Prevention focuses on reducing entrances, using robbing screens, feeding internally (not at the entrance), avoiding spills, and maintaining strong, healthy colonies to defend against attacks.
Bee robbing is when one colony of honey bees steals honey or sugar syrup from another hive. It usually happens during a nectar dearth, when natural food sources are scarce and strong colonies look for weaker ones to exploit. Left unchecked, robbing can destroy a weak hive in hours.

What Is Robbing In Beekeeping?
Robbing happens when forager bees from a strong colony invade a weaker hive to steal honey or sugar syrup. Foraging is the primary activity of honey bees to gather nectar and honey from flowers and other sources, but sometimes this foraging behavior shifts to robbing when resources are scarce. Looting is the best analogy of robbing behavior in a hive.
In honey bees (Apis mellifera), bees robbing typically occurs when:
There is a nectar dearth
A colony is weak because they are unable to defend themselves from the onslaught of invading bees and have fewer guard bees. Weak colonies are particularly prone to being robbed because they have fewer guard bees to defend against invaders.
Equipment has cracks or exposed syrup
Feeding triggers scent attraction
The robber honeybee is not trying to kill the queen or steal brood. They are only after the honey, nectar or sugar water.
Robbing bees are typically older worker bees that would otherwise be foragers. Once a forager finds an easy target, she returns to her hive and recruits others. What starts as a few scouts can quickly become a full-blown robbing frenzy.
Quick Signs Your Hive Is Being Robbed
1. Fighting at the Entrance
Increased activity at the front of the hive, such as fighting or bees trying to force their way in, is a key area to observe for signs of robbing. Bees wrestling, tumbling, or locking legs on the landing board.
2. Bees Dragging Other Bees Out
Guard bees remove dead or dying intruders. You'll see dead or dying bees on the ground around your hive. The casualties of war.
3. Wax Cappings on the Landing Board
Small white flakes from uncapped honey cells.
4. Hovering Bees Around Cracks
Robbers searching for alternative entry points. They can often be seen hovering around the back of the hive, while your own bees will not be searching for a new entrance. Pay close attention to any bees that appear to be trying to enter the hive in unusual locations like any gaps between boxes, under the bottom board or 2nd entrance. Robbers will try to get inside another hive any way possible and will investigate each crack and crevice on the hive.
5. Loud, High-Pitched Buzzing
More frantic and chaotic than normal flight traffic.
Even on the busiest honey flow day, robbing looks different. It feels aggressive. If you’re unsure whether you’re seeing robbing or orientation flights, look for fighting. Orientation flights do not involve combat.
How Long Will Robbing Last
So, how long will robbing behavior last? Robbing can occur during times of nectar dearth, when colonies are weak, or under certain environmental conditions.
Robbing could go on for days or hours. The robbing activity would only stop if the defending colony of bees drive them off or if they depleted all the honey in their target hive. It may take several days for the robbing activity to fully stop once it has started.
Robbing can increase in intensity in a short amount of time as robber bees return to their nest and recruit more robbers from their own hive to join in the behavior. This is because the robbing bees know there is an opportunity and they want to capitalize on the opportunity until they can’t anymore.
Remember, robbing is a crime and animals don’t have an understanding of social norms like right and wrong so even with best efforts at educating your own colonies about stealing from others, some will still break rank and try to steal from neighboring hives (This is a joke). You can’t stop your bees from robbing others.
You can only prevent your hives from being robbed.
Why Does Robbing Start?
Robbing doesn’t usually begin randomly. It’s almost always triggered by opportunity.
Common Causes of Robbing:
Nectar dearth (late summer and fall is most common) -Strong colonies with excess foragers are constantly looking for resources.
Weak or queenless colonies - Making it as an easy target
High varroa loads – unmanaged varroa mite infestations and treatments can weaken colonies and make them easy targets
Entrance feeders dripping syrup
Spilled sugar water - If they detect exposed sugar, they will capitalize on it.
