides in the center hole with a few attendant workers. This is the most widely used cage in North America and what most package and mail-order queens ship in.
California mini cage (JZ-BZ style). A small plastic cage with a candy tube at one end and a cap at the other. Compact, lightweight, and increasingly popular because it is cheaper to produce and ship. The introduction process is the same as the Benton cage.
Push-in cage. A flat screen cage (usually #8 hardware cloth bent into a box shape) that you press directly into drawn comb over a patch of emerging brood and capped honey. The queen is released under the cage and begins laying immediately while the workers interact with her through the mesh. After 2 to 3 days, you remove the cage. Push-in cages have higher acceptance rates than candy-plug cages in difficult requeening situations (angry colonies, laying-worker colonies, or late-season introductions).
How do you introduce a queen using the candy-plug method?
This is the standard method for packages and most requeening. The candy plug acts as a time-release mechanism: the workers chew through it over 2 to 5 days, gradually exposing themselves to the new queen's pheromone. By the time she is free, the colony has accepted her scent.
Step one: make the colony queenless. For a package, the colony is already queenless (the queen is in her cage, not free). For requeening, find the old queen, remove her, and wait 24 hours. This waiting period lets the old queen's pheromone dissipate so the workers are receptive to a new scent. Skipping the 24-hour wait is the most common cause of rejection in requeening.
Step two: inspect the queen cage. Check that the queen is alive and moving. Look at the candy plug end: if there is a cork covering the candy, remove the cork to expose the candy. If there is a cork on the non-candy end, leave it in place. You want the workers to chew through the candy, not escape through an open hole.
Step three: poke the candy. Use a small nail or toothpick to poke one or two holes through the candy plug. This gives the workers a head start on chewing through. Be careful not to push deep enough to reach the queen.
Step four: hang the cage between frames. Place the queen cage between the two center frames of the brood box, screen side facing down so the workers can feed the queen through the mesh, candy end facing up (so if the candy softens in warm weather it does not drip onto the queen and suffocate her). Many cages have a metal tab or strap you can bend over the top bar to hang the cage. Make sure the cage is secure and will not fall to the bottom board.
Step five: close up and walk away. This is the hardest part. Put the frames back gently, close the hive, and do not open it for at least 3 days. Every time you open the hive during the introduction period, you disrupt the pheromone acclimation process and increase the risk of rejection.
Step six: check on day 3 to 5. Open the hive and inspect the queen cage. Three outcomes are possible.
The queen is out and the cage is empty. This usually means acceptance. Look for the queen on the frames (she should be walking freely, attended by workers). Check for eggs in cells within the next few days. Eggs confirm she is laying and accepted.
The queen is still in the cage. Check whether the workers around the cage are calm (feeding her through the mesh, antennae touching) or aggressive (biting the cage, clustering tightly with abdomens raised). If calm, give her another 1 to 2 days. If the candy is almost chewed through, you can help by gently removing the remaining plug. If aggressive, do not release her (see rejection section below).
The queen is dead in the cage. She was rejected before release. Contact your supplier within 24 hours, as most breeders replace dead-on-arrival or rejected queens at no charge.
How do you read acceptance versus rejection?
Acceptance signs. Workers calmly touching the cage mesh with their antennae. Workers feeding the queen through the screen (you may see them pushing their tongues through). After release: the queen walking freely on the comb, a retinue of 8 to 12 workers facing her and grooming her, and within 2 to 3 days, single eggs standing upright in the bottom of cells.
Rejection signs. Workers biting the cage aggressively, clustering on the cage in a tight ball, vibrating or buzzing loudly. After release: the queen running frantically across the comb, workers chasing and balling her (surrounding her in a tight, hot cluster that can overheat and kill her). If you see balling, gently break up the cluster by smoking it lightly and place the queen back in a cage for another 24 to 48 hours before trying again.
What do you do if the queen is rejected?
First, find out why. The most common reasons for rejection are: the old queen's pheromone is still present (you did not wait 24 hours, or the old queen was not fully removed), the colony has already started raising emergency queen cells (destroy all queen cells before reintroducing), or the colony has laying workers (multiple eggs per cell, eggs on the cell walls rather than the center). Laying-worker colonies are the hardest to requeen because the workers' ovaries are active and they treat a new queen as a rival.
If the first introduction failed, try again with a push-in cage on a frame of emerging brood. The emerging young bees accept the new queen more readily than older workers. Give it 3 to 4 days under the push-in cage before removing it.
If the second attempt fails, combine the queenless colony with a queenright colony using the newspaper method, and re-split later once the combined colony is stable. Splitting and combining colonies strategically covers the technique.
What mistakes cause the most queen failures?
Not removing the old queen first. A colony with a laying queen will almost always reject a second queen. Find and remove the old queen before any introduction.
Checking too early. Opening the hive on day 1 or 2 disrupts the acclimation process. Wait at least 3 full days, ideally 5 to 7 for difficult requeening situations.
Leaving queen cells in the hive. If the colony has started raising its own emergency queens, destroy every queen cell before introducing the new queen. Otherwise the workers will favor their own queen cells and reject yours.
Direct-releasing a mail-order queen. Pulling the cork and dumping the queen directly onto the frames without the candy-plug acclimation period almost always results in rejection. The slow release exists for a reason.
Rough handling. Queens are fragile. Do not shake the cage, drop it, or leave it in direct sun. Handle it gently, keep it shaded and warm, and install it the same day you receive it if possible. Having your bees and equipment ready before the queen arrives prevents rushed installations.
What gear do you need for queen introduction?
Queen work is the closest, most precise hive work you will do. You are pulling frames, searching for a specific bee among thousands, handling a tiny cage, and doing it all while the colony is more alert than usual. At OZ Armour, we build gear for exactly this kind of careful, hands-on work. Our ventilated bee suits built for long, careful inspections keep you cool enough to take your time, and pairing them with beekeeping gloves thin enough to feel a queen cage and a beekeeping veil with a clear view of every frame gives you the dexterity and visibility queen work demands. For a quick day-3 check, a beekeeping jacket you can pull on in a minute and bee trousers that seal tight at the ankle cover the job. Families who learn queen work together can outfit younger helpers in a kids' bee suit built for close hive visits. A smoker and hive tool round out the kit, though use smoke sparingly during queen introductions, since heavy smoke can agitate the colony and increase rejection risk.
Getting a queen accepted is patience work. Follow the process, resist the urge to peek, and let the bees do what bees do. For a broader seasonal picture, a 12-step guide to becoming a beekeeper covers every stage from first hive to first harvest, and choosing the right bee breed for your climate sets the genetics up before the queen arrives.
