Every successful honey bee colony revolves around one crucial member: the queen. While worker bees perform most of the visible jobs around the hive, the queen plays the essential reproductive role that allows the colony to maintain its population and thrive.
However, queens do not remain equally productive forever. Age, poor mating, genetics, environmental stress and other factors can reduce a queen's performance. When this happens, requeening can help restore colony strength, improve temperament and introduce more desirable genetics.
For Australian beekeepers wondering when to replace a queen—or looking to buy queen bees in Australia—understanding the signs of queen decline and the requeening process is an important part of good hive management.
What Is a Queen Bee?
A healthy honey bee colony normally contains one queen, thousands of female worker bees and, depending on the season, a population of male drones.
The queen's primary role is reproduction. During favourable conditions, a productive queen can lay very large numbers of eggs, helping the colony build the workforce needed to collect nectar and pollen, raise brood, defend the hive and maintain its internal environment.
The queen also produces pheromones that influence colony organisation and behaviour.
Although queens can potentially live for several years, longevity shouldn't be confused with peak productivity. NSW beekeeping guidance notes that the commercially productive life of a queen is generally only one to two years, with her capacity to lay large numbers of worker eggs declining as she ages.
This is why experienced beekeepers assess the queen by colony performance rather than simply asking whether she is still alive.
What Does Requeening Mean?
Requeening is the process of replacing the existing queen of a colony with another queen.
Agriculture Victoria describes requeening as removing a colony's queen and replacing her with a queen of the desired strain. The practice can be used to replace an old queen or one with reduced egg-laying capacity, as well as to introduce desirable characteristics into a colony.
Rather than waiting until a queen disappears or fails completely, planned requeening gives beekeepers greater control over their colonies.
A beekeeper might requeen to:
- Replace an ageing or poorly performing queen.
- Improve brood production.
- Change undesirable hive temperament.
- Introduce selected genetics.
- Improve colony productivity.
- Establish a queen in a newly created split.
- Replace a missing or failed queen.
The appropriate reason and timing will depend on what is happening inside the individual colony.
6 Signs It May Be Time to Requeen Your Hive
1. The Brood Pattern Has Become Patchy
One of the best indicators of queen performance is the brood pattern.
A strong laying queen will almost generally produce a relatively consistent brood pattern when conditions are favourable. As a queen's laying performance deteriorates, beekeepers may notice increasingly scattered or patchy brood.
Empty cells among developing brood can occur for several reasons, so a patchy pattern doesn't automatically prove that the queen is failing. Disease and other colony problems should also be considered.
However, if other causes have been ruled out and the queen is laying inconsistently, replacement may help rebuild colony strength.
2. The Colony Is Underperforming
When several colonies are kept in the same apiary, differences in performance can become easier to identify.
If one colony remains noticeably weaker than neighbouring hives despite experiencing similar weather and forage conditions, queen quality or genetics may be contributing to the problem.
Agriculture Victoria notes that differences in honey production between colonies in the same apiary can sometimes result from differences in bee strain and queen quality.
Before requeening, investigate other explanations such as disease, pests, food shortages or environmental conditions. If these have been ruled out, replacing the queen can be a logical management option.
3. The Hive Has Become Excessively Aggressive
Temperament matters, particularly for hobby beekeepers keeping colonies near homes, neighbours, livestock or frequently used areas.
Some colonies are simply more defensive than others. Because worker bees inherit genetic characteristics from their queen and the drones with which she mated, introducing a queen selected for a calmer temperament can gradually change the characteristics of the colony.
The change won't happen overnight.
Existing workers remain in the colony until they reach the end of their natural lives. As new workers produced by the replacement queen progressively become the majority, the colony's temperament may change.
If you are dealing with a dangerously defensive colony, use appropriate protective equipment and consider obtaining assistance from an experienced beekeeper.
4. The Queen Is Ageing
A queen may live for years, but her reproductive performance can decline well before the end of her life.
For this reason, some commercial beekeepers replace queens routinely rather than waiting for obvious failure. Hobby beekeepers may keep queens longer and replace them according to performance.
Buzzbee notes that many commercial beekeepers replace queens annually to maintain young, productive queens, while hobbyists may replace them around every two years or when necessary.
The best approach is to monitor each colony. Age is useful information, but brood pattern, colony population, temperament and productivity provide a better overall picture.
5. The Colony Is Queenless
Sometimes requeening isn't optional—the colony has lost its queen.
A queen may disappear because of injury, beekeeper error, unsuccessful supersedure or other events. Queenless colonies can attempt to raise an emergency replacement if they have suitable young larvae available.