Large entrances on small colonies
Equipment gaps, or rotten pine boxes - the robber bees have the opportunity to easily access a hive through poorly maintained equipment
Not all hives are candidates to be robbed, but beehives that already have issues are most likely to be robbed out. It really all boils down to the bees having an opportunity to rob out another one. It’s like the big bully on the playground taking the snacks from the kid who can’t stand up for themself. Not the best analogy, but you get it.
Since the dawn of agriculture, wherever there has been a hoard of vital resources, there have been those who attempt to take such resources by force. But long before any man or mouse had ever raided any granary, the humble honey bee had already perfected the art of the steal.
While it may be apparent when robbing is done by another species, robbing honey bees seldom wear ski masks and both teams are usually wearing the same jerseys so it’s not always obvious what is going on. I mean, how can you actually tell the difference between your own bees and the other bees invading your hive?
Robbing happens more in the late summer and fall when several conditions align, such as nectar dearth after a main flow, large colony populations with a high proportion of foragers, temperature suitable for flight activity.
This combined with an increase of weak colonies due to summer stress, varroa mites, or pests like small hive beetles (which can be managed with reusable small hive beetle traps or a baitable small hive beetle trap) creates a great opportunity for colonies to rob and be robbed.
Robbing can be a major problem in the southern part of the United States, especially during summer or when other major nectar dearths occur. The robbing problem is intensifying as more backyard beekeepers and hobbyists are getting into beekeeping, resulting in hives being in much closer proximity to one another.
There are many different methods and techniques that beekeepers can deploy to combat the robbing of their hives, some preventive and some reactionary. But robbing is one of those things that is going to happen from time to time, and the important thing is that beekeepers know what they are up against.
Robbing can be combatted in many ways, but it helps if you know which strategy would work best in your situation, including choosing the right beekeeping supplies and support services.
Can Robbing Kill A Hive?
Yes. Severe robbing can:
Kill bees and the queen - Bees that are killed by robbers will often leave a pile of dead bodies on the ground or near the entrance point of the hive.
Deplete all honey stores it can't sustain itself.
Overwhelm guard bees
Leave the colony too weak to survive - cause such irreparable danger that the colony is practically dead
In many cases, robbing is not the root cause — the colony was already weak. But robbing is often the final blow.
As I have said before, robbing is one of those things beekeepers hate to see but must do something about. Now you know how and when (if) you should act based on your observed bees activity and what you see. So, if a situation like this presents itself, its best to stay as cool and collected as possible while taking actions that will protect your bees and help the hive recover from this temporary robbery, and continuing to grow your knowledge through hands-on beekeeping classes and mentorship.
How To Stop Bees From Robbing Your Hive
When robbing starts, speed matters. Your goal is simple: Make the hive harder to enter.
However, the best approach is to take proactive measures to prevent robbing before it starts. By using hive management strategies like entrance reducers and robbing screens early, you can protect your hive’s health and resources.
It’s not necessary to divide the bees out, you just need to keep the robber bees from getting in. There are many ways to do this, but the important thing is you do something to help.
1. Reduce the Entrance (Fastest Solution)
The quickest option is to reduce the entrance to the hive to only big enough for 1 or 2 bees to come and go at once.
You can use:
A mouse guard
Sticks
A brick
Even pine straw
A smaller entrance makes it easier for guard bees to defend. Think of it like defending a castle gate. Smaller is stronger.
2. Close the Entrance Temporarily
Remember the kid that was a poor sport and when he (always a boy for some reason) was losing, he would pick up the ball and go home. It’s time for you to be that boy for the sake of your bees.
If robbing is intense, you can completely close the entrance for 1–2 hours. Closing off the hive entrance with grass or other materials can help deter robbing. If robbing is severe, moving the hive three miles away from the robbing location can effectively stop the robbing behavior.
Options include:
Blocking with grass , wood, stick or other materials - These reducers can double as a reducer and a moving screen and can be very helpful with robbing.
A wet towel to cover the hive entrance
This causes confusion and traffic jams, but it breaks the robbing cycle.
