What Is Robbing in Beekeeping
Robbing in beekeeping refers to the act of bees stealing honey from another colony.
This occurs when stronger colonies take honey from weaker ones as a reallocation of resources.
Robbing can be triggered by natural vulnerabilities or lack of foraging opportunities.
It is a stressful situation for the targeted hive and can lead to the spread of diseases and parasites.
Signs of robbing include a flurry of activity around the hive, with bees grappling and attempting to sting each other.
To prevent robbing, it is important to keep colonies strong, use reduced entrances, and implement robbing screens.
Cleaning up spilled syrup and broken comb, as well as avoiding common feeding near hives, can also help prevent robbing.
It is crucial to address robbing swiftly as it can result in colony loss.
Robbing is more likely to occur in late summer and fall when certain conditions are present.
Conducting post-mortem examinations on beehives can help determine the cause of mortality and improve future management decisions.
Did You Know?
1. In beekeeping, “robbing” refers to the act of honeybees stealing honey from another hive. It is considered a negative behavior and can lead to conflicts between bee colonies.
2. Bees identify potential targets for robbing by recognizing specific scents and pheromones emitted by weaker hives. They exploit these vulnerabilities to raid another colony’s resources.
3. The robber bees often attack the guards of the weaker hive in order to gain access to the honey. They use their sharp mandibles to overpower and disable the defenders, allowing them to enter the hive.
4. To prevent robbing, beekeepers may use various techniques such as minimizing scent markers, ensuring strong colony entrances, and reducing swarming behavior, which can attract robbing bees.
5. Robbing behavior can have serious implications for the overall health and productivity of a bee colony. It can lead to the spread of diseases, stress, and even the complete collapse of weaker hives if not addressed in a timely manner.
Understanding Robbing In Beekeeping
Robbing in beekeeping is a natural phenomenon where bees from one colony steal honey from another colony. This behavior involves a reallocation of resources, with stronger hives seizing honey from weaker ones. Robbing usually occurs when bees face natural vulnerability or a lack of foraging opportunities.
The main reason behind robbing is competition for resources. Bees, driven by their instinct to gather as much honey as possible, may resort to stealing from other colonies if they are unable to find enough food sources in their surroundings. This behavior becomes more prevalent during times of nectar dearth or when normal foraging conditions become challenging due to factors such as extreme weather, changes in habitat, or human interference.
To summarize:
- Robbing in beekeeping refers to bees stealing honey from other colonies.
- Stronger hives take honey from weaker ones.
- Robbing occurs when bees face vulnerability or a lack of foraging opportunities.
- Competition for resources is the main reason behind robbing.
- Robbing is more likely during nectar dearth or challenging foraging conditions.
- Factors such as extreme weather, habitat changes, or human interference can contribute to robbing.

Causes And Consequences Of Robbing In Beekeeping
The act of robbing in beekeeping can have several negative consequences. Firstly, it increases stress levels within the colonies involved. The colonies being robbed experience a heightened sense of vulnerability and may struggle to defend their honey stores, leading to increased aggression and potential harm to the bees involved.
Robbing also acts as a vector for the spread of diseases and parasites among bee colonies. Robbed colonies may inadvertently bring back diseases and parasites from the targeted hive, introducing them to their own colony. This exchange of pathogens poses a substantial threat to the overall health of the colonies involved and can contribute to the decline of their populations.
In particular, the spreading of Varroa destructor mites and various bee diseases is closely linked to robbing. Varroa mites, which are known to weaken and destroy bee colonies, can easily hitch a ride on robbing bees and infest new hives. Additionally, diseases such as American foulbrood and European foulbrood can rapidly spread when infected bees invade other hives during the robbing process.