However, buying a mated queen can provide beekeepers with another option, particularly when establishing a replacement queen promptly is important.
Be careful when diagnosing queenlessness. Not seeing the queen during an inspection does not necessarily mean she isn't there. Look for eggs and young brood and carefully inspect the colony before introducing another queen.
6. You Are Creating a Hive Split
Splitting a strong colony is a popular way of increasing hive numbers.
Depending on how the split is performed, one part of the divided colony may be left without a queen. The bees may be allowed to raise their own queen, or the beekeeper can introduce a purchased mated queen.
Using a mated queen can reduce the period spent waiting for a virgin queen to emerge, mature, mate successfully and begin laying.
Why Requeen Instead of Letting Bees Replace Their Own Queen?
Honey bees are capable of replacing queens naturally.
Supersedure occurs when a colony raises a replacement for a deteriorating queen. Queenless colonies can also raise emergency queens when appropriate young larvae are available.
So why intervene?
One important advantage is greater control over genetics.
When purchasing a queen from a breeder, beekeepers can investigate characteristics such as temperament, productivity and other desirable traits. Agriculture Victoria recommends researching the characteristics of bees being purchased and considering traits including gentle temperament, disease resistance, low swarming tendency and honey production.
A purchased mated queen also removes some of the uncertainty associated with raising and mating a replacement queen locally.
When Is the Best Time to Requeen in Australia?
Timing varies considerably across Australia because beekeeping conditions differ between regions.
Climate, local flowering patterns, colony strength and queen availability all influence the decision.
Generally, requeening is easier when colonies are active and conditions support brood production. Queen availability can also become limited during periods of strong seasonal demand.
Buzzbee reports particularly high demand for queen bees around spring, when colonies are expanding rapidly. Planning ahead can therefore be valuable if you intend to requeen as part of your seasonal management program.
Emergency queen replacement, of course, may need to happen whenever a queen fails or disappears.
How to Introduce a New Queen
Introducing a queen isn't as simple as opening the hive and releasing her among the workers.
An unfamiliar queen can be rejected or killed.
A common method is introducing a mated queen inside a queen cage. The cage protects her while the colony becomes accustomed to her pheromones. Queen candy can act as a delayed-release mechanism as bees gradually eat through it.
Before introducing a replacement queen, the beekeeper must ensure the existing queen has been removed and check carefully for queen cells.
Buzzbee recommends allowing a queenless period after removing the old queen before introducing the replacement and generally favours a slower, cage-based release instead of immediately releasing an unfamiliar queen into the colony.
After introduction, follow-up inspections are important to confirm that the queen has been accepted and subsequently begins laying.
Buying Queen Bees in Australia: What Should You Look For?
If you're planning to buy queen bees in Australia, don't base your decision on availability alone.
Consider the queen's breeding background and whether her genetics suit your objectives. Depending on your apiary, you may prioritise traits such as:
- Calm temperament.
- Strong brood production.
- Honey-gathering performance.
- Suitability for local conditions.
- Reduced tendency toward undesirable behaviours.
- Overall colony vigour.
It is also important to understand interstate biosecurity requirements before ordering live bees.
For example, Agriculture Victoria states that bees—including queens—entering Victoria from another Australian state or territory require approval and a health certificate. Requirements differ between jurisdictions and can change, so always check the current rules applying to your location before ordering or transporting live bees.
Buy Queen Bees in Australia from Buzzbee
For beekeepers looking to buy queen bees in Australia, Buzzbee supplies queen bees for Australian apiaries, subject to seasonal availability and applicable biosecurity and delivery restrictions.
Buzzbee's queen bees are supplied in cages with attendant worker bees to care for the queen during transport. A queen purchased individually is intended for introduction into an existing colony or appropriate split—it cannot establish a new hive by herself.
If you're starting completely from scratch, you need a colony containing a queen and the worker population required to maintain the hive.
Buzzbee also provides practical educational resources covering queen introduction, identifying when a hive needs a new queen and other aspects of queen management.
Explore the available queen bees and plan ahead where possible, particularly before periods of strong spring demand.
A Better Queen Can Mean a Better Colony
Requeening is one of the most useful management tools available to Australian beekeepers.
A queen influences far more than egg production. Through her offspring, she can affect colony population, productivity and temperament. Replacing an ageing, poorly laying or unsuitable queen can therefore have effects across the entire colony.
The key is to make decisions based on careful hive inspection.
Watch the brood pattern. Compare colony strength. Investigate unusually low production. Pay attention to temperament. Rule out disease and other problems before assuming the queen is responsible.
When replacement is appropriate, selecting a healthy mated queen with suitable genetics and introducing her carefully can give the colony a valuable fresh start.