IMPORTANT: Do not block ventilation, especially in extreme heat. So don’t close off the screened bottom board and if you are in a place with those crazy summer temperature (I’m talking to you Texas), you might want to try and shade your hive or don’t even try this.
After robbing slows, reopen with a reduced entrance. Be aware, robber bees will probably be back later so be prepared for when they try again.
3. Install a Robbing Screen (Best Long-Term Solution)
A robbing screen is one of the most effective tools for preventing robbing. They are a type of plastic or mesh cover that attaches over the existing entrance of the hive which changes the direction of the bees entering and leaving their hive. They have an open mesh front that confuses any bees wanting to rob the hive because they can see inside the hive, but can’t easily figure out how to get there.
It can be installed year around, but they will interfere with other activities like feeding or cleaning out the hive. For this reason, they are typically put on before robbing season starts (during the hottest part of the summer).
It works by:
Blocking the direct entrance
Forcing resident bees to use a new exit path
Confusing robbers who rely on scent memory
Your bees quickly learn the new route. Robbers do not. Robbing screens are especially useful:
During nectar dearth
When feeding sugar syrup
During honey harvest
In high-density apiaries
They also help reduce drift and discourage mice, wasps and hornets. If robbing is a recurring issue in your area, installing a robbing screen before dearth season starts is one of the smartest preventative steps you can take.
How To Use Robbing Screens
The method of installation depends on the kind of screen you choose. While there are a few types of robbing screens, most of your choice lies in what they are made of and how you put them on as they all function the same way.
If you are a traditionalist who likes the wooden look, you have many options to choose from. These will typically install with either nails or screws, although they can also be installed with bungee cords around the hive.
If you prefer the functionality and economy of polymers, the BeeSmart ultimate robbing screen is hard to beat. It features push pin installation which many may prefer to the options which nail or screw into your hive.
4. Stop Using Entrance Feeders During Dearth
During a nectar dearth, limit hive inspections to reduce the risk of robbing, and be cautious when feeding sugar syrup.
Entrance feeders are convenient but they are robbing magnets. Why?
They place sugar syrup directly at the hive entrance, where scent spreads easily.
Instead, switch to more defensible options like a 10 frame top feeder or other internal feeders:
Top feeders, bucket feeders, or other enclosed systems like a 1–2 gallon bucket feeder
Internal feeders, such as a medium frame division feeder with ladder
Frame feeders
These place syrup inside the hive, making it easier to defend. It may take several days to break the robbing cycle after the initial robbing activity is stopped. This is because the robber bees will just keep coming back to try and start robbing again.
In this colony in the picture, it was suffering from a robbing situation where the entrance feeder was attracting robber bees. We removed the feeder and changed it to an internal feeder. We reduced the entrance down to about the size of 2 bees and piled pine straw on the front.
The pine straw on the front was loose enough to allow bees to get out, but tight enough to make it harder for robber bees to get in. Immediately after doing this, the robber bees starting looking at other places on the hive to get in.
The pine straw was left on there for a couple days until all robbing behavior was gone.
Feeders
Entrance feeders are easy and convenient to use but anything sweet at the front of the hive, where entrance feeders are typically placed, raises the risk of robbing.
Because they drip sugar water right near the entrance at the front of the hive, it can be difficult for guard bees to defend.
If using entrance feeders during a dearth, move the actual entrance to the hive to the opposite side of the feeder so that it would be more difficult for robbing bees to access the feeder.
Top Feeders
Top or Inside feeders are generally a good idea during a dearth. They place the sugar water in roughly the same location the honey would be otherwise, allowing the bees to guard the hive in a similar manner.
The top feeders make it easier for the colony to defend it. Robbing bees will have to travel all the way through the entrance and up into the hive to rob out the feeder. Because of this, if you are feeding during a dearth, these are a good option compared to open feeding and entrance feeding.
Frame Feeders
Frame feeders are a great option for feeding during the summer dearth. They are an internal feeder that takes the place of 1 or 2 frames. The feeders are easier to defend against robbers compared to entrance or Boardman feeders.