Identifying And Managing Robbing In Beekeeping
Identifying robbing in beekeeping involves observing specific behaviors and signs exhibited by the bees. A telltale sign of robbing is a flurry of activity in front of and around the hive, with bees grappling and attempting to sting each other. However, it’s important to note that this behavior can sometimes be mistakenly attributed to other activities, such as dead bees being carried out of the hive by undertaker bees.
To differentiate between robbing and other behaviors, beekeepers should also look for large, ragged-edge crumbs of cappings torn away during the honey theft. This destructive behavior is a key indicator of robbing. Additionally, timing can be another clue. Robbing raids typically occur until dark and start again at first light, whereas orientation flights, which are less aggressive and playful, usually take place in the afternoon and last for only a short period.
Managing robbing in beekeeping involves taking proactive measures to prevent its occurrence or minimize its impact. One effective strategy is to keep colonies strong. This involves regularly checking the strength of colonies, ensuring they have enough food stores, and addressing any issues that may make them vulnerable to robbing, such as a weak queen or high Varroa mite loads.
Using reduced entrances and entrance reducers can also help deter robbing. These mechanisms restrict the entrance size, making it easier for defending bees to protect their hive from intruders. Robbing screens are another useful tool. These screens create a physical barrier that allows bees from the colony being robbed to exit freely while preventing invading bees from entering.
Furthermore, minimizing the time the hive is open during inspections and promptly cleaning up spilled syrup or broken comb can reduce the likelihood of robbing. Avoiding common-feeding near hives is also recommended, as it can attract bees from neighboring colonies and trigger robbing behavior.
Preventing Robbing In Beekeeping Through Effective Practices
Preventing robbing in beekeeping requires several effective practices. One useful method is keeping the hive wet during inspections. Spraying water on the hive can create an environment that discourages robbing bees, as they prefer dry conditions for their activities. Simulating rain by using a lawn sprinkler near the apiary can yield similar results.
Moving the victim colony to another location can also help prevent robbing. This disruption to the bees’ familiar environment may disorient the robbing bees and discourage further attacks. However, it’s important to note that this method should only be used with caution, as it may cause additional stress to the colony being moved.
Installing robber screens and entrance reducers is another valuable preventive measure. Robber screens allow bees from the targeted colony to exit while deterring intruders. Entrance reducers restrict the hive entrance, making it easier for defending bees to protect their colony.
- Keep the hive wet during inspections
- Move the victim colony to another location
- Install robber screens and entrance reducers
“Overall, these practices can serve as effective tools in reducing the risk of robbing in beekeeping and maintaining the stability of bee colonies.”
Examining Robbing As A Factor In Hive Mortality
While robbing can be destructive to weak colonies, it typically does not act as the primary cause of colony mortality. Instead, other factors such as high Varroa mite loads or issues with the queen often weaken a colony, making it vulnerable to robbing.
When encountering a dead colony, it is possible to determine whether it died with honey stores and was subsequently robbed out by examining the remnants. If the honey stores are depleted and there are signs of robbing, it becomes evident that robbing played a role in the colony’s demise.
Conducting post-mortem examinations on beehives is vital for understanding the causes of colony mortality and improving future management decisions. By analyzing various factors like disease prevalence, Varroa mite levels, and signs of robbing, beekeepers can gain insights into the health and stability of their colonies. This information can then guide them in implementing appropriate measures to prevent robbing and ensure the long-term survival of their beekeeping operations.

Frequently Asked Questions
What does robbing look like in a beehive?
Robbing in a beehive resembles a chaotic battle at the entrance. As you observe, bees engage in fierce confrontations, grappling in pairs or triads, rolling around in disarray, and attempting to sting one another. These intense interactions signify the presence of robbing, with bees from foreign colonies invading to steal resources.
How do you stop robbing bees?
To deter robbing bees, one effective method is to create a physical barrier by placing a wide piece of metal or plastic against the hive’s entrance. This obstructs the entrance and makes it less conspicuous to potential invaders, while still allowing the resident bees to enter and exit freely underneath. Another approach is to implement a robbing screen, which offers an alternative entrance for your bees. This screen acts as a secondary door, allowing them to come and go while simultaneously safeguarding the main entrance from unwanted intruders.
What is a robbing screen for honey bees?
A robbing screen for honey bees is a clever device designed to regulate the entrance of bees into a hive and prevent unwanted intruders. By creating a barrier at the hive entrance, it effectively obstructs robbers from gaining access. Instead, resident bees are able to leave the hive through alternate routes by crawling up the hive front and utilizing slots on the screen’s top. This ingenious method ensures that only authorized bees can enter the hive, while keeping potential robbers out and maintaining a secure environment for the resident colony.
What is silent robbing bees?
Silent robbing bees are a fascinating phenomenon observed in bee colonies, where they differ from traditional robbers through their unique behavior. Unlike regular robbers who typically hover around the entrance before attempting to enter, silent robbers seamlessly infiltrate the robbed hive without any indication of hostility. This distinctive behavior implies a striking similarity in scent between the two colonies, potentially permitting one colony to grant entrance to the other without confrontation. The intriguing nature of silent robbing bees lies in their ability to bypass the usual front-line defense mechanisms, prompting further exploration into the intricate dynamics of hive scent recognition and communication among bees.
