Why Bees Can Become Aggressive – and How to Prevent It

Bees, commonly perceived as aggressive, actually exhibit aggression only when provoked or defending their hive. Their primary focus is not on attacking but rather on foraging for nectar and pollen. The level of aggression varies among species; for instance, honeybees generally show mild aggression, defending their hive only when necessary. Africanized honeybees (often dubbed “killer bees”), on the other hand, are more aggressive due to their heightened defensive nature. It’s crucial to distinguish between aggression and defense; bees usually sting only to protect their colony or themselves. Understanding bee behavior and maintaining a respectful distance from their hives can significantly reduce the likelihood of aggressive encounters.

In the below paragraphs, we will take a more detailed look at this topic.

While beekeeping is an exciting and rewarding activity, it can also be challenging at times. This is especially so when dealing with aggressive honey bees. Aggressive behavior in bees can be caused by several factors, such as genetics, environmental stressors, and disease. When beehives become aggressive, it poses a significant risk to beekeepers, nearby animals, and other people. When asking the question “are bees aggressive”, you need to understand the reasons behind this behavior and why it is crucial to maintaining a safe and healthy environment for the bees and those around them. In this article, I will explore the different factors that can contribute to beehives becoming aggressive and provide practical tips on how to manage and prevent such behavior.

Why Are My Bees Attacking Me?

Honeybees can become aggressive from time to time, but there is usually a reason they will start to fly at you when you approach the hive. You might find that bees tend to be more aggressive during late summer or early fall, for which there are very good reasons. It is because more of the conditions that are known to cause aggression exist at these times. Nevertheless, below are five reasons for aggressive honeybees:

1. Hunger

Just like humans, honeybees may become angry or aggressive if there is a lack of available food. If there is an interruption in the nectar flow, honey may become scarce and more precious. When beekeepers approach the hive, the bees might become defensive and aggressive as they try to protect what remains of their stores.

Bees may even resort to aggressive robbing of other hives if they fear they will not have enough to see them through the winter. Drones might also be ejected from the hive to ensure that the rest have enough food to last through winter and into the following spring.

Bees robbing from other hives can be aggressive, but so too can the bees from hives being targeted by the robber bees. If other bees are robbing your bees, you might notice them circling the hive aggressively as they try to defend their stores.

A sure sign that robbing is occurring is when you notice bees fighting with each other at the entrance of the hive. In such situations you will probably also notice dead bees on the ground in front of the hive entrance.

2. Missing Queen

One of the most common issues you may encounter is a missing queen. The queen bee is the heart of the colony and is responsible for laying eggs, which ensures the survival and growth of the colony. Her absence can create a great deal of stress and anxiety among the other bees, resulting in a variety of negative behaviors.

When a queen absconds or dies, the rest of the colony can become fearful and aggressive. This is because the queen’s pheromones are the primary means by which she communicates with the rest of the colony. Her pheromones help to regulate the behavior and activity of the other bees. Without her calming influence, they can become restless and agitated.

If a queen is missing, it is essential to take action quickly to prevent the colony from deteriorating. The first step is to identify whether the queen is truly missing or if she has simply stopped laying eggs due to age or other reasons. A queen can stop laying for a variety of reasons, including a lack of food or water, disease, or exposure to pesticides.

If you have determined that the queen is indeed missing, the next step is to raise a new queen. The colony will do this naturally if there are young larvae present, which can be transformed into queen cells. However, this process can take several weeks, during which time the colony may become increasingly agitated.

To expedite the process, you can introduce a new queen to the colony. This can be done by purchasing a new queen from a reputable breeder or by introducing a queen from another colony. Nonetheless, it is essential to introduce the queen slowly to prevent the bees from rejecting her.

3. Incorrect Smoker Use

As you probably know, beekeepers use a smoker to interrupt their bee’s alarm pheromone, which makes it easier for them to inspect their hive. However, some beekeepers, especially new or inexperienced ones, use either too much or too little smoke during the process. This can lead to agitated bees.

If you have chosen not to use a smoker, you are more likely to hear a loud hum upon opening up the hive. If this is the case, take this a warning sign that the bees are not happy. Once the alarm pheromone is released and proliferates in the hive, it acts as a warning to the bees of impending danger. Moreover, the louder the hum, the quicker this pheromone travels. So if you hear a loud hum, it is best to close the hive and back away. Consider using a smoker when inspecting your hive the next time, and learn how to use it correctly if you are new or inexperienced.

4. Bad Weather

One of the most critical aspects of managing a hive is being aware of the impact that weather can have on your bees. Bees are sensitive creatures that are highly attuned to changes in their environment and bad weather can have a significant impact on their mood and behavior.

Rainy weather is one of the most challenging conditions for bees to cope with. Although bees can fly in light rain they prefer not to, which means that they are unable to forage for food and water. Additionally, rain can make the hive damp and increase the risk of disease and pests. As a beekeeper, it is important to ensure that your hives are properly protected from the rain and that you do not disturb your bees during wet weather.