They can also hold more than many other feeders so you would have to refill them less often.
The more you feed the colony in the summer, the more opportunities there are to spill sugar water.
When the time comes to pull supers, having the right honey harvesting and extraction tools can help you work quickly and cleanly, reducing the chaos that can trigger robbing.
5. Avoid Open Feeding
Open feeding is where you place a feeder 200-300ft away from any of your hives to allow all the bees to feed. When feeding your hives using an open feeder, you are creating a robbing event, but it is at the feeder instead of at a colony, especially if you are using large-capacity bucket feeders with components like a tint plug for bucket feeders.
Open feeding creates a frenzy. When the syrup runs out, those bees look for the next sugar source — often your weakest colony. Using well-coated plastic foundation with double beeswax can also help colonies draw strong comb quickly so they can store and defend their own resources.
It may seem helpful, but it often makes robbing worse. Focus instead on smart feeding and efficient honey handling with tools like no-leak honey gates and hive tools that keep things tidy around the apiary.
6. Use Water to Break a Frenzy (Temporary)
A fine mist of water around the hive can disrupt robbing behavior. It makes flying difficult and forces robber bees to retreat.
This is not a long-term fix — but it can buy you time.
Avoid Using Any Supplements
Bees will naturally drink sugar water, but there are times when you want to give them something extra to make them drink it faster or for some health reasons.
Feeding supplements like Honey B Healthy, Pro Health, Hive Alive and other products, or highly attractive ready-to-use feeds like Pro Sweet syrup, will make the sugar water more enticing to robber bees.
If feeding during a dearth, please don’t add those supplements because it could possibly cause a problem. Wait until the summer dearth is over before using those products.
Feeding During The Summer Dearth
Let’s be honest, there isn’t a perfect time to feed your bees and during a summer dearth is one of those. We don’t like to have to feed our bees, but sometimes it’s necessary, even during the worst time of the year. Good wax foundation, frames, and assembly tools also make it easier for colonies to store and protect those hard-earned food reserves.
To reduce risk, and to keep bees working productively on well-built comb in quality frames and foundation equipment or starter strips and foundationless frames:
Feed internally -the type of feeder you use can make a difference, so let’s take a look at your options.
Avoid spilling syrup - always cover exposed sugar syrup and use feeders that minimize spillage to avoid attracting robbing bees.
Do not add strong-smelling supplements during dearth
Reduce entrances before feeding
If feeding stimulates robbing repeatedly, reassess colony strength. A weak hive may need additional support or relocation.
The Best Defense: A Strong Colony
One of the best defenses against robbing behavior is simply having a strong colony. When your hive is packed with a healthy number of bees, especially guard bees, it becomes much harder for robber bees to break through the entrance and steal honey.
Beekeepers should focus on keeping their colonies robust by ensuring there’s plenty of food, a healthy queen, and a good environment for growth. Regularly check the number of bees in the hive and watch for any signs of weakness. If you notice your colony is struggling, take measures to boost its strength—like supplementing food or addressing health issues before robbing becomes a problem. A strong colony means more bees at the hive entrance, ready to defend their home and keep robbing at bay.
Regularly check your brood pattern and population on your deep Langstroth frames:
Brood coverage
Varroa levels – consider using drone brood frames for mite management as part of an integrated pest control strategy
Food stores
If the queen is weak, old, or not laying enough eggs, the colony can quickly become vulnerable. A failing queen or high mite load can silently weaken a colony, making it a target. Healthy bees defend themselves.
Finishing Up
Bee robbing can escalate quickly, but it’s manageable when caught early.
- Watch for the signs.
- Reduce entrances proactively.
- Avoid feeding mistakes.
- Install preventative measures before dearth hits.
Robbing is one of those hard lessons in beekeeping that teaches vigilance. The key isn’t panic, it’s preparation. If you protect your entrances and maintain strong colonies with well-designed equipment like screened bottom boards for 10-frame hives, you’ll dramatically reduce the chances of losing a hive to robbing.