Wind is another factor that can impact the bees. Strong winds can make it difficult for bees to fly and forage, not to mention that it can also cause damage to the hive. When inspecting the hive during windy conditions, it is important to make sure that the hive is properly secured and that you approach it slowly and carefully to avoid startling the bees.

Dark clouds can also have an impact on the bees. They rely on the sun to navigate, so a lack of sunlight can disorient them and make them agitated. When inspecting the hive on cloudy days then, it is wise to use caution and move slowly to avoid disturbing the bees.

On the other hand, hot and humid weather can also affect the bees. When the weather is hot and humid, bees may have trouble regulating the temperature in their hive. It can also impact their ability to cure their honey properly. In such conditions, bees may also become more aggressive, so it is important to approach the hive slowly and carefully and avoid any sudden movements that might alarm them.

5. Predators

Predators can range from insects to mammals; all pose a serious threat to the hive and its occupants. It is essential then to take preventative measures to protect the hive and maintain a healthy bee colony.

Predators that commonly target beehives include rodents, skunks, raccoons, and wasps. These animals are attracted to the sweet scent of honey and pollen and will go to great lengths to access the hive. For example, rodents such as mice and rats will chew through the hive’s wooden exterior to gain access to the honeycomb. Skunks and raccoons on the other hand will use their strong claws to rip apart the hive’s protective coverings to reach the honey. Wasps will attack the hive directly, seeking out weak or vulnerable bees to kill and eat.

When predators target the hive, the bees become nervous and aggressive. This can result in a decrease in honey production and can even result in the death of the colony. Therefore, it is crucial to take preventative measures to protect the hive from these predators.

One of the most effective ways to protect the hive is to place it in a well-lit area away from potential hiding places for predators such as tall grass, bushes, or woodpiles. Additionally, beekeepers can install physical barriers such as an electric fence or metal screens around the hive to prevent predators from accessing it.

It is also important to regularly inspect the hive for signs of damage or intrusion. Look for chewed wood or honeycombs as well as signs of skunk or raccoon droppings. If a predator has accessed the hive, it is crucial to remove any dead or injured bees and repair any damage to the hive’s protective coverings.

What Time of Year Are Bees Most Aggressive?

Beekeepers usually notice that their bees are more aggressive at certain times of the year. Nonetheless, even those not engaged in the hobby may also notice a change in the behavior of bees, especially towards late summer and early fall.

As natural food sources run low bees will look for alternative ways to find foods that are high in sugar, which can cause them to land on things like soda glasses, cans, and food that is outdoors. It is also worth remembering that after a summer of foraging for food and high production within the hive, the population of bees will be extremely high. This means that more bees are out and about looking for food. They often become more noticeable because there are more of them about. This can lead many people to (usually wrongly) assume that the bees are being aggressive as they try to source food.

Will Honeybees Attack You?

It is important to remember that honeybees are not natural aggressors and will only attack when forced to defend their hive. When a bee attacks with its sting it will die shortly afterwards, so stinging is only done as a final resort in defense of itself or its colony.

What is considered a threat will differ from one species of honeybee to another. Some honeybees are quite docile and will allow beekeepers to approach the hive provided they are not standing directly in front of the entrance. However, other species, such as the Africanized honeybee, may be more apprehensive about the approach of a beekeeper, even from dozens of feet away.

What to do When Bees are Chasing You

When honeybees believe their colony is under threat, they send out some guard bees to warn away the would-be attacker. Before resorting to a sting, these bees will ‘headbutt.’ If a bee exhibits this behavior with you, the best thing to do is turn around and walk away.

According to entomologist Dr Justin O. Schmidt, it is also a good idea to hold your breath while you walk away from the guard bees. He says that holding your breath is similar to making the bees blind as they use odor to navigate. You holding your breath makes it difficult for the bees to locate you.

The natural response that most people have when a bee is headbutting them is to swat it away, but according to Dr Schmidt this is not a good idea. He said that instead of making the bees go away, it will just make them more aggressive as they think they are under attack.

Are Honey Bees Aggressive – Conclusion

Aggressive behavior in honeybee colonies can stem from various causes. Beekeepers must pay attention to the signs of aggression and identify the underlying cause to address the problem effectively. Lack of space, environmental factors, pest infestations, and genetics are all common causes of aggression in honeybee colonies. Beekeepers can take preventive measures such as regular inspection of hives, providing enough space for the colony to expand, and managing pest infestations. It is also essential to select queen bees from gentle and productive colonies to ensure gentle and productive offspring. Proper management of bee colonies is crucial to maintain a healthy and productive apiary. Addressing aggressive behavior in honeybee colonies is an important aspect of beekeeping.

Beekeeping Disclaimer:

Beekeeping, like any agricultural activity, involves inherent risks. It is important to understand these risks and take appropriate measures to mitigate them.

Potential risks associated with beekeeping include:
